Never Worry About Your Bass Tone Again!
The Damnation Audio MOSFET Bass Distortion or “MBD-1” or simply “MBD” was originally intended as a distortion pedal for low-tuned high-output basses. I searched long and hard for a pedal that could get me the smooth distorted bass sounds I heard in other people’s rigs but without having to sacrifice my ape-like pick attack in Drop A# while pushing an unreasonably high output signal. I couldn’t find it so I had to build my own.
Gain: Controls the amount of input gain of the distortion channel.
Level: Controls the output level of the distortion channel.
Tone: Tilt-style tone control for the distortion channel centered around 300Hz or 600Hz depending on position of “Shift” control.
Shift: Down position centers the “Tone” control at 300Hz with about a 10dB cut at the center frequency. Up position centers the “Tone” control at 600Hz with about a 6dB cut at the center frequency.
Clean: Controls output level of parallel low-passed JFET boost channel.
Depth: Controls the amount of low end injected into the distortion channel. Less depth for a brighter tone and more depth for a thicker tone.
Boost Trim: Internal trim pot (left hand side when looking at the PCB) which controls the amount of input gain to accommodate a wide range of basses. Boost range is from 3dB to 29dB of boost. Set at the factory at around 9 dB boost which works well with most basses.
Bias Trim: Internal trim pot (right hand side when looking at PCB) which controls the bias of the parallel JFET boost channel. Set at the factory at around 5V for the most amount of clean headroom.
Use only 9VDC 2.1mm center negative (boss-style) power adapters. Isolated pedal specific power supplies are highly recommended. Damnation Audio pedals are designed for maximum headroom and ideal performance with a 9V supply. Going above 9VDC will damage your pedal and void any warranties. Damnation Audio pedals do not accept 9V batteries.
