Sorry, I had a wedding in Finland this weekend, so I just came home. Hope to check it tomorrow as I haven't slept in days.......... 3 days of beer, Finnish women and sauna

Looks to me like it is a 100K on the jack side of the .22uF output cap. "Anti-pop".

Yes, that was it! I added it to the unit's notes underneath the picture. There is a 1M resistor used as a pull down on the input.
Now, do we miss anything?

The ones to the volume pot sets the volume range. The volume can't go to absolute 0, the other one attenuates the signal a bit.
Mine doesn't have those.

Nope....... maybe I misplaced the potmeter but it works in the normal waypf_fan wrote:Bernardduur, On your schematic "Gain" pot is 2k2 linear (labeled 2K2A) and wired backwards compared to original schematic (10k log). Is it working backwards too?
Not that it adds that much. More like on 95% suddenly the gain kicks in

2K2A is actually a log pot. Which would explain why all the action takes place at one end of the travel ?pf_fan wrote:Bernardduur, On your schematic "Gain" pot is 2k2 linear (labeled 2K2A) and wired backwards compared to original schematic (10k log). Is it working backwards too?
I think patafix is right - look at this picture:Torchy wrote:2K2A is actually a log pot. Which would explain why all the action takes place at one end of the travel ?
It's 2k2A but there's LIN written next to it...
And a small collection of various Gain/Volume pots from Power Boosts/Overdrivers (both vintage and reissue):

Youre right, sorry - I just read the 2k2A code.
Those look like Omeg P16's :- european made so they follow the european "standard" of A=Linear, B=Log. Total pain in the arse when the rest of the world follows the USA standard A=Log, B=Linear so why they go against the majority of manufacturers beats me. Typical european arrogance I suppose. Having multiple "standards" for the same thing seems an oxymoron to me.

This is NOT US-standard, this was "invented" by the Japanese.
And the "european standard" was invented long before that - by Radiohm. And it would make more sense: Standard is linear so "A", logarithmic gets "B" and Rev.Log gets C.
Only some stupid guys couldn´t keep this in mind defined logarithmic as "A" - like "Audio Taper".

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

Hi,
I've seen various layouts, or could breadboard etc,
but does anyone know if ready made PCBs for this FX are around ?
Thanks

Can someone give me an advice??
The Overdriver Schematic has three 25uF caps, but I can only find 22uF and 27uF caps... Which value should I use?
I´m going to use these files for my project:
Has anybody verified this??
