level of difficulty:
This is a photo gallery of a project to build a practice amp out of a solid block of quilted maple. Every part of it is hand crafted, he even makes the control knobs on a lathe.
The end result looks great, you can see that this guy has a talent for 3D design - there are curves everywhere. The amp turns on when you plug the lead in. The green light gets brighter as you play, depending on the volume of the input from the guitar. It also pulses if two strings are out of tune to help you tune your guitar.
