CUSTOM
HANDWIRED BOUTIQUE
Everything I build and repair is done with heritage craftsmanship and top notch military grade components.
Although I revere much of the outstanding equipment built from the 50's-70's (Ampeg, Fender, Magnatone, Mu-Tron, and Orange… to name a few influences) - I like pushing boundaries sonically and moving what analog gear can do into the future with innovative ideas.
I like effects and amps that operate in true stereo and accommodate more than just Guitarists. Bassists, Synth/Drum Machine users, and even Vocalists should be able to have awesome Vacuum Tube amps/effects too.
I can make many pieces of gear designed custom for the prospective customer - But I have two main electronic designs that I can make available at any time produced as one-offs: A hand-wired Fuzz/Fixed Wah Pedal and a Hand-Wired All Tube amp focused on gain.
