Ruby Amp in a Magic 8-ball

Ruby Practice guitar amp housed in a magic 8 ball

The Ruby Amp is a great little battery powered solidstate practice amp. The design is based on the Little Gem design which in turn comes from the Smokey Amp designed by Dave Stork on www.blueguitar.org. The design uses relatively few components and is a good DIY project. Cigar box guitar maker J.K. built a Ruby Amp but found himself hunting for a suitable enclosure for it. Then he noticed an old magic 8 ball that looked just right with a perfect sized hole for the speaker.

Is this a good amp? ...<Shakes ball vigourously>... Signs point to yes!

The distribution of Goya guitars then went to Kustom Electronics Inc. and then to Dude Inc. sometime in the early 1970s. Levin-Era Goya models have an interior paper label with the Goya trademark in a script style, reading "Made by A.B. Herman Carlson Levin - Gothenburg, Sweden".

The Martin Guitar Company took over the Levin company by 1975. By the late 1970s Martin Guitars started making the Goya guitars in Japan then moved manufacturing to Korea during the 1980s and finally to Taiwan during the 1990s. Martin stopped making the Goya brand guitars in 1996, although it still owns the brandname.

Make a wooden practice amp

woodenamp.jpg

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.

These were designed and made by Sam Koontz and The Harptone Manufacturing Company.
