There is one left in the batch if anyone else wants one. This one has a slightly higher gain for Q3 (110)

And then no more ever (from me at least)...

With only one left I can do these for USD$100 for everyone plus your choice of shipping. If you are on the 32OD list as well I'll ship both pedals in the same box.

Hey Laurie.

Are you planning to put the power switch Sclitheroe requested on all of them or just his? If the latter, would it be possible to have one on mine as well please?

No worries! I ordered switches for all the pedals and was going to put them on all ;)

A pedal mobile...

This paint will take maybe a week to fully cure. Then labels and clear-coat.

After the clear-coat has cured, final assembly and test.

Based on the bias discussions on the previous page, I've made a small adjustment to the schematic. I've removed R6. R6 was there to limit the maximum resistance of the bias trimpot to 20k as recommended in the link at the start of this thread.

The reason I used a 50k trimpot and a parallel 33k resistor to simulate a 20k trimpot is that there weren't any 20k trimpots in stock at Mouser...

It turns out that this was serendipitous... Removing R6 gives the full 0-to-50k on the trimpot for the bias which is more useful.

The holes for R6 are still on the PCB, but R6 isn't there. When you receive your pedal, please be aware that this isn't a defect...
