Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

My apologies. I did not "as stated" say I reset it.

Well, I have taken it apart to test the actual switches. They all have reflex, but I still have the problem. The real difference is that if I don't hold button 1 when I power it up, the little Digitech emblem cycles then disappears. When I hold button 1 and start it, it flashes to an asterisk. Still no joy.

Also- when I hold button "2" and start it I get the "Digitech Crew" scrolling across the screen. So the ROM is working. (Ron Baker, Mark Greenhalgh, Jim Pennock, Wayne Moss, John Louder, Brian Pett, Jason Lamb, Billy Clemments, Randy Thorderson, Brian Write, Rob Urry)

I took it apart (face plate and display board) to clean the switches. I did continuity test and all pins on all switches have continuity. All the plastic switch covers are working. Looking at the schematic and the pcb, all pins should have continuity with any ground source. So, I'm going to have to check each state on each switch. I'm not ruling it out, but I don't think it is a stuck button. (maybe a bit more deoxit...)

None of the caps are bulging or leaking (doesn't mean they haven't gone bad)\ufffd and I don't see any bad soldering joints but I haven't flipped the main board to look there. Too much work unless I wanna replace all the caps or something.

Im putting it to rest for the night. I'll get back on it tomorrow sometime.

Thanks for your responses though!

I can't find where you said you performed a reset, but I'm pretty brain dead these days.

GSP 2101 ver 1.03.02\ufffd (pre Artist series)

Anyone run into this-
I am messing around playing or programming and after about an hour I get stuck on whatever patch I'm in at that moment. I can keep playing, but I can't change to another program. I turn it off, then back on and I get the boot screen where it just sits. I can't make a noise at all.

So I let it sit for an hour or so then it works again.

I am thinking that there is an overheating issue. Here is what I know:

I opened it up a few days back to check the EPROM numbers so I could order my Artist (ver 3) upgrade. While I was in there I checked the visible soldering joints, made sure socketed chips were tight, pulled and tested the tubes (which are normal).

I didn't see a fuse in there, and I don't see one on the schematics. I got the MIDIWizard program installed and configured and was able to pass the 2 loop tests while the unit was in it's locked up state, so I *think* it is a problem in the bus/ram/CPU area that's not visible. (I did order the 20Mghz processor upgrade as well, maybe that fixes it...)

So.. Anyone here run into similar issues and know the fix?

Thanks
