Pez 90 - Phase 90 - distorts

[Luqqas]

Hi there!

I've made Pez 90 from Tonepad. Phasing is correct, only that general effect level  is low and it distorts a little bit  if one hit strings normally.

I've tried changing the 150K resistor between base and collector of Q5 (put a 2N3906 with 250 hFE) as is indicated, but still distorts.

Any help?

"What to do when it doesn't work" , plus what kind of guitar, any buffers or boosters between guitar and P90?

Thanks, R.G. I know that article. I've read it.

Using an SG, no buffers and booster in between.

Publish voltages? I' ve founded pretty much correct, except that the reference voltage setting by 250K trimpot is 2.3V.. appears to low. And searching for another build reports on this forum, others stated 4.3V and similars

The real question was "big guitar signal?", which could be from humbuckers, or some other pedal making the signal level bigger.

That is low. The question is - why? That's one of the likely causes that made me ask for all the voltages.

Need a schematic, layout and Lets get some pics!
