I just had one given to me a few days ago & it seems to be  Flanging on only HALF the cycle.  :(

Does anyone have a SCHEMATIC? this would help trace the signal path & troubleshoot better.

I searched the internet & couldn't find any free schematics for this model = M-152 (2 knob)
The only one I could find was the M-117 (4 knob version) which is much different.

Also, Does anyone have any experience with THIS Pedal or know if they sound any good... & are worth fixing?

*What I've done so far:
Checked & changed ALL electrolytics & Tants.
Checked all wiring & Pots

IC in this Pedal are:
SAD512D
MC14069UB
TL062CP
TLO61CP


Thanks in advance.  ;D

I did try adjusting the trimmer & it changed things but didn't have any effect on the "missing" half of the cycle.

I'm not sure what the voltages should be at the critical IC, etc...
Having a schematic would help. :)
