SBC-1324 Roland 24 or 13 Pin Input to 13 and 24 Pin Output
Back in 2009 I was approached by a very talented Canadian guitarist who wanted to be able to control both vintage Roland 24 pin GR-series synthesizers and modern Roland 13 pin GK-series synthesizers with one guitar, either a 13 or 24 pin guitar.
The SBC-1324 is the unit I built to meet this need. The unit has both 13 and 24 pin inputs, and a master analog switch to select between the two. There are six amplifiers for each string input, used primarily to boost the 13 pin signals to the 24 pin format, but they can also be used individually to amplify any single string input, whether 13 or 24 pin.
Artist Highlight: Neal Schon
Journey guitarist Neal Schon was frequently seen in the early eighties playing a Roland G-505 guitar paired with the GR-300. Schon is not usually thought of as a 'Strat' player, much less a guitar synthesist, but he makes great use of the G-505/GR-300. An outstanding track is the tune 'Valley of the Kings', using the 'Duet' mode of the GR-300.

Gibson Custom Shop Les Paul "Studio Custom" Roland Ready Synthesizer Controller
Beyond the standard Roland offerings in the G-X0X series, there are vintage 24-pin Roland-Ready guitars for just about every niche: the Hard Rock Hamer A7, the traditional player's Zion Strat, or the cutting edge Steinberger GL-2T/GR.
But the classic, eternal, "Cadillac" of the series has got to be the Limited Edition 1985 Gibson Custom Shop Les Paul with the Roland LPK-1 Electronics. Every guitar was the product of Gibson's acclaimed Custom Shop in Kalamazoo, Michigan. Kalamazoo made Gibson Les Pauls have been called the 'Holy Grail' of electric guitars. These vintage guitars combine all the craft and musicality with the feature-rich Roland LPK-1 electronics package, the same electronics found in the G-303 or G-808 guitars.

Introduction to the Roland G-707:
Roland's commitment to guitar synthesis took a wild and unexpected turn in 1984 with the introduction of the GR-700 guitar synthesizer, and the G-707 guitar. In its previous incarnation, Roland had conservatively leaned on the knowledge and experience of Fujigen to produce guitars with familiar shapes and sounds: the Les Paul like G-303/808 and the familiar Fender designs of the G-202/505.
The G-707 was simply a guitar of the kind no one had ever seen, a strikingly original instrument in the generally derivative guitar market. Its 25 1/2" scale neck, and dual humbucker pickups, put it in the "super strat" category, but the wild body shape and stabilizer arm went places no major manufacturer had ventured before. I have yet to meet a person who has actually played the G-707 who did not remark on the ease and playability of the G-707 guitar. The ABS stabilizer bar really works to tame the inconsistencies of a guitar neck, if you can get past the visual effects. And much of the G-707 was never seen again: the Roland roller tremolo bridge, the newer, smaller electronics package that did not include the hex fuzz option of the G-202/303/505/808, and of course the ABS stabilizer bar.
The G-707 is really a performance instrument. The striking appearance will elicit remarks from a crowd whether its 1984 or 2017, but understandably it's nearly impossible to play sitting down without a guitar strap, something it has in common with the similarly forward-thinking Ibanez IMG2010.

Version History - The LEDs that never happened:
Unlike the previous Roland guitars, there is not much archaeological drama to the Roland G-707 guitar. The only differences I have detected are very minor changes to the guitar electronics package. The G-707 Service Manual Schematics makes note of LEDs, but provides no details. A closer look at the G-707 electronics card shows that there were provisions to include two power LEDS on the G-707 guitar, one for the positive 15 volt supply, and one for the negative 15 volt supply.
I have seen some cards with current-limiting resistors for the diodes in place, and some with them left off, while the silk-screening still shows the LED options. Consider this, if the G-707 was not striking enough, apparently Roland seriously thought about including glow-in-the-dark diodes on the guitar!
|Resistors R16 and R17 for LEDs on the Roland G-707.||A different G-707 PC board without resistors R16 or R17 installed.||Screened on the back of R16 and R17 is the legend for "LED"|
|Click on any image for larger view.|
Version History - Buffering the Volume Control Voltages:
The G-707 Service Manual Schematics also shows a buffering option the guitar and synth volume control voltages, but the buffering section, utilizing IC#5, is crossed out on the diagram. Like the diode variation, some cards do an operational amplifier in place, and some leave it off. IC#5 is a M5218, a popular inline dual operational amplifier. The M5218 is also used in the G-77, Ibanez IMG2010 and the Steinberger Roland-Ready guitars.
A little explanation: if the connected synthesizer "loads" the volume control voltage, the guitar synthesizer may have its volume reduced. So rather than reading a full 11 volts, the voltage may be reduced to 10 volts. Maximum volume on a vintage Roland synth is a control voltage of around 11 volts, expressed on pin 9, as synth volume, and on pin 10, as guitar volume. Pin 8 supports master volume, though this is mostly ignored by the vintage Roland synthesizers. The design of the Roland US-2 reduces the synth voltage slightly, meaning that synths played though a Roland US-2 are not as loud as they would be without the US-2.
By providing a buffer, it is less likely that the attached guitar synthesizer will reduce the synth volume output voltage. The G-707 was the first Roland guitar synth to incorporate a buffer circuit. The G-202/303/505/808 did not have a buffer circuit. Apparently Roland engineers had mixed feelings about the need to buffer the volume voltages, since as noted this feature is crossed off on the Service Manual Schematics schematic, though I have seen some G-707 cards with this feature in place.
G-707 Electronics Card with IC#5 Buffer Chip: S/N 2291385302.
G-707 Electronics Card without IC#5 Buffer Chip: S/N 2291385303.
A check of the Roland G-707 Service Manual Schematics shows that it only lists part number 2291385303. There is no mention of the earlier 2291385202 card which includes IC#5. Check out the photos of the STK-1 kit, based on the G-707 card. The STK-1 electronics card in the photos is the earlier version with both IC#5 buffer and the LED resistors.

A few years back I picked up a G-707 very much in need of a new paint job. Rather than go with silver, red, or black, I had the guitar repainted in brilliant white. As an added bonus, the original owner had replace the leg rest with a Steinberger folding leg rest, which worked great!

Modification: Roland G-707 Hex Fuzz Output Upgrade
Click here to learn how to modify the Roland G-707 guitar to add hexaphonic output
- Add Hex Fuzz Output for Roland GR-300
- Easy-to-find Parts
- Maybe used with BX-13 series if Hex Fuzz output enabled
Schematics - Repairs - Service Bulletins:
There are no known service bulletins from Roland addressing any G-707 problems.
The pickups in the G-707 really sound great, and unfortunately I have not been able to find much information about them, other than a very long Roland serial number. I did have a pickup from a parts project guitar, and pickup impedance read 7.55K.
