I have included the Buff n Blend on almost any build where I can fit it to make as many of my builds as possible more bass…Read more

I had quite a few in this batch of pedals I made, must have flown too close to the sun (trimmed too close to the board).
Anywho, this build still rocks and is a (not so) secret shoegaze machine for those of us who long for blown out, wall of sound-esque tone.

The PDF should be Tayda ready as is but let me know if you have any issues.

Decided to lean into the godfathers of metal by recreating the Master of Reality aesthetic while incorporating the art from the Sabbath shirt I had when I was 16.

Only tiny tweak I made was squeezing in an order switcher as I…Read more

Re-flowed all joints on the phaser and replaced all capacitors, both transistors, and a couple resistors. After reflowing I put a little rubbing alcohol on a toothbrush and brushed around to clean up some of the flux and any possible bits of stuff that could bridge pads.

I have left the pots…Read more

Went back through checking continuity and found a cut trace between +C8 and -C9 but repairing that didn’t solve the problem.
I checked components with a multi meter and visually against a picture of a working build of the DSOTM that I did last year. The only difference is I used…Read more

Planning to try more from a different supplier and see if that is where my issue lies.

Tested another build of the same pedal I was doing simultaneously to the same issue, i’m wagering it’s a component/orientation issue. Will check everything again and circle back.

if it’s helpful at all the LED immediately lights up (without strobing) as soon as Q2 is inserted, regardless of the status of Q1.

Removed sockets and soldered transistors directly to the board with the same results.

Everything seems to be working fine other than the phaser. The effect is passing signal but it isn’t phasing. When looking at the LED it just remains on and doesn’t pulse. All controls seem to effect the signal appropriately with…Read more

I’ve got the voltage sitting around -8.5v with no volume loss. Sounds absolutely wild.

The gain pot was a little funky so I replaced it then was able to fine tune the Ruetz mod where I think some of my high end frustrations were coming from.

I started by going for the same configuration i had on my last couple builds (1K trimmer, 100ohm in R7) but…Read more

Replaced the diodes and re-flowed every joint.
Circuit is still generating tone when enabled. When I pop the opamp out the noise stops (i’ve tried multiple op amps) which leads me to believe the problem is in the gain stage. I’ll keep working on this and follow up when I have more updates.

First off, when I engage the circuit the volume drops a significant amount.

Additionally the closest I can get the bias to the recommended -7v is -5.46 with the bias pot turned all the way counterclockwise gets quieter/less fuzzy as i turn it up. I hope it’s not a…Read more

I shot you an email with a couple small edits otherwise but what you’ve got is pretty comprehensive. The biggest thing is just double and triple checking every step in the process.

More related to the pedal, I found a decent Smashing Pumpkins Siamese Dream–esque tone by diming out the Wattamp…Read more

It’s Tayda ready and should line up perfectly with Barry’s drill template.

Super proud of how the print ended up turning out and the classic knobs really pull the look together.
