I had originally intended to sell my AD50VT-XL for the 100-watt version (which has an FX loop). But after two weeks on a selling thread, no one was buying, so i decided to take matters into my own hands:
The mod was done by Raul Q, a straightforward loop insert just before the master volume (ala Fender). The hardest part was the drilling on the chassis (for the jacks) and finding the exact place on the PCB to cut and attach the shielded cable.
Unlike some US-based mods, this loop doesn't sacrifice the stereo headphone outs, and allows the effects loop wet signal to be heard at the recording out. Just remember: this is a line level loop, so instrument level effects might cause a volume drop. Plus, this mod WILL definitely void your warranty, so wait a bit if your amp is brand-new.
