8. Once the voltages are all within spec, carefully plug your guitar (or harp mic) into the input jack,

taking care not to touch the exposed circuit board. Make some noise.

Turn up the volume. It

should sound great!

TIP:

If it turns out that

you need to re-solder any of the

resistors, don’t bother removing the

board from the chassis to get to the
solder side, just solder them on the

component side of the board.
