SUNN's "overdrive"

Gibson, Valco, Gretsch, and more

Interesting. I think that they do have a lot of clean headroom (Sunn amps in general). They break up eventually, but only at very high volumes, not unlike the earl 70s Hiwatts. I have a 100S and 200S. I haven't had the nerve to turn either amp all the way because they are so loud and I don't want the police knocking on my door, but I have come closest with the 200S and it does overdrive nicely. Since both the Who and Hendrix (to name a few) played these amps during their careers, the fact that they sound good overdriven shouldn't be too much of a shock. Sadly, I am selling the 200S because I have just too many amps!

Coliseum PA amp...

Postby tubetek on Mon Mar 06, 2006 11:47 am

The SUNN Coliseum PA amp was most notably used (as a guitar amp)in the late 60s-70s by the great, underrated Leslie West of Mountain. They use KT88 outputs, DUAL tube rectifiers, dual chokes,and HUGE transformers; Great for Loud n' clean (bass etc). Don't hack it up, it's a classic (just expensive to feed!!)

But in was really not clean..
One of the most surprising natural overdrive sound I have ever heard..

Don't you think it is comparable to an Orange OR120 ?
The high powered Sunns, Oranges, Ampeg V series, Hiwatts, Sound Citys are all "loud and clean" amps. They have natural overdrive, but not untill you get into the ear bleeding volume levels, i.e. cranked.

It sound like a Model T reissue to me. I've owned several old Sunns, and no matter how much I cranked them they never got fuzzy... barely any overdrive... just brutally loud.

I used to own a Sunn 2000S with KT88s and dual recto. Pretty much what youre talking about. If you cranked it (which I did often) it would distort nicely. Not clean at all. Leslie West didn't get a clean sound either out of one.

Yes, Model T. I bet he had some sort of pedal to make it distort and be fuzzy.
