Just finished building this and it works, but I ran into some issues.
It oscillates without a buffer in front, and the volume needs to be set at around 3-4 o'clock before it reaches unity gain.
There's also a slight ticking noise when the gain is set too high.
Though, I substituted a bunch of parts to build it, like using transistors as the diodes, so I might try and rebuild it with proper values to see if the issues remain.
Alright, finally got this working properly. The layout uploaded here was based on a previous schematic for the hard bargain which had some issues according to Electric Druid.
To get it to work properly, I took out the 22nf caps, and swapped them with jumpers.
Next, you need to make some cuts on row F and row G so you can place the 22nf caps right where the 10k and 1k resistors meet.
Sorry if it sounds confusing, just check the schematic available online and it should be easier to understand :)
The switch is also optional, the v5 schematic took it out completely, so you can just put a jumper wire there if you don't want the switch.

NVM, the ticking was cause of a tremolo pedal in my chain.
DeleteOther than the low (but still very usable) volume and the oscillation (might be an issue on my end as it happens with other pedals) it works great!

Thanks! Great work! While looking at v5 schematic I found some other tiny changes so I had to shift some things around but connections is the same.
DeleteI al so did this and it works perfetto,so it's verified.thanks fuzzhead.
