These op-amps are the top three 4558 op-amps in line with the 24-pin ribbon connector.
If you look at IC6, at the top of the version "B" and "C" card, you can see resistors just to the left of the chip creating gain in the negative feedback loop, and additional diodes just to the right side of the chip for generating fuzz. After years of working with Roland vintage electronics, I finally noticed that there were two variations on the familiar hex pickup.One of the top 50 models on Models.com, he has worked for talents as far and wide as Alexander Mc Queen, Yohji Yamamoto, and Karl Lagerfeld.He’s also appeared on the covers of English comedian and actor Stephen Fry, 57, married self-styled comedian Elliott Spencer, 27, in a quiet ceremony in Norfolk on January 17th.Generally, the narrow pickup seems more common in earlier guitars, and the wider pickup is common with the later models.I had been exchanging emails with GR-user Jonathan Prince, who had, once upon a time, ordered a replacement hex pickup from Roland. Mark Wire, it lays out all the technical information on the pickups that I had only surmised!There are some ideas as to why the more expensive, classier G-808 never quite took off with the same following as the G-303.
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.
If there is one guitar that has become the "gold standard" of guitar synthesizers, it has to be the Roland G-303 guitar.
No doubt much of the popularity of the G-303 comes from Pat Metheny, who has played this guitar year after year on stages across the world, always amazing audiences with the moving and emotional quality of the G-303 and GR-300 rig.
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.
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.
