GuitarPCB Blues Power Quick Start Manual

Blues Power v1

Blues Power is unique in that it combines a simple MOSFET boost stage with a JFET "tube" stage. This is

based off the ROG Peppermill but with added clipping options to allow the circuit to exhibit more clipping than

the original and with LEDs a much warmer tube-style tone. We have also changed a value to allow more bass

response. Now besides being used a boost it can also work as an overdrive with Bass or Standard guitar. The

tone control is a low pass filter at minimum rotation, but at 65% rotation it changes to a fine high pass filter.

Board Dimensions (W x H) 1.63" x 1.26" ca. 41.3mm x 32 mm

D1 is a reverse polarity protection. D 6 i s an option to use the main board to hold the Bi-color status LED.

R10 – Current Limiting Resistor for on-board Bi-color LED. This may be adjusted to 4k7 for a dimmer light.
