Troubleshooting
All PCB’s have been
100% factory e-tested and out of every batch I receive I build an effect to double
check, so there should not be a connection problem on the PCB itself.
The board is not working (at all), what now?
•
Check if your 9V is plugged in correctly (and/or soldered correctly on the board). Pay special
attention to the polarity.
•
Check that you oriented
the capacitors, IC’s ,transistors and diodes the right way.
SMF, MKT
and ceramic capacitors as well as resistors do not need to be oriented. A likely sign of
incorrect capacitors and/or orientation is when an effect is sputtering, rumbling or
“motorboating”.
•
Check if you used the correct values of the components. For resistors you can look here:

•
Double and triple check your soldering! A loose or cold solder can be really bad for your
board.
•
Replace the IC and/or transistors, one might be defective. Before doing that first unplug the
9V and wait for 5 seconds.
•
Check that you have good/high grade components. A lot of Chinese sourced parts are fakes
(especially high end opamps, audio capacitors, vintage diodes and transistors) so be careful
that you source your parts from reliable suppliers.
