Stone Deaf's take on a Maestro MPF-1. I added a Volume control since this thing gets loud. I also omitted the expression since a volume pedal with custom made dual wah pot is required.
Schematic is avaiable HERE.

Great work! Been wanting to build this for quite some time but wow that’s a lot of off board wiring!
ReplyDeletethat's a big layout! believe I've found two faults (if it's only two well done!)
ReplyDelete-Both 1k6s are connected to pin 7 of IC4, I think one should be connected to pin 6 instead?
-There's a missing 100k to ground after the final 100U (before level 3)
Yep, one of the 1,6k's should go to pin 6. It is now fixed.
DeleteVolume control replaces the 100k resistor at the output.
of course with the 100k.... doh!
DeleteThis ones on my list to do, hopefully in the next week or so!
keen to see how you go Chris. Massive QOTSA fan and always wanted to build this but have heard very mixed reports. Layout looks brutal haha.
DeleteBuilt and worked straight off! Ton of wiring...just take your time and preplan it before you do it. It's ok! The bandwidth drastically alters how height and frequency work so you have to get used to that, and height at noon means the pedal does nothing, so don't fall into that trap!

ReplyDeleteBuilt, all working! You can tag this as is.
ReplyDeleteAwesome, great job!
DeleteWill tag it ASAP.
