Randall Pro-Tube 1000 II

Hi mine is a 1993 5 pre amp and 2 power tubes. It has 2 chanels clean and distorted. It has reverb seperate eq for each channel and a gain voicing switch for channel 2 seperate volumes for each channel. The amp has plenty of featchers

The sound quality is just awsome. The clean channel is very clear. The distortion channel is very brutal. The only downfall is to get a real blues chruch sound you have to use a pedal on the clean the distortion is way to heavly although I never tried to change the pre amp tubes frome anything but 12ax7 (high gain tubes)

Ive owned it for 8 years never had problem

They no longer make this amp. But I emailed randall for a schematic and they sent me one the next day.

Mine was a 1993 that I bought in 2002 on ebay sound unheard. I no longer have it, so I have to do this from memory, but I have the original ad and notes I made and all. It is a 2-channel all tube amp. Clean channel Vol, B, M, T & Gain. Pulling the Gain knob turns on the gain for either channel, if I remember correctly. It also has a EFX Loop and front knob for the EFX Mix Level. Pulling out the EFX Level knob gave adjustment to a "Presence" function, very useful to me.

Channel 2 ("Dirty") had its own B, M, T and a Master Volume as well as sharing the Gain control.

Also had Reverb, both channels, I believe. A 1/3 Power switch; a circuit breaker instead of fuse, imho a very useful feature; Speaker Out and EFX In & Out. A single 12" Speaker completes the features that I remember.

This was my first (and still only) tube amp, so put my comments in perspective. The first guitar amp I bought was in 1986, a Roland Jazz Chorus 55W that I picked out over several only modestly cheaper amps even though I knew nothing about them. So I do have some ear for tone.

I thought this amp was very loaded with good features and that was why I bought it for $300 on ebay.

It did everything I needed... Surf, Classic Rock, Folk Rock and some Deep Purple and such. I thought the 1/3 Power Switch and CB instead of fuse were especially useful and all the rest had the basics. Also a footswitch input (a generic worked) for the channel changes. Not perfect, but for the price... damned good.

I haven't played (electric) on stage, so I'm not positive, but I would think it had plenty of power for all but the largest venues. The only thing I can think of it missing is a Vibrato, so I'll take off one point for that.

First of all... I had been trying to get a certain... tone. I had the JC55, which is an OUTstanding SS amp. But I had tried everything... even some pedals, most notably, a Dunlop Cry Baby 535Q that also shaped the sound and some other. The Cry Baby almost did it, but not quite.

After talking to quite a few people on an online forum, I was convinced that a tube amp was the only way. I couldn't afford the standards at $800 to $1,000 (in 2002), so I trolled ebay for the deal on this one.

To sum it up... I was blown away!!! It was AWESOME!!! All the sounds I wanted plus some! I used it almost always in the 1/3 power mode, which I know now gave me better (tube) distortion at lower volume. I tried it out at work one time (BIG almost empty corrugated metal bulding (100 ft x 40 ft?) and 15 to 20 foot ceilings. At about 7 or 8, it was PLENTY loud enough. As I put things away... I discovered I'd left it on 1/3 power!!!

I couldn't find anything to flaw in the sound. The two channels, gain and presence gave a good variety of tones. It may be because it was my first tube amp, but I thought it was positively awesome. The guy I bought it from had already re-tubed it with 6L6 and I never did try the EL-34's that he sent with it. I played it with the back off and on... like it better on... tighter lows and such.

It never broke down on me in two years. Never a problem. Can't imagine any (at a gig) that could not be fixed by resetting the cb or having a spare pair of power tubes and one pre-amp tube. btw, it had the 12AX7 Pre-amp tubes, but I don't remember how many.

But, since I didn't have it for that long... only played an hour a day at the most, or gig with it, I'll have to say "No opinion".

Here's where I differ from the rest of the reviews here. It did take me two or three emails, but I did get a copy of the manual and schematic of the amp... even though it was discontinued. I thought that was pretty good so I'll give it an 8... it did take more than one email.

