MI Audio Blues Pro Overdrive
Posted Fri, 2009-11-27 21:32 by Harold
Project description
Based on an unverified schematic of the famous Blues Pro overdrive found at Freestompboxes.org.
I'm not very proud on the small space for C4 but in the schematic C4 was an electrolyte with a way too huge value: 22uF. 220nF is the correct value for C4.

Just Right!
Submitted on September 4th, 2012 by AnonymousThis was just the overdrive I was looking for. Had to do a little troubleshooting while trying to stuff it in with another effect. But it didn't take long to catch my own mistakes. This thing sounds awesome! Marsh@ll who???
