Sunn Concert Lead

I bought this amp used because it was cheap. Everyone said it was loud and they were right. For a solid state amp at 200watts (100/ch)this amp ROCKS! I didn't like it at first but after tweaking the knobs a bit, I got the closest tube sound ever from a solid state. Its rich, warm, fat, and freaking LOUD. It has 2 ch, a Volume, low/mid/hi tone levels, brite sw, distortion level, on/off & Boost sw, Reverb and tone. There are two spkr outputs in the back and I'm assuming they're 8ohms each. There is a wierd plug for a foot switch (which I don't have but would like to) and a preamp out and power amp in. No effects loop.

I have a hand-made Mason Bernard w/emg pickups and a washburn with stock pickups. Both sound rich and full with a bluesy to metal sound. It puts me in the mind of Black Sabbath distortion. Clean channels are loud and clear. I also have a Dean 5-string Bass that I play through the same head and it works great. I have a 2-15 cab on the way for that very purpose. The 4-12 sounds good though.

I have heard these amps are tougher than rawhide. Mine is built very well. It is strong enough to sit on and all of the components are intact. The face even looks new despite the heavy layer of dust embedded into the black covering. It has never let me down.

N/A- Used used used. Will repair locally if needed.

Very versatile for guitar or bass, clean or distorted, louder than most, dependability of solid state with a close sound of a pair of 6L6's. I run this through a 4-12 Peavy roadcase with Scorpion spkrs and it really rocks. I couldn't have done any better with a new Marshall stack! If you have one, it's a keeper. If you don't agree, please send me your foot switch...

Two channels.Channel one has distortion and channel two has reverb. Not shure on the year. I heard it was made in the late 60s.
At 200 watts its loud enough for any one. It came with a 2x15 cab with alnico speakers. All original and vintage solid state.

I use an epiphone and a tele and its sounds great clean for both. Reverb is very vintage fender like. Channel one is much brighter but each channel has its own bright and normal inputs. Cant use the distortion becuase its only activated via foot swich. Reverb can be used with uot switch but can be switched. Hums somketimes but some times very quit. Has a treble boost swich for each channel and is harsh. I need another cabinet to run with the other becuase of the power and gets rattle around 7.5 because of speakers. great for bass to.

Very reliable. When I first got it it broke down so I beat it and now it hasent skipped a beat.

dont know

Its freakin loud. thats all i have to say.

1-Model Year, 1977, I'm the original owner
2-This is an AMP Head, played through custom made cabinets
3-Very good amp in larger venues
4-Very, Very reliable, no work ever done on the amp in 23 years
5-Two channels, 200w.
6-Foot switch control for Distortion and Boost.
7-Front Panel, main, Left to Right: a) Two input jacks, Normal & Brite; b) Volume control (knob); c) Bass control; d) Mid control; e) Treble control; f) Brite on/off switch
8-Front Panel, distortion, Left to Right: a) Distort control; b) Distortion On/Off switch (also controlable from foot switch); c) Boost on/off switch (foot switch as well)
9-Front Panel, Reverb, left to right: a) Level control; b) Tone control.
10 all controls (knobs) are 0-10 incremented.
11-Back Panel: a) 1 sympathetic 115 volt power outlet (used many many times over the years); b) has two speaker outputs; c) Foot switch control connection (not a normal jack), I never recieved mine and would like to get one after all these years); d) Preamp jack; e) Power amp jack; f) Lifetime waranty sticker.

12-I bougth this amp when I was 18. It was too large for where I was playing at the time (but you couldn't tell me that).

13-This is a solid state amp. At the time tube amps were actually going out of style (they were not very reliable then). This amp, however, came the closest to sounding like a shredding tube setup.

