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.

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.

* 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,
