Used Thunderfunk TFB750-A
Locally owned and gigged sparingly, this U.S. built amp is rather sought after and in short supply. It's loud, warm, flexible, and thoroughly over built. Here's the breakdown:
"Thunderfunk Bass Amps are the direct descendants of the amp that Jaco Pastorius loved, the legendary AMP BH-420, improved, and handmade in the U.S.A. by Dave Funk. With an all-aluminum chassis, the TFB750-A weighs in at only 21 pounds. Quieter than other amps, with two great sounding DI's, it's perfect for Studio or TV use.
The Thunderfunk's tone is achieved by using high quality film caps in the preamp's signal chain... just like a high quality mixing board. Twenty-five times more expensive than electrolytics used in other amps, film cap's tighter tolerances maintain phase coherence through the amp, producing a focused punch unlike any other amp. Add two to three times the filter caps of other amps, you get a round, focused bottom that doesn't roll around the stage but instead projects into the room.
Dynamic range is a function of power, transient response, and quiet. Thunderfunk purposely doesn't use toroid transformers as they've found they don't sound as good as the old-fashioned "EI" iron. And to reduce hum, they add a "hum-bucking" wire across the transformer to inject hum into the preamp's ground cancelling the radiated hum achieving an amp quieter than an equivalent toroid powered amp. With their unique "SS/Tube Switch" you'll be able to choose from a super clean solid-state tone for slap and double bass playing, to a gutty, warm, tube-tone for all the rest."
