This is a bit of a photo journal of the construction of my guitar amp. This was a very enjoyable process and I am pretty happy with the amp. Credit for the amplifier design goes to the fabulous site http://www.ax84.com/.

My amp is a minor variation on the P1 Extreme circuit from the chaps at ax84.

The cabinet design is my own, but some credit needed for the inspiration given by Uncle Doug
