Cable Tester - Here is a device that musicians will find highly useful.
It will detect breaks or shorts in a guitar or monitor cable. Much more
elaborate cable testers are available at music stores, but they are fairly complex and
are mostly useful to road crews and technicians. The musician doesn't really
care what is wrong with cable, only whether it's good or not. You can't beat
this tester for simplicity and ease of use. It is also extremely compact and can
be easily stored in a gig bag...[Designed by Andrew R. Morris] |

Guitar Fuzz Box - Fuzz is one of the classic guitar effects, and this simple
circuit generates it quite well. The circuit is so compact that it can be built into
guitars or amps that do not have built in fuzz to add that capability to the
instrument. The circuit does not use much battery power, so a standard alkaline
battery will last many years even with daily use. [Circuit designed by Aaron
Cake] |

Guitar Reverb Circuit - This is a circuit for a guitar spring reverb pedal,
it has dry, wet, and drive controls for a wide variety of sounds. With a decent reverb
spring (tank) in overdrive, this circuit will produce an incredibly thick and grungy
sound, build one and be the envy of all of your guitar playing friends. This
thing is fun to play through [G. Forrest Cook] |

Guitar Reverb Effect Version 2 - This is my second-generation guitar reverb
circuit. The fidelity is much improved over the earlier design, it is suitable for use
as a front-end to a guitar amplifier. This circuit features clipping indicators
on the preamp and reverb recovery stages, allowing for the optimal gain settings....
