Hi folks,I have a guitar synth that is acting strangely.Did the internet searches for the usual suspects and eventually came across it's "service notes".In the "notes" which doesn't cover much I found that the unit can perform some self tests so I ran them and believe it was test #3 that it did not pass.Anywho the test is to check midi output(the unit acts irratically ,sometimes some strings won't sound,sometimes they all do,but the vol is always so low that I have to run the the guitar and the amp almost wide open and it's still not enough volume).The service notes do list 2 ic's to check but I cannot locate them on the block diagram or the parts list.there are not a lot of ic's in this(maybe 10)so I am wondering if there is some way to check the ic's in this unit and maybe find the culprit.Must warn you that I know next to nothing about electronics(I do have a multi-meter tho if that helps.Also my brother does electronic repairs but he is very busy guy so seeing if I can sort this myself.Appreciate any info or advice,thanks,Glen.