1-Gibson Rocking Rocket, Les Paul, Fender Strats and Teles.
2-It is a little noisy at lower volume settings.
3-I have played it through many different cabinets over the years and am currently using a modified Kustom with 2/12" black widows that are ok. The amp was originally paired with a 4/10" sunn cab, but when I bought it, I already had peavy 4/10 and 2/12 cabs. The peavy 2/12 worked the best.
4-I've always been amazed at how well this amp sounded, especially distorted. It was at the time the only Marshall equivelant on the market and it is solid state.
5-For an idea of types of sounds I was/have been going think of Dickey Betts, Joe Perry, Robin Trower, Allen Collins, Neil Young.
6-I have over the years owned pickup truck loads of pedals and affects. Most of these were I've run through this and other amps. However I've always kind of come back to the sounds this amp produces unaffected as my baseline and built on top of it.

I've had it for 23 years, It has played in the rain, an Arizona sand storm, multiple gallons of beer spilled on and in it. Surived many many bar wars. THIS THING IS A TANK!

I've never dealt with the company. I would like to get some documentation if possible. It has a Lifetime warranty, that I've never had to use.

I've been playing 30 years.
I have Les Pauls, Strats, Teles, etc. etc.
I also have a pignose and a fender princeton 2/10 (for a total different sound). Through the years i've gone through an amazing amount of gear and have alway kept my hands on this.
I would like to buy another, If I could find one, just to have. They need to make a reissue.
I wish the foot switch connection had been different, because I never got one the OEM switch and couldn't come up with an alternative.
Finally, this amp head, while small in deminsions, weighs a ton!

This amp was made in the early 70s. Its a good clean amp, and the reverb works great, but i've had problems with the distortion. This is a two channel amp with treble, bass, mid, distortion, and reverb knowbs. If the distortion worked this would be a great amp, but its in the repair shop getting that worked on now. I use this amp in my basement and sometimes at little clubs. THIS THING IS LOUD!

This amp has great clean sounds. It also works as a great bass amp. But i'm working on getting the distortion, and once that gets working this will be an awesome amp. The reverb is outstanding!

This is a very reliable amp, and it has only broken down once(that was because it was in storage for 15 years!). The filter capacitors were dirty so i had to take it into a local repair shop. I got this amp used, and the guy i got it from got it used, and that guy also got it used, so this amp has been around!

Sunn is out of buisness, unless the started up again lately. I think fender has something to do with them. visit www.sunnamps.com

I've had this amp for half a year, and it's done very well. If it got stolen i would get another one if i could find one, but that would be tough! This is one of the loudest amps ive ever played on and it's got a great clean sound. If you want a LOUD amp, get this one!

The SUNN CONCERT LEAD came out in the early '70's...I think? I thought I'd pick one up because it was a cheap, solid-state guitar head. That and it has indie cred for being a durable and unique sounding amp...i.e. "UNWOUND".
The CONCERT LEAD has two independant channels each with a normal or brite input, plus a brite switch(if you dig serious treble this amp can give it to you!) and volume, treb.,mid., and bass knobs. Channel 1 has a distortion knob while channel 2 has reverb. There are inputs in the rear for footswitch activation of the reverb and distortion,(I have yet to get either to work...the reverb is on and the dist. off. It's gonna take some fiddling around inside to work out.)a pre-amp out, power amp in, and two speaker jack out.
I use this head through an extra large Fender 2x12 cab to get a full jangly sound...But,what really blew my mind was that when I ran it through my bass cab I could crank bass guitar through it with great low end tone and plenty of power. Very versatile amp!

Like I said earlier this amp covers the widest frequency range of any guitar amp I've encountered. You want highs, you got 'em and then some. Same for low end(I'm serious about playing bass through it). I feel I need to comment on what great spring reverb this amp has, so full it "gurgles" in a good way...surf city, bro!

Alright, I've only had this amp a short while...I just got it used, and looking inside I saw it had a few burn outs, yikes! But all the goodies got replaced and it seems okay. I know of bands going on rough tours with the same model and it made it through, so...?

I know they(Fender I guess?)are re-issuing some SUNN tube amps, but good luck on getting any service. I don't even bother trying...I fix it myself or find a local service guy.

I really like this amp. I've played through tube amps for a long time, and don't get me wrong they're great, I just think solid state has it's own style. Think of it this way, you could drive your nice shiny '57 Chevy(tube amp) around town, or you could cruise a '78 Cutlas with snow tires(solid state), which, I think is much cooler, scarier, and more interesting.
