question: should the two green leds in the yellowshark light up when powered ?
No. You might see them light up slightly when playing hard, but with no signal, they shouldn't light up.
thanks !
How about this one:
I am getting a lot of hum, but i hear the effect perfectly.
-if i dont connect ground to both in and out jack i get no sound and loud hum. However, when i connect both jacks to ground, i get the effect but with some hum...
-I see madbeans' drawings on how to wire up the switches and jacks, where he leaves the ground off the output jack but connects ground to input. this scheme doesn;t seem to work for me. what can i be doing wrong here ?
any thoughts ?
Depending on the jacks and enclosure you use, you may or may not need to connect the jacks to ground. The enclosures and jacks I use all conduct and become ground. This means I only need to connect the ground of the pcb, switch and dc to one of the jacks - the other jack connects through the enclosure.
Hum can come from many places. You need to figure out where it's coming from.

yeah, this was a "duh!" moment. I dont have this in an enclosure yet. so - i bet when i wire the jacks together by the same ground i am getting the hum from a ground loop... i will put this in an enclosure tonite and stop being so dumb
Thanks !
