Version 1.0 2024
The Beverly BitCrusher uses an analog-to-digital converter to turn the
signal into a true 8-bit representation. You can change the sample rate
from high to low - clean to crushed. It also has a blend control so that
you can mix the crushed sound with the clean guitar signal.
Have fun building and playing the Beverly BitCrusher!

- Page 3 General building tips • Just follow the Bill of Materials and solder the low profile components first. Recommended order: resistors and diodes, chip sockets, resistor ladders, trim pot, multilayer and ceramic capacitors, film box capacitors, electrolytic capacitors, pots and switches, offboard wiring (jacks and the 3PDT switch).

This template is approximate. • Make sure your printer isn't doing any scaling (100% print size). • Jacks are measured from the edge at the front/top of the enclosure (as they were drilled on the prototype), but you can drill the positions for the footswitch, DC jack and input/output jacks to your own preference.

Take your time and don't rush. Take a break now and then. Use good solder, and it helps to have a decent soldering station insted of a cheap iron. If you are still having trouble, please visit the madbean forum Parasit Studio subforum section and ask for help there. http://www.madbeanpedals.com/forum/index.php?board=84.0 If you have bought the Musikding kit and have recieved a faulty or missing component, please contact musikding directly.
