Output board 13pin with 7 preamps

this is the best solution if you want as little as possible in the guitar

• 7 channel low noise preamp,
• each channel with gain trimmer
• Roland GK 13pin output
• needs no battery since it works with the supply coming from the 13pin
• can be mounted to a front pannel or a acoustic guitar side with 2 M3 screws
• the 7th channel is meant for either a magnetic pickup or a body piezo or an internal microphone
• a potentiometer for VolGK and buttons for Up/Dn (S1/S2) can be connected to a 6pin header
• the pickups can be soldered (like RMC) or connected to a 2mm pitch header (like Graphtec GHOST)
