A batch of 100 new design TUBE DRIVE pedals are almost complete. I’m just waiting on chickenhead knobs (authentic U.S.A. manufactured Dakaware, not the Chinese copies) to be delivered. If you’d like to get on the wait list please contact us direct via email to reserve one. The TUBE DRIVE is designed for flexibility, ease of use and outstanding guitar tone. Three thermionic vacuum tubes make up a cascaded symmetrical clipping circuit and active ‘Baxandall’ tonestack. The clipping stages operate in single-ended class A at real amp plate voltages to deliver exceptionally natural and musical overdrive.
