Started troubleshooting my FU-3 last night.
we have determined the cable is fine, so now we are thinking it's the chips on the board
I used this thread for reference: http://forum.grailtone.com/viewtopic.php?f=3&t=30607
we tested the pins on the logic chip for power but did not get the appropriate reading (once again, per the thread above)
The LED's on the footswitch work for the loop and eq switch (and those switches work) but no LEDs nor any channel switching from the channel buttons.
is replacing the chip my next step or is there something else I should look into?
does mesa supply these chips?
