We build custom tube preamps for microphone and musical instrument use - including organ, keys, bass guitar, acoustic guitar, and electric guitar.
We can build and install a tube preamp into solid-state Leslie models for "warming up" and boosting the signal as well as providing EQ controls.
We also build preamps for Hammond tone cabinets, so you can finally use that tone cabinet you've been sitting on for something besides organ! For example, the stereo system at the Boss Organ shop is two Hammond DR-20 tone cabinets, running in true stereo, powered by a custom Boss Organ preamp. Now that's what I call Hi-Fi!
