With the Drive knob cranked, the RB-III produces a natural, crunchy overdrive reminiscent of the classic guitar tones of the early 70’s yet remaining faithful to the original amp tone frequency spectrum.
The RB-III improves upon the popular Rust Booster I circuit by increasing the range of the distortion, allowing for a wider variety of tones. In addition, the amount of output has been increased, making the RB-III perfect for use with low-output pickups. Bass players will love the RB-III for its ability to boost bass signals without sounding thin or muddy.
