Schematics and Information on Toneworx Designs

Davy Jones’ Locker – A swampy vibrato preamp and control interface built for Leslie HL722 Rotating Speaker Cab.

1960 Lesmann Accordio-Organ Amplifier Rebuild – This thing is an absolute beast! What started life as an accordion-organ amplifier with percussion, Toneworx has turned into a fire breathing, parallel gain stage, reverberating monster! We reworked the accordion power supply to provide a pedal power source, added reverb, increased the gain, and added the ability to switch between tube and solid state rectification. Pure. Tone. Juggernaut!

Leslie 125 Control Interface – A somewhat simple control interface for controlling the motor speed of a Leslie 125 rotating speaker cabinet.
