MXR Micro Amp

MXR Micro Amp.
Only one knob and one switch. Very easy!
No secret - I dont need the manual to find the ideal sound.
If you is looking for a boost pedal for solos, this one is the best thing. No doubt.

It doesnt change the sound when putted in action. It just increase the volume of my amp. I put it in front of my amp. If you put it before of drive pedal it only will increase the gain... Although many people uses the pedal for this function.
No noisy!

I didnt notice difference in delay, chorus, reverb... I think it doesnt change too.

Important
If you want to use the Micro Amp to increase the VOLUME of drive channel of your amp... You must plug it in send/return - So I will work finely in channel drive too... If you plug it in input It will just increase the gain of channel. Be careful.

I never had problem!

I never had problem

Excellent for me!
After I purchased the Micro AMP I gave up the search for volume pedal.
It is great for my solos and It never change tone of my amp... This is important for me.

Advice: Buy it... Dont waste your time... It does the job perfectly!
Dont use a TS9 as booster - TS9 is TS9 - Booster is Booster...

1 knob, doesnt get any easier than that.

I just purchased mine from a music shop in Haight (San Fran) I live in England and we dont quite have the choice of boost pedals over here that were in the shop to try out. In fact every time I have been shopping in England (usualy at a sound control or similar) when you ask if they have any boost pedals in stock they reach for a ts9 and when you say 'I already own one' thay look at you funny.

Anyway, my mxr was $99 and i compared it to a boost pedal made in san fran by small company forget the name that was $359, The mxr was by far the better pedal. The boost was 'crisper', clean when you want it to be but responsive enough to give the tone a 'push' when needed.

I am currently running the pedal in a chain with a guyatone comp, ts9, daddy o, boss digital delay (japanese) and a messa v twin. Mxr works well as a boost for the clean channel, for clean soloing, but works especially well with ts9, allowing for 2 different volume settings.

I play a custom strat with noiseless pick ups. The pick up out put is quite low which is good for certain tones but the mxr placed in the correct position in the chain drives the effects that bit harder.

Sounds great with my fender deville and my groove tube stpg.

This pedal is a must for anyone who uses a ts9 for rythm and soloing. The most common mistake of amateur guitar players is that there is no disernable change in their rythm andsoling volumes. The mxr fixes that problem.

Doesn't get much easier than this.

This is the single greatest pedal I have ever purchased, bar none. I've been playing through a Fender Super Reverb reissue for two years now and, while I adore the clean-grit of the amp (with the volume at 6 or 7), I needed something to push the tubes a little harder without totally compressing my tone and sucking out the bottom end. This Micro-Amp was my answer. Basically it makes my amp sound like it's running at 9 or 10 without increasing the volume overly much. I generally keep the knob set at 3 o'clock, though there's a wide swathe of usable settings between halfway and full. Yields a decent amount of good harmonic feedback, no noticeable noise or hiss, and it doesn't destroy any of my natural guitar or amp tone at all. My setup: Fender Telecaster -> ProCo Rat (when a total explosion is needed) -> EH Dlx Memory Man -> MXR Micro-Amp -> Fender Super Reverb.

Totally dependable. Built like a brick shithouse.

Never dealt with MXR, though with a pedal this tough I don't see why I'd ever have to.

My band plays a fairly eclectic and technical mix of hardcore, metal, and art-rock, with an emphasis on jazz harmony and complex meters. The other guitarist plays a barrage of pedals through a JCM 2000 and generally covers a lot of the textural parts, whereas I'm much more of a bare-bones player; thus the Micro-Amp is well suited to my needs (though it's probably not sufficiently over-the-top for my co-pilot). I've been playing for 12 years. I would replace this pedal immediately if it ever (knock on wood) disappeared.

This product is extremely easy to use.

It seems that most of you have overlooked many of the features of this product. The Micro Amp is far more than device to provide a solo boost. This is a great active preamp.

- The output from the Micro Amp has a slightly lower impedence than most pickups directly. Most effects pedals and stomp boxes are driven better by this slightly lower impedence.

- By putting it first in your effects chain, the combination of the slightly lower impedence and higher output means that you can drive long chains or effects or longer cables without a signal loss or rolloff in high frequency tone.

- If you switch between guitars you know how different pickups provide very different output levels. The micro-amp, allows you to quickly equalize the output from various instruments. So if I move from a Les Paul to a Telecaster for example, you can boost the preamp to mainatin your overall volume, overdrive levels, etc.

I am a long term pro and always use a Micro Amp. In fact, I connect my Micro Amp to an MXR 5 band graphics equalizer, to a Digital Delay, to an Ibanez Chorus, to an MXR Phase 100. This goes directly into a Fender Tone Master head connected to a Fender 212 bottom outfitted with JBL speakers. I also use a Music Man 112 RD-65 amplifier.

I primarily play blues and use a '67 Guild Starfire IV outfitted with Dimarzio PAF humbuckers, a stock Telecaster, and a Les Paul Deluxe also with the Dimarzio PAF's, and a 1981 Stratocaster.

