Peavey Transtube in a pedal.

[fixr1984]

One of the guitarists in my old band had a peavey trantube amp.

It sounded terribly harsh and was nasty on break up. Didnt take too kindly to alot of pedals either.

one of my amps is a Peavey Express 112. It has Transtube also. By itself with the tube emulation all the way up it sounds pretty chunchy. Put ANY pedal on there and it goes to crap.

[MR COFFEE]

IIRC part of the transtube thing was a center-cut clipping circuit thingy that was supposed to emulate grid conduction in a power amp shifting the bias of the power amp output stage. It was supposed to make the amp "push back" when you played it hard. The "tube compression" deal.

It sounded a lot better on paper than when I played through one in a music store IMHO.

The cascaded gain clipping thing from the patent seems similar to J B 's Vulcandrive stuff. It might sound really good to the Van Halen crowd.

YMMV.
