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

The cable that turns a GR-55 into a high quality normal-guitar effects unit. https://separate-strings.co.uk/gr55ad... 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!
