All tube FX-Loop add-on module that can be fitted to virtually any guitar tube amplifier. It’s based on 6N17B sub-miniature dual triode. This is a series FX loop, it will pad the send level -20dB and can boost the Return input level up to 30dB. Both are adjustable

The module has options for 1" or 1.5" jack spacing and will ship with only one jack installed. The second jack and trim pot is included for you to solder at the desired spacing. Built in voltage regulator eliminates the need for a voltage dropping resistor. PCB dimensions are 3"W x 2"D.

Loop features adjustable Send and Return levels that can be adjusted externally through the jack once installed.

Installing this module will require you to work with high voltage. Previous experience with tubes and/or tube amplifiers is mandatory. It’s recommended to have the module installed by an amp technician. Please use shielded cable for input and output.

Please note! The latest version is 4.2B, Functionality is the same as previous versions but has an improved noise floor and a flatter frequency response.

Some components may also vary due to availability but will be of same quality and specifications. The input jacks will always be Neutrik. All modules are made and assembled in the US.

The ground points next to the IN/OUT are for the shielded cable ground and it should only be grounded on this end. Latest version is on the pictured marked "shipped items".
