Re: School me on the Bogner Ecstasy 101b.
The only way to be schooled is to own one because it's too vast to have it sussed up by demoing it in the store.
As for compression, the amp has one great feature for controlling it. With Bogners, the compression is designed to give it a full throttle cranked sound. The XTC has one presence for two channels, with a second presence you can assign to either the red or green channel. This allows you to lessen the compression on the red channel or add sparkle to the green channel.
Also, there's different versions of the XTC.
If you have one with Class A/AB, you've got another whole tonal dimension.
Tubes also play a big role, as with any tube amp. Mine has been dialed in for years, because I spent some time popping pre tubes in and out. I think it's now a combination of EH and Tungsol pre's with JJ E-34L's.
The Ecstasy is loud, but it's got a great master volume. Also, Class A, half power, and FX return give you a lot of ways of taming the volume without sacrificing tone or feel.
The Ecstacy was the brainchild of perhaps the most important amp designer in modern times. There's other great amps out there, but Reinhold Bogner has created a better collection of incredible designs than any other. Where others are hit or miss, Bogner hits it out of the park every time. If money were no object, I'd own a whole bunch of them.
