Roland G-33

Introduction to the Roland G-33:

The GR-33B was packaged with the G-33 or G-88 bass guitar controller. Like the G-303 and G-808, the basic design of the bass guitar is the same for the G-33 and G-88.

The G-33 and G-88 electronics package has master volume and two bands (high and low) of active equalization. When connected to a Roland guitar synthesizer, the active electronics are powered by the synth. When used alone, two nine-volt batteries supply power.

The G-33 has a rosewood fingerboard and set-neck construction. And, like the G-303, the G-33 has nickel/aluminum alloy nichrome plated hardware. The 1982 Roland guitar synthesizer brochure notes that the G-33 has a Roland PU-144S single-coil pickup.

The G-33/G-88 bass guitar, like all the vintage Roland guitars, was built by the Fuji Roland corporation, a joint venture by Roland and the Fujigen Gakki. Fujigen Gakki (now known as FGN guitars) also made the Ibanez guitars.

1st string (G) - 44

There are two versions of electronics cards for the Roland G-33 and G-88 basses. The most distinctive difference in the two cards is the placement of the string level trim controls. On the early basses, the trimmers are placed in a verticle alignment.

On the later cards, the string trimmers are placed in a horizontal alignment. Otherwise, the actual circuit designs appear to be the same. The Roland service manual notes that basses with serials numbers 040500 and later have the horizontal trimmers, and serial numbers 030499 and lower have the verticle. Basses in the range from 030400 - 040599 could possibly have either electronics card.
