Mojotone Discrete Hi-Voltage Series Effects Loop for Vacuum Tube Amplifiers

Optimized for insertion between your preamp and phase-inverter stages, this low noise, non-clipping effects loop utilizes a discrete, high voltage buffer and a return gain stage. Includes true bypass.

Installation requires 4 wires, power ground input and output.

Required supply voltage: between 150V-350V dc

Detailed instructions are available in the installation PDF manual

The stock setup offers a send with 10dB of cut and a return stage with 16dB of boost. The signal path can be reconfigured with panel mount pots, or trim pots (not included) or by changing component values on the board for a modified fixed installation.

The stock board has been well tested in British 45 and British 800 installations and is quiet and highly functional.

Wire is not included since you will probably want to use cloth covered wire in Fender installations and PVC coated wire in British amps. Our installations did not require the use of shielded wire.
