Operation Manual

Engaging this switch reduces the input signal by 15 dB to reduce potential distortion on the input when
using active basses or passive basses with particularly hot pickups.

to accentuate highs above ~3 kHz or to emphasize high-end response.
When engaged, this switch activates the overdrive mode of the preamp.
