Tonnes of Tone, Electronics Projects for Guitar and Bass
by Kevin O'ConnorA collection of projects for electric guitar and bass players. Save money by building your own acoustic preamp; build a two-channel tube preamp for guitar, and more. Construct a 15W tube power amp or a true class-A solid state amp. The "experimenters power supply" is excellent for tinkering with tube circuits, containing separate AC heater, DC heater plate and bias supplies. Build a wide range of tremolo circuit and an all-tube reverb unit. Circuit operation, construction, & layout guidelines are provided. Every project uses easy to find parts.
Capacitor - MusiCap, 100V, Film & Foil Polypropylene
Critical loudspeaker crossovers deserve to have a transparent product specific to the application. Speaker MusiCaps, with their thicker leads, are a revelation in well-designed crossover networks. While a fully MusiCap-ed crossover is supreme, just installing MusiCaps in the tweeter circuit will reveal much additional detail and nuance. Many prominent high-end loudspeaker manufacturers have been using MusiCaps in their top models for years.

Neodymium magnets offer a 50% reduction in weight guaranteeing very light systems. The proprietary aluminium basket was specially designed to avoid sound wave reflections on the rear side of the cone, thereby allowing for faster and better cooling of both the voice coil and the air moved by it. The 12'' bass speaker provides a good upper mid range tone.
