The Effects Loop Interface is Two-Rock's buffered box for running outboard effects through any amp with a passive effects loop. A single 12AX7 drives it.
Long chains of pedals and long cable runs load down a passive loop and lose top end. The interface buffers the send and return so the impedance mismatch goes away, and a bright switch on each side puts back any high end the chain still costs you. Send and return levels are separate.
It's built for amps with a passive loop, like the Classic Reverb Signature, Traditional Clean, Studio Signature, Burnside and Silver Sterling Signature, and works on other makers' amps with a preamp out and power amp in. The TS1 and Studio Overdrive already have tube-buffered loops. This listing is the 120-volt version.
