CapacitorsCapacitors are passive devices that are used in almost all electrical circuits for rectification, coupling and tuning. Also known as condensers, a capacitor is simply two electrical conductors separated by an insulating layer called a dielectric. The conductors are usually thin layers of aluminum foil, while the dielectric can be made up of many materials including paper, mylar, polypropylene, ceramic, mica, and even air. Electrolytic capacitors have a dielectric of aluminum oxide which is formed through the application of voltage after the capacitor is assembled. Characteristics of different capacitors are determined by not only the material used for the conductors and dielectric, but also by the thickness and physical spacing of the components.
Speakers & ComponentsSpeakers. The last opportunity to modify your tone. Unlike hi-fi speakers which attempt to create sounds that are true to the musical source fed them, guitar speakers impart their own tone. Your amp/cabinet pretty much determines three things about what speaker to select; speaker size, impedance and power rating. (See our tech corner article on Speaker Impedance, Power Handling and Wiring). But the tone is up to you! Speaker replacement is probably the easiest mod you can perform.

Capacitor - Peavey, 55V, 4700µF, Axial Lead
Peavey 4700 µF @ 55V polarized electrolytic capacitor with axial leads. 7/8" diameter x 2" length.
Bell Cover - Jensen Blackbird Speakers
Bell cover for 10" Blackbird and 12" Blackbird speakers. Jensen bell covers are a throwback to the style of classic Jensen speakers from the 1950s and '60s that can complete the look of a vintage or vintage-inspired amplifier.
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.
