The Mojotone Mosfet switching board is a highly configurable switching system for your amp. With the included 2n7000 signal mosfets the source is grounded, the drain is run to a point in your circuit where grounding control is useful and the gate is run to a control line from the switching board (C1-C6). To switch an LED connect a mosfet source to ground, the gate to a control line (C1-C6) and then run a 130 ohm resistor from R1 to an LED and the LED to the drain of the mosfet. The GA5 mod schematic show an example of how this board can be used for a fairly sophisticated modification. See the GA5 mod schematic for an illustration of this.
