GermanDescription
The Monad Vintage Boost is an adaptation of the Univox Uni-Drive UD-50. Since the rotary switch was set up as a potentiometer with six fixed positions, in this project it has been converted to an actual potentiometer. And since the range control is only needed for a treadle, it?s been omitted and merged into the output volume control.
Along with those changes, two modifications have been added. The first is an input capacitor blend control, allowing you to reduce the bass content for more of a treble boost than full-range. This is a common modification for vintage pedals with no tone control, often seen on variants of the Fuzz Face and Dallas Rangemaster. The second modification is an internal trimmer that allows you to adjust the amount of feedback from the third stage back to the first stage. The default resistor is 8.2k in the original, but by setting it higher or lower, you can get some interesting tonal changes.This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 3 knobs for 6,3mm shaft separately.

This project is by Aion Electronics, in collaboration with Musikding. If you have any problems with the contents of the kit, please contact Das Musikding (Klaus). Since the modifications require some basic knowledge, this project is rather for more experienced builders.