In most concerts, I tend to lean towards the Starfire and the Telecaster. I also switch between them often during a performance. The stock tele has significantly lower output than the Starfire, so I use the Micro Amp to equalize the output between these two guitars.

From time to time I add an MXR Micro Comp compressor to the mix when I'm forced to play at low volumes such as in very small rooms. In these cases it is not alwats possible to drive the amps to a nice bluesy sustain. The compressor adds sustain and give me a chance to sound really loud at low volumes.

I have had mine, built by the original MXR Factory for nearly 30 years without a single problem!

Hola, escribo en espa?ol porque creo que mi idioma es bastante conocido en todo el mundo.
MXR micro amp, muy facil de usar. un pulsador de on-off y un pot de gain solamente, pero tremendamente efectivos.
Solida construccion.

Es un booster tremendamente efectivo, realza el sonido de la guitarra, sin modificar la ecualizacion.

Nunca he tenido que usarlo.Solo lo tengo unas semanas, aunque creo que en Dunlop no hay problemas en caso de averia dentro del periodo de garantia.

Toco Hard Rock, Jazz-Rock, Jazz clasico Y mi amplificador es un Mesa Dual Rectifier.
El micro amp es un fantatico complemento de mi amp.

Understand the application of this pedal first. If you are a bedroom wanker that needs a Zepplin or a Ride the Lightning sound, this pedal is not for you. Serious musicians only, please. Where it shines is 1) on the front end of a non-master volume tube amp, where it can slam the preamp with so much gain that it'll sound like that old tube amp is going to explode, or 2) in the effects loop of a master volume amp to serve as a solo boost.

I'm playing this through a Fender Hot Rod Deluxe. The amp has a clean and dirty channel, along with a gain (distortion) boost. It can achieve three really good sounds, but solos get lost on stage. With the little MXR in the effects loop, though, I can add the right amount of solo volume. It works great! I also put it in front of an old 5-watt class A tube amp and I sent that thing into super overdrive! The pedal is quiet and no "pop" was heard when switching it on or off with the pedal plugged in.

The box seems pretty sturdy, and there's just not much to break. I don't feel like buying a second one right now, so yes I'll gig w/o a backup. Giving it a 9 just because I haven't had it very long.

Rocked-up Texas Country/Southern Rock. This pedal lets the solos shine. Been playing for 15.5 years, and I'd buy another in a heartbeat if it got lost or stolen. I love the simplicity of it. There was no comparison to any other model. This is it!

Just like everyone says 1one knob one switch. Good clean boost if in the right place in your chain.

I use three different guitars depending on my mood and sound I want. I have a G&L Comanche, Class 5 Les Paul, and a Heritage 555. I have a Diamond Pedal J drive, Keeley Blues Driver, Keeley DS-1 Ultra, original Big Muff, Vodoo Labs Micro Vibe, Keeley CE-2, 2 Keeley DD-3, then the micro amp all going through a GCX switcher. All going through a THD Univalve into a 2x12 cab loaded with 12" Tone Tubby Alnico speakers. I use the Micro Amp after one of the DD-3's for a lead boost with any combination of the Distortions I use. I use it as the last thing befor the amp. I tried it before the delay but it made the sound just a little thinner. After I moved it I got what I was looking for a nice boost that didn't color my tone. I have the knob set to about 11:00. I have the tones I want so I all I wanted was a nice clean volume boost fo solo's.

I opend the back when I got to make sure there was not a battery in it. Since I use it with the switcher I have a power adapter on it and it sits on a shelf in my rack system. I noticed that the foot switch was right on the PC board. I could see where this could be a problem if you are consitantly on the switch. I don't have to worry about that because it is always on so it should last the life of this set up and further. I will give it a 7 because I do thing the switch position is asking for trouble.

Never delt with Dunlap

I play mostly Rock and Classic Rock type stuff. I have been playing for over 20 years and have put in my time in the bars and clubs. If it were lost I would buy another one. I know there are other boost out there like the Keeley Java Boost but for the price and what I want it to do this is a great buy. If all you are looking for is a clean volume boost then this is the guy.

Very easy, just like everybody else has said. 1 dial and 1 switch - anything else would just work against you in this case.

Depends almost entirely on the equipment you use it with.

I'm using it in the efects loop of a Marshall DSL401 (40W 1x12 all valve combo) and originally bought it to provide a "lead switch" on the OD2 channel in the same way that my Mesa Single Rectifier has a "solo" button to provide a volume boost. Since plugging it in, however, it's effectively converted my amp from 3 channels to 6:

Clean = Standard Marshall clean
OD1 = Light rock distortion (Status Quo sound!)
OD2 = AOR and classic rock rhythm / lead
Clean + MicroAmp = Boogie "pushed" sound (crunchy distortion)
OD1 + MicroAmp = Heavy rock rhythm (louder than OD2 but less overall gain)
OD2 + MicroAmp = Rock / metal / shred lead solo tone and boosted volume

Obviously, another amp will respond in a different way, and the sound you get depends on how your amp likes being overdriven, but my Marshall sounds great with the gain boost, so yours probably would too!

