Wow, that's realy... uh... BIG. No matter. You can put it in a hardwood furnature style cabinet. The jazz guys will eat it up.
I've done the dedicated reverb thing before. It works great. I ran my tank by filtching power off the main amps output. I don't SEE a tank in your pic so I don't know if your using one. But if you are I can tell you that running it off the main amps output and then dedicating a recovery amp and speaker works really well.
The trick, IMHO, is to market directly to jazz players in their publications. They seem to like funky quirky stuff with a different sort of design.
Some of your features seem like stuff one might do because they could rather than because they should. But if you consulted a bunch of players about what they want and the amp sounds good then it's great. Looking forward to hearing the clips.
BTW, if you wanted to try the 'run the tank off the main amp' thing I won't get wierd like you took my technology. Gibson, Hammond and others did it almost fifty years ago.
