Here's a few more that I've been working on. First are 3 more Violet Rams Head BM's built on gruntboxes, such an awesome MB/CJ collab! I still have a nice stack of them
I wanted to try and build 3 of the same pedals w/ different caps, see if there was a huge change in tone between them. I used green Mylar in one, cheap-o ceramics in the second and poly film box caps on the third one. All the ceramics (.1uf) read in the .08-.09uf range so they were maxed on their tolerance. The rest measured out pretty close to what they should be. They were all very close with the ceramics sounding a bit more treble-y. While they all sounded great individually, there is just something about the one fitted with poly film caps. It made such pleasant sounds to my ears.
They all have Q1-3 emitter resistors bypassed, limiting resistors increased (think I'm gonna make them higher on the next builds, 15k-22k), mids knob added and tone stacked is slightly tweaked. The box cap version is for a very special doom metal guru, who I met this past summer and am quite excited to hear what he has to say about it.
