Granger Amplification is now offering our new high voltage, zero-loss, true-bypass effects loop in kit form. Our Ultimate FX Loop works perfectly for most vintage Marshall, and Marshall-style amps, as well as many other modern amps, that have extra mounting space in the chassis. Optimized for insertion between preamp and driver stages, our low noise, non-clipping, analog effects loop utilizes a discrete, high voltage buffer and a return gain stage. To be the most compatible and easy-to-install effects loop available, we made the mounting requirements simple (4 wires - Power, Ground, Signal In, and Signal Out), and also features internal trim (level) pots that can be accessed directly through the jacks (no removing chassis) using a small flat-bladed screwdriver. The footprint is small (3 holes), yet both the send and return levels can be adjusted for nearly any loop requirement. In stock configuration the send stage has 10dB of cut and the return stage has 16dB of gain, for a net gain of 6dB. Low cost stomp boxes and pedals work just as well as thousand dollar rackmount effect units. The Send is configured as non-interrupt, so it can be used as a Preamp/Slave Line Out. We also made provisions on the circuit board to wire in a separate Line Out should both be required. The board can easily be mounted component side up (Send jack on the right when the amp is upright), or solder/trace side up (Send on left), with power, ground, and signal terminals clearly marked on both sides. We also offer the option to have the bypass switch mounted to the circuit board (default), or included separately as a panel mount switch, if an alternate mounting location is desired (Selectable from the dropdown below).
This is the most versatile effects loop on the market! Instructions, drilling template, wire leads, and recommended wiring examples are included.
Board dimensions: 3.25"L x 1.75"W x .880"H
Send, Return jacks spaced: 1.5"
True Bypass switch centered between jacks (default)
Operates from existing B+ supply (200-400VDC)
Shielded cable (RG-174) is included for shielded signal wiring (Send, Return)
Power wire leads are 1 ft. sections of 22Ga TopCoat 600V in Red and Black