As I've already said, I couldn't find any fault with it and I thought the sound was awesome. Oh... one negative... it weighed over 50 lb. Of course that's true of ANY tube amp, but I'll take a point off for it. It was a beast to carry.

I've played guitar for almost forty years, mostly acoustic. I started "playing around" with electric guitars in 1986. My first amp, the Roland JC55 was a winner, and, imho, so was this one. I play Folk-Rock (Dylan, Guthrie), CCR, Classic Rock and like that. Some harder 70's and 80's stuff, which this amp did very well. But it could do the other, pretty clean stuff as well. I'll mention here that I don't really care for the "super-clean" chimey Fender amps. I used a Fender Strat Highway One, Korean made H-S-H and Martin D-18 with Sound Hole Pup thru this amp. The amp handled them all well. Handled EFX pedals well too. In particular, the DOD Mystic Blues, Cry Baby 535Q and George Dennis Distorted Mind Rock was about all I could see needing except for delay and the amp was rawkin' with them!!

I brought this amp new in 1991, mine is differentthan any other in your reviewa. Mine has 4 tens, and blonde cover. two channel or both.
amp works well with no trouble in 13 years. reverb is weak for me i mostly play rock-abilly

I usuLLY PLAY FENDER TELS OR GIBSON SG WORKS WELL WITH BOTH. MY AMP WAS NOT NOSY I CHANGED TO GROOVE TUBES BEFORE IT WAS OUT OF THE STORE, AND IT HAS ALWAYS WORKED GREAT. I HAVE PLAYED WITH SEVERAL PLAYERS USING FENDER 59 BASSMAN AMPS, MOSET LIKE MINE BETTER. I DON'T USE THE DISTORTION BUT USE A DANELTRO ELCO WHICH IS GREAT FOR MY SOUND

I GIG, AND USE THIS AMP AT HOME, I HAVE NEVER HAD A PROBLEM

I HAVE NEVER HAD A PROBLEM, NO CONTACT WITH COMPANY

I HAVE BEEN PLAYING FOR OVER 40 YEARS. THIS IS THE AMP I GO TO, I HAVE 5 OTHER AMPS, ONLY REGREAT IS THE NEED FOR A BETTER REVERB.

Two channel, separate EQ for each channel. Effects loop. 2-6L6 or EL-34. 5-12AX7. Third channel for combined clean and overdrive sound. Gain voicing. Use this amp for small clubs and medium venues. I play kinda of a Grissom/Gibbons style but try to add my own touch.

This is an odd beast. It does sound significantly better with 6L6 output tubes rather than EL-34s. Even at Lower volumns there is a buzziness to the sound with the 34 tubes. It's tough to figure cause it sounds like a pre-amp thing. I'm assuming when you switch the bias they set a voicing change in the preamp. Just odd. But hey! With a set of Sletvana 6L6 in this thing it screams. Have to keep the Gain at about 9:00 on the lead channel but you've got two usable channels with the clean channel a bit more in your face than a Fender and decent swirl. The combined channel option is as of yet totally unexplored but I've heard some interesting things from it. It totally changes the effect of the preamp volume control when you do this. So it can mess you up in a hurry.

No problems yet.

The amp is no longer produced so I wouldn't be optimistic.

Great amp for the price. Be prepared to tweak and realize that this is similiar to a Boogie and it will sound alot different on stage than in a bedroom. Useable tones and its loud for a single 12" amp.

This is a two-channel, 50-watt, tube amp modeled after a Mesa Boogie or other multi-use '80s amp. It is loud! I have had it for a year. I got it used at Music Arts Enterprises (MAE) in Fort Lauderdale, Florida. It appears to have been made in 1991. It has a Celestion 70 watt speaker and came with RL34 power tubes.

Although the amp is made to accommodate a footswitch, it didn't come with one and I haven't gotten one since I just play at home. It has an effects loop but I don't use it much. Instead, I just hook up my Morley wah pedal and a Zoom 505 pedal between the guitar and amp and get a good sound.

