The ideal companion for your Effects Loop!
With the Two-Rock Effects Loop Interface, you no longer have to sacrifice your tone when using outboard effects.
Passive effects loops can create impedance mismatches, leading to weakened tones—especially when multiple effects or long cable runs are involved. The Two-Rock Effects Loop Interface solves this!
It's the perfect companion for any amp with a preamp output and power amp input jack.
Designed with meticulous attention to detail, this all-tube full-buffered interface ensures that your signal remains crystal-clear as it passes through your effects chain.
Whether you're running modulations, delays, or reverbs, the Effects Loop Interface preserves every nuance of your sound!
Take full control of your tone!
The Effects Loop Interface is equipped with two main stages to keep your sound pristine.
First, a high-impedance 12AX7 tube buffer provides up to +20dB signal boost with a bright switch for added clarity when needed.
Your signal is then sent to your effects.
The returning signal then moves through an additional buffered tube stage, with level attenuation control and a second bright switch.
Virtually any rig will benefit from the Two-Rock Effects Loop Interface!
