Does anyone know where I can get a schematic for a Roland GI-10?
Thanks,

Here is a little bit of the power section.

I haven't run across a full schematic. I own a GI-10 so if you need to identify a blown IC or anything like that I may be able to help.

My unit actually works OK. I 'm looking for a schematic because I want to modify it so I need to get a look at the input circuitry for each string.
Thanks.

OK - then I would recommend taking a look at the GR-30 service notes because there's a good chance that the input sections are very similar.

You can find one here: http://www.synfo.nl/pages/servicemanuals.html

The input sections probably are similar but I need the proper schematic to identify the entire buffer chain and conclusively know which IC carries which signal path at each point in the chain.
Thanks,

Only official Roland repair centers obtain these now
start there

I called Roland but they only release schematics to authorized repair centers. I was an authorized repair tech for years and had access to schematics from every major manufacturer but I moved to LA and have been working in studios for 20+ years now. Since I'm no longer a bench tech I'm on the outside of that world now. I really miss access to technical documentation.

Just saw Bill's response, I'll PM you. Thanks so much!

Does anyone know if the Guitar signal pin 7 is used anywhere in the GI10, or is it available to hijack, or for that matter pins 8-11?

AFAIK

GI-10 has no connection to Pin#7 (Normal Guitar Out)



While the updated Roland GI-20 does provide a Normal guitar output on rear