I play two guitars through this amp. My favorite is an Epiphone Les Paul Jr. with two P90 pickups. The other guitar is a slightly ridiculous looking Kramer Randy Rhoads model that I got for $25. The Les Paul Jr. has a nice, jangly R&B and blues tone. The Kramer is made with one intention - fat humbuckers through a Marshall stack! I play it when I'm looking to relieve stress!

I play mostly blues and some R&B so the Les Paul Jr. is the main guitar. The Randall amp was attractive for its relatively low price and warm clean channel. However, as others have noted, the amp as it comes from the factory has essentially two sounds - clean to 10 on the clean channel and Heavy Metal on the gain channel. It also had a pretty annoying buzz from radio interference when I got it.

The limited sound and buzz was driving me crazy so I did a little experiment and discovered the solution, which I want to pass on to others. The amp is set up to accept either EL34 or 6L6 power tubes. It comes with EL34's and, because of that, gets a pretty screaming Metal sound on the gain channel. I put some Mesa Boogie 6L6 tubes in this sucker and now it gets the tonal variety I was looking for! In fact, it sounds better than some of the recent Fender amps I've heard in stores and no longer has a buzz.

This modification cost me $38 and made a world of difference. I am totally satisfied with the sound now. The clean channel gets more bite as you turn it up like an old Ampeg or Fender Twin while the gain channel still screams but with a little more treble edge. The clean channel now gets a great blues tone with the channel volume set at about 3 or 4, treble at 6, mid at 5, and bass at 4. A few tweaks of the excellent tone knobs allow me to still get a pretty good Marshall kind of sound if I want. Incidentally, the reverb on this amp is pretty good. I set it at 5 and forget it.

I generally stick to the clean channel but, when I pull out the Kramer guitar and do my best Hendrix impression, the amp can still kick butt! It has what appears to be a parametric EQ on the gain channel called "gain voicing." I set it at 6 and get a fatter, more liquid tone which works well for Hendrix or Leslie West kinds of things.

I don't take this amp out for gigs so I can't say how reliable it would be in that setting. However, I have had occasion to leave it in the trunk of my car for days on end of driving and it never missed a trick. Since I replaced the power tubes, it has worked admirably. I give it an 8 for reliability because it did have a buzzing before I changed tubes.

I've been playing for years in my limited little blues world. Guitar playing is a hobby I enjoy. I also play acoustic guitar on a Takamine that is about 15 years old.

I now feel very good about this amp. I recommend it to others as an affordable gem with hidden potential. Just add good quality 6L6 tubes and enjoy!

If the amp was stolen, I would certainly look for another as a replacement. It has great versatility and, with the new tubes, excellent tone.

1x12" 50W tube combo, 2xEL34 or 2x6L6 (w/ bias switch on the back of the amp for user-switching of the tubes), 5x12AX7. SS rectifier, G12M-70 Celestion.
This amp has two channels, clean and high-gain. Clean channel has volume/treb/mid/bass, high-gain has separate gain/volume/treb/mid/ bass controls. The pull-pot on the high-gain volume acts as a channel switch. The high-gain treb is a pull-pot for presence.
In addition, the dirty channel has a Gain Voicing pull-pot. This knob affects the gain voicing in what seems to be a parametric mid- boost fashion. Out for more midrange scoop. Reverb (prolly SS driven) knob and master volume round out the front knobs. 3-way switch on front for ON/OFF/Standby, not the best choice -- two switches is MUCH better.
The back has a fixed serial effects loop, 1/3 power cut switch (allows output stage distortion at "lower" volumes) two 8-ohm speaker outs, and a footswitch jack.
The two-switch footswitch allows you to switch between the clean and high-gain channels, and to switch on a "both channels" mode which mixes the clean and high-gain channels. This "both channels" mode increases gain and mixes clean sound into the signal.
This is definitely a two-channel amp -- clean and metal. The high-gain channel is crackly (SS-like buzz) at low gain levels. Only at high-gain settings does the overdrive sound big. No blues tone at all via the preamp. Diming the clean channel at 1/3 power will, however, get great output stage distortion, but LOUD. The clean ends at clean and high-gain starts at crunch.
Other caveats: fixed serial f/x rather than parallel w/ mix. The reverb is decent but cold and somewhat prone to crashing with amp movement. The fixed 8-ohm speaker outs can be a pain with 2-speaker cabs.
BTW, the poster who said 200W mistakenly looked at the AC rating printed on the back.
Good channel features, but the gap between clean and dirty and the other caveats earned the 8.

