The Underground Accelerator definitely has the Fender Sound with a tube sound thrown in. Check out the specs on Sushi Box. It has the Fender tone stack. Newer versions (after 10/2023) have the same specs as the Hand Wired so, no need to pay extra. I asked Mr. Sushi what the difference was and he said "Bragging rights"!
Just read your edit...I have no idea what it sounds like with a Hammond!
Wouldn't you rather play your "Hammond" through a Leslie?![]()
Yep, it goes through a Leslie, just a second low pass output to go to a bass amp to fatten up the left hand for trio gigs.
