Meatball/ McMeat Voltages

[hendrix2489]

Hello,

i was wondering if i could get some voltages for ic1 and ic2 on the meatball project.  i am using joep's layout, but i am using the layout with the on-board switches. 

i dont have time right now to take voltages.  the effect bypasses, but with it on i get a stationary wah sound, sounds like a wah, and with some of the pots i can make it wah.  It seems that vr1(Sens),vr6(blend) are not working.  i have put leds where the vtls go and in place of rotarys i put flip switches just to make it ez-er for me. i get the leds to brighten and dim with the pots but i can not get them to pulse.  also it seems that sw1(band) does not do anything.

any help would be fantastic thanks

The Mcmeat can be a debugging nightmare. I would suggest first checking that the rotary switches and any off-board wiring have been implemented correctly. The bugs that occurred during my build were centred around the wiring of the switches because it's so easy to get it wrong, even with the on-board switches PCB (which I didn't use because I wasn't convinced it had been fully verified or at least was unsure of which was the final version). It might be a good idea to check your PCB against the original schematic to make sure you agree with how the traces to the switches have been implemented vs the schemo. Also, have you routed the effects loop part of the board correctly? It's a good idea to route this directly using some hookup wire from send to return pads on the board while getting everything to work, then add the send and return 'normalled' jacks once everything is good.

yes i have checked the board to the schematic in joeps pdf, thats what i used mostly.  Yes i also jumped the send to return pads on the pcb. 

thanks ill check out the offboard stuff in a little bit.
