Hey guys just finished up an ibanez tube screamer 808 symmetrical clipping clone but the thing doesn't make any sound when the effect is engaged. When in "bypass" mode the guitar goes through but it's when I turn the effect on my pedal light comes on but the sound is completely dead! Can you guys give me help on debugging the pedal as far as checking op amp voltages and other ways to check my parts.
Thanks!
