Aside from the fact that Pat Metheny is not dragging a G-808 out every night, the G-808 guitar seems slightly neck heavy when compared to the G-303.Also, vintage guitar synth guru Rich Hilleman has suggested that the through-neck design of the G-808 adds to the resonance of the guitar, making the G-808 less suitable as a synth controller.

In Los Angeles I have seen jazz players using the G-303 plugged straight into a Polytone amp, just for the sound and playability of this great axe.In addition, the standard 1/4” output jack solders directly to the PCB, rather than the ribbon connector.The first time I tried to repair a failed op-amp in a G-303, I realized that the pin-out documentation was wrong on the schematic.Capable of both enchanting clean and raucous overdriven sounds, the signature chime of the AC30 Custom pairs seamlessly the intricacies of your playing style, resulting in a sound that is truly your own.Perhaps the most iconic amplifier in VOX’s pedigree, the AC30 earned its place in history as the amplifier that powered the British Invasion.

The pin out information was correct on the G-505 Service Manual Schematics schematic, which uses almost the same circuits.All the G-303s and G-808s that I have checked have op-amp pin outs consistent with the G-505.More about the Roland G-303: Features and Specifications Introduction Links Versions - PC Boards Versions - Synth Pickup G-303 and the Synclavier Photos - Brown Finish Photos - Left Hand Photos - White Finish Photos - Elliot Easton Blue Photos - Breedlove Mark II Synergy Videos Origins of Roland Guitars Modifications Schematics - Service Bulletins - Repairs Repairs - Opamp Failure Repairs - Synth Pickup Dating Guitars Body: Maple top mahogany back Finish: Acrylic ("robert" brown or white) Neck: Set-in 3-piece maple Fingerboard: Rosewood Frets: 22 Bridge: Fixed, adjustable Nut: Polycarbonate Tuning machines: Gotoh Pickups: Two Roland PU-114H Humbuckers Scale: 24 3/4" Truss Rod: Adjustable Neck Width: 1 11/16" Body Width: 13" Body Depth: 1 3/4" Overall Length: 38 3/4" Weight: 8 lbs 8 oz.If there is one guitar that has become the "gold standard" of guitar synthesizers, it has to be the Roland G-303 guitar.In terms of sophistication of design and electronics, the weighty Ibanez IMG2010 comes out way ahead of the G-303, but like the Roland G-707, the IMG2010 is a bit of an acquired taste, and its curious body design means that the Ibanez IMG2010 is virtually impossible to play sitting down without a guitar strap!

The other vintage controllers, the G-202 and G-505, are well-built, fine guitars.Which made me wonder if the op-amp information in the original G-303/G-808 Service Manual Schematics refers to the very rare "version A" board.It is difficult to see in the photos, but on the standard cards, version "B" and "C", three op-amps, IC1, IC2 and IC3 are used to amplify the signals to line-level for the GR-300.1982 Roland Product Brochure - Japanese - Featuring the G-303 and G-808.1982 Roland Product Brochure Featuring the G-303 and G-808.
