|
| G-202 |
 |
The G-202 has a unique, stripped down hex-fuzz circuit with less sustain. However, this guitar was paired with the Roland GR-100 which is essentially a "super" hex-fuzz synthesizer. |
| G-303 |
|
The original G-303/G-808 schematic had incorrect IC notation! This schematic is the corrected version and identical to the G-505 and LPK-1 schematic. |
| G-33 |
|
Precision-style bass designed to work with the Roland GR-33B Bass Synthesizer. |
| G-505 |
|
Vintage Roland Guitar synthesizer electronics, with hex fuzz and touch pad logic electronics. |
| G-707 |
|
The G-707 was the first guitar introduced without hex fuzz. This made the electronics card smaller and easier to fit in to the unique design of the G-707. The STK-1 is almost identical, except the G-707 has buffered electronics. |
| G-77 |
|
The G-77 is the four string bass version of the G-707 guitar. Thanks to Pablo Leocata for this schematic! |
| G-808 |
|
The original G-303/G-808 schematic had incorrect IC notation! This schematic is the corrected version and identical to the G-505 and LPK-1 schematic. |
| G-88 |
|
Precision-style bass with through-neck construction designed to work with the Roland GR-33B Bass Synthesizer. |
| GK-1 |
|
The GK-1 is the only Roland schematic that I have that was not hand drawn! Roland moves into the modern age with the GK-1 schematic! |
Ibanez
IMG2010 |
|
The trim pots work differently on the IMG-2010. Rather than trim the output from zero to full, the trim pot works from half to full output. This more useful range makes for easier adjustment. |
Korg
ZD3 |
|
For more information on the ZD3, check out the Korg Z3 web page. The ZD3 should work with any Roland synth, but I have not personally tried this out. |
| LPK-1 |
|
This LPK-1 kit has the exact same electronics card as the G-303, G-505 and G-808. |
| STK-1 |
|
The STK-1 kit is the exact same electronics as the Roland G-707 electronics. |
