- Bare board (requires SMT soldering skills, components and box not supplied)
- SMT board (requires basic soldering, GK sockets, box and jacks not supplied)
- Assembled board (Fully soldered, box supplied, you drill the box)
The P7 breakout is kept as stock in either the Bare board or SMT board configuration. If you’d like an Assembled version, place a back order and it will be built to your desired kit level.
GR55 (or 13pin device) Break in box:
You can use the P7 to break into the GR55 with a normal guitar by plugging a guitar lead into the jack input and a GK cable into the to GK output. This gives you access to the GR55 modelling tones with normal guitars. It’s also useful to allow you to carry a non-GK guitar as a backup for a GK instrument.
GR55 (or 13pin device) as a multiFX pedal:
Plug an FX send into the P7 jack input and an FX return into the GR55 mono output and you can use GR55 FX with a normal amp setup. Adjust volume to taste, but try starting with Patch Level between 100-130 and the volume knob at about 11 o’clock.
GK cable Break out box:
The GR55 guitar out socket is too noisy for use with high gain setups. Many users run the magnetic signal down a guitar jack cable and the GK signal down a GK lead to avoid this. With the P7, you can plug a GK cable into the GKinput, and a normal guitar cable into the P7 output, accessing the magnetic tone and bypassing the pedal. No batteries are necessary, because the P7 is powered by the GR55.
Select between magnetic signal on a 13 pin guitar and a normal guitar
You can use the P7 with jacks in the input and output alongside a passive AB or ABY switcher box to select between the mag-only straight from the guitar and the break-out jack of the P7.
