Thanks for the reply!
Oh yeah, I'm fully aware of the battery issue and I've done plenty of
retracing around IC31 and have fixed many of the major problems. I was
just hoping to get some specific info to help accelerate the process.
But, I have the schematics now so that'll help quite a bit. And I'll
take your advice and do some searching. I already had a good read
through of some of the more recent posts and found some invaluable
info in there.
Is it necessary to replace the IC's if the traces are being taken care
of? it ∗looks∗ like it's in good shape, but I guess looks can be
deceiving.
I will also note that the Effects section seems to be working just
fine now.
