Roland GR-55 Normal-Guitar P7 & P5 (Safe) adapter cable

Музыка

The cable that turns a GR-55 into a high quality normal-guitar effects unit.
FEATURES:
* P7 normal-guitar input and P5 for PCM 'String A' PCM voice triggers.
* Allows external normal-guitar buffer use for exceptionally high GR-55 audio quality, with a straight analog-to-digital guitar signal path. GR-55 does not have a P7 input buffer circuit btw.
* Typical Boss pedal input buffer to GR-55 output specifications:
Noise-Floor -94.39dB. Harmonic Distortion: 0.00874% THD.
A custom gain-stage buffer pedal can register a -104dB noise-floor.
Hi-end project guitar buffer schematic:
separate-strings.co.uk/bufferschematic.png
* GR-55 normal-guitar re-amping via a DAW interface @ -27dB signal out. Hands-Free normal-guitar & P5 PCM voice patch changing. No more 'play a bit, adjust a bit' tone-search.
Finally, for those who might be thinking a GK3 normal-guitar input is ok to use, please consider GK3's poor unscreened normal-guitar buffer circuit, GK cable length and +7dB GR-55 power supply ripple, and bad audio!
Thanks for viewing,
Bill

    Outstanding Solution ! Now, with Just a Boss Tuner, I can plug in with a regular guitar chord and go without a GK-3 needed. Gig the unit as a Bass rig, Full Guitar rig with all the modeling AND have PCM tones if I want them. FANTASTIC Feature !

    Hi, You will have access to normal-guitar tones and effects, but only monophonic Pin 5 GR-55 synth voices (no poly). A Boss tuner will make an excellent guitar buffer. separate-strings.co.uk

    Hi, No problem leaving out P5. It was only added because a few people asked about it. Alternatively, you can switch off P5 or P7 in a patch. Regards, Bill separate-strings.co.uk

    Hi, If you want to make the cable, check out the v-guitar forums and search for 'phantom power' pin 8. You will find the basic P8 volume resistor network schematic (thanks to Steve Conrad btw). The circuit delivers approximately 5VDC to GR-55 P8 'volume level. Next is P7 normal guitar input, using a standard well-screened guitar cable. Conductor goes to P7 and cable screen to DIN shell. For a monophonic GR-55 synth voice, connect a 100 ohms resistor from P7 to P5. The resistor offers a basic buffer between P7 & P5. P5 'String A' has the widest GR-55 note recognition of all string signal inputs. The cable is available for purchase at £30.00GBP, plus shipping. The two hidden advantages with using the adapter cable input, is external user buffer pedal choice, and a clean input path to the GR-55's A-D. In tests, the GR-55 harmonic distortion is much lower compared to a Boss GP-10 or a GT1 pedal. And of course the signal-to-noise ratio (with a hi-end external buffer circuit) can register a -100dB noise-floor.

    Hi, GR-55 guitar emulations (strat, Les Paul etc) are not available with the cable, but guitar effects are available with a normal-guitar adapter cable input. The normal-guitar input audio improvement is noticeable, compared to a Boss GP-10 & GT1 multi-effects guitar input. A technical explanation is mentioned in an earlier post. The cable is available for purchase at £30.00GBP. Thanks Bill, www.separate-strings.co.uk

    I cannot ship to the Philippines, but you can make one for yourself. Go here christopher-j.net/roland-gk-13-pin-to-%C2%BC-inch-guitar-cable-adapter/ The person shows the basic connections for the adapter cable. P5 PCM triggers need a 100ohms resistor between P7 to P5. There is more on the Facebook GR55 page. Do have a look. Btw, Do not follow those videos with people connecting -7VDC to ground shield. They are totally stupid and dangerous. Thanks, Bill

    Hi I_ffoo, Do not see a problem with UK-Saudi Arabia shipping, need to check. Yes, you can play all the GR55 PCM sounds using a normal guitar input, BUT you can only input a single string guitar input or a mono input. The main attraction with the cable, is using a GR55 as a normal guitar effects unit. Btw, the GR55 has the cleanest of all Roland/Boss v-guitar normal-guitar inputs, and that's why I am so enthusiastic about the cable. Regards, Bill separate-strings.co.uk
