Had a chance last night to try my TFB420 with my Schroeder 410 in a large venue/big band setting. 500 seat venue, Piano, bass, drums, guitar, horn section, no pa support for the bass. Brought my upright, Reverend BH5, and Epi Jack Casady..three instruments that are just about as different from each other as they could be. It was supremely easy to dial in killer sound for all three: Upright, dial out some mids at 800, and timbre set a little right of center, enhance off. Boom! Killer big fat woody sound, complete with finger and string noises accurately represented. Reverend: dead flat, except for timbre a little left of center. Killer Casaday: dial out just a little low bass (not the para section), and dial in a little high treble (again, not para), bump the mids a touch at about 800 to help it punch thru, and timbre just a touch to the right. I was cutting straight thru the mix with no problems. Man, the TFB420 eq section is really responsive, and what few tweaks I made were very incremental. Little bits make great big differences. I'm a real happy camper. The TFB420 and Schroeder cab is a simply stunning combination. Lightweight, powerful, compact, tone for days, and a nearly voodoo like ability to tone shape on command and pile drive thru the mix. Pleae note, this is waaay different than "just turning up til you can finally be heard. And perhaps the two best parts: I learned about both here, and I get to support venodrs that support the board. Yeah, I'm a TB-a-holic now fersure. Thanks Dave, Thanks Jorg, Thanks TB!
