Title: King Slayer 2015 - LED Clipping Tone
Post by: strat56 on September 01, 2016, 09:16:19 PM
Me again, I recently finished this King Slayer 2015, had two problems, volume control didn't work and LED clipping sounds flubby.  I reflowed the solder joints on the volume control and it works now but the LED clipping is still flubby, very bassy and not very pleasing at all. 

Pics attached, any ideas anyone?  Did I use the wrong LED's?  I didn't have any square ones like in the build pics in the build doc.  This is fun but I wish one would just work right the first time :)

Thanks in advance for any help/suggestions.

What you are describing sounds like either one LED is in the wrong way or it is shorted to ground. Check to see if the LEDs are arranged back to back (can't tell from your pic). If you have a continuity checker, see if either LED has both ends connected to ground (which would indicate a short).

Is there contact between the back of the pot and the diodes? That could be a culprit.

I looked for a flat spot on the LED's to make sure I had them in right but couldn't see one.  I'll check that out.

I 've checked for that but maybe I'll stick something in between that pot and the board to make sure.

On them dual pots I use sticky double sided foam pads 18mm size seem to be good.