It's suggested in the manual for this pedal that you place it in front of the pre-amp, but with that setup, the volume boost is much less, and given the high-gain amps and active pickups that are common these days, it's feasible that the increase in gain will either go un-noticed or just translate into feedback and noise. Having said that, try it, it might be just the thing to give a lower gain amp some more bite...

The bypass of this pedal is the best I've heard, and the switching is near-silent; it's actually quieter and faster than the channel switches on the amp's foot-pedal itself, which makes it a very good "solo" or "lead" switch, as you don't get a pop, or a drop in volume when you use it.

There is some hiss when the unit is in use, but it's nothing that you'd hear over your playing, and it should probably be turned off in quiet parts of a song anyway!

If you think you can get the same effect by using a Boss GE7, you're wrong - I tried it, and this is in a whole different league.

Seems very sturdy, and the switch on mine is metal, not plastic as other reviewers have stated. I'm guessing that it should be dependable.

The switching is silent and the bypass is as true as I've heard, so I assume it's well engineered. Plus, at heart it's an op-amp in a box - how difficult can it be to get that right?

I fully intend to gig without a backup, mainly because if it failed I'd manage without just as I did before I got it!

Never contacted them - it's the first MXR / Dunlop pedal I've ever owned.

It doesn't really matter what equipment or musical style you play in this particular case. If you want more input gain or a volume boost to the power amp, and you like the tone you have already, you'll probably love this pedal. It does exactly what it says, and nothing more or less. I suppose it might interact with other effects, but I don't use any, so I can't comment.

My amps are a Boogie Single Recto 50 and a Marshall DSL401, and I got so used to the lead switch of the recto that I wanted one on the Marshall too - this pedal has provided it without altering the fundamental sound of the lead channel, plus provided a way of adding some extra power tube distortion to other channels as an added bonus. In all, I think it's a great product!

That said, some may not need it - I wouldn't use it on my recto (because it's got a lead switch and tonnes of distortion already) and I certainly wouldn't try and overdrive a transistor amp with it... just because!

If you have a valid reason for owning it, I don't think you'll ever look back. If you think it's a distortion stomp-box, you're wrong, and you'll be disappointed.

Easy enough. :) One knob, but do you put it in your effects loop or right in front of the amp? I'll get into that below...

I use Jackson guitars, all with humbuckers, straight through a Carvin X100B. This is my only pedal. It's pretty noisy past the 3/4 mark, but...you don't need to turn it all the way up, in fact, please don't...the world has enough louder than hell guitar players! Anywho, I put it through the effects loop as a lead boost, and boy does it boost. No complaints, it does the job just fine without sacrificing your amp's tone. If you put it in front of the amp however, you get a completely different effect. It almost acts as, well...another gain knob for your amp! It compresses the signal a bit and adds some nice sustain...creates even more feedback for ya, the good kind.
SO - if you want this to boost your volume, put it through the effects loop and adjust to your liking. If you want to subtle "gain boost", put it in front of the amp. Rarely will you need to go more than halfway either way.

I have a brand new version, the one with a plastic on/off switch...it's lasted these past 8 months, but common sense should tell you the older version with the metal switch is much more reliable. Keep that in mind when you're reading others' reviews. It has lasted a while, but I'm not very keen on the plastic switch.

If you need a volume boost for your leads, and don't want to mess with your tone, this is the pedal for you - just make sure to hook it up through the effects loop. It's not noisy at all as long as you keep the gain knob at a reasonable rate. I personally would like another to put in front of the amp and have on at all times...at the lower settings, say 2-3, it simply provides more balls without distorting the signal of your amp. I really like this pedal, and although it's very simple in design it's pretty versatile if you think about it. Price tag's a bit steep. Cheers!

Simple operation which immediately gives you what you need, which for me is for going between rhythm and lead.

I use an SG, and LP or a G&L Legacy through one of two vintage Traynor heads (EL-34 and EL-84) with no master volume. Of course it is noisy at rest with the pedal engaged to close to max level, but that can be expected from an additional 30db of input gain hitting my amp. That being said, it?s no worse that single coil hum, so you don?t notice it when you?re playing. It sounds great because it keeps the integrity of my amp and guitar?s tone (I use no effects) and makes my leads scream.

The footswitch can be finicky once in a while and so too can the AC plug, it?s my only complaint about this pedal. I also have a Fulltone Fulldrive II, which gives me over the top overdriven leads and feedback (otherwise not achievable with the Micro Amp with my set up), and can also come in as a backup if needed. However I prefer the transparency and volume boost of the MXR.

I play blues, rock and hard rock and kick in this pedal to do 95% of my lead work ? it matches up really well with my amps. I?ve been in a band for 7 years and I keep coming back to this pedal, as no overdrive pedal can match what the Micro Amp does for me (no matter what, OD?s color the tone or drive it too much, even at low settings). It?s also a bargain compared to OD?s and other clean boost pedals. I also like the rubber knob cover which allows you to adjust your gain level by foot.