The clean channel is very good -- very warm and sweet. It does not have the glassy Fender treble, though it can be fairly bright. With single coils, the only distortion you'll get out of this channel is power stage. With humbuckers, this channel clips nearly inaudibly (in an ugly SS way) above 2 on the clean volume. But you'll get all 50W of clean if you want it.
The dirty channel is a high-gain wonderland. You can get ballsy midrange crunch or scooped mids with just about any pickup. I'm into rock/blues, and this amp is NOT intended for this purpose. Good, very flexible gain voicings for hard rock to metal and up. In the end, the gain sound thins out with volume -- not a Marshall stack replacement. Doesn't warm up for leads.
The amp is quiet except for the ludicrously noisy "both channels" setting. Can you say "radio station"? Not sure what purpose this setting serves; would have preferred foot-switchable reverb.
I've kept this amp for the clean sound. In full power mode this amp gives great warm clean with plenty of headroom. In 1/3 power mode, pushing the clean channel gives a great throaty groan that I like. The high-gain is wasted circuitry for my style of playing.
A ten trick dog that only hunts for one.

Randall included some really crappy tubes with this beast. Replace the original microphonic chinese 12AX7s/EL34s with good tubes and this amp will stop rattling, feeding back, and otherwise misbehaving.
I've had the amp for ~4 years. Not much playing on this amp, but besides tubes nothing has gone bad. The internal construction is PC board, but decently done (better than Peavey, but not as good as Marshall, Mesa, etc.). VERY heavy. The transformers are large and the speaker is quite heavy as well. Not as heavy as a 4x10" combo, but quite heavy for a 1x12".
My niggle is that the painted knob labels on the front are chipping off without much reason. You may at some point want to write down the knob functions on paper. :-)
Probably a 5 on the reliability scale from what I've heard about Randall. But in real life? How many times has Randall been sold and to whom? I'm sure this amp is no longer in production, so the warranty may or may not still hold (if it's transferrable). No guarantees.

Never used.

I play a AmStd Strat w/ Van Zandts and a PRS Custom 22 through this amp. I've been playing for about 9 years on and off, and my style leans towards dirty blues or ambient alternative. I like the warm, deep clean sound and the (albeit loud) power-stage distortion. This is not a bedroom amp for medium overdrive!
I would buy it again if the price was right. I'd have a hard time buying 50W of sweet clean headroom for the <$200 this amp would probably ask for on the used market. But as a channel switcher there are much better overall channel switchers out there for the price I originally paid (and less).
This was my first real amp (after my SS Traynor 15W). Sound was heaps better than SS, but I wasn't a picky buyer at the time.
If you want a backup amp or have a rack or pedals for distortion, the clean channel of this amp should give you a great, cheap tube foundation.

It is a 200 watt tube amp with gain voicing ( good tone / bad tone), reverb and heavey overdrive distortion. It has an effects loop and a footswitch, 2 speaker outputs, and a 1/3 power switch that doesn't seem to do anything on mine. The speaker is about 11 inches.

The distortion is massive and bassy and is good for rythm but I don't like it for lead. It would probably be good for industrial. The reverb seems medium, the normall tone without distortion is real good but a little flat and the tone controls aren't that good.

Has tubes, but has been good so far. It seems almost as reliable as a Peavey.

Haven't needed it.

I would buy it again, it listed for much more than what I got it for, but I would look around a little more next time.
