Dating a peavey amp
High-end tube instrument amplifiers have survived as one of few exceptions, because of the sound quality.Typically, one or more dual Rear view of a tube (valve) combo guitar amplifier.In addition to a 1/4" input jack, acoustic guitar amplifiers typically have an additional input jack for a is not often provided on general-use amps, restricting the choice of microphones for use with these inputs.However, for high-end acoustic amplifiers, phantom power is often provided, so that musicians can use condenser microphones.Semiconductors are very heat-sensitive by comparison and this fact usually leads to compromises in solid-state amplifier designs. While solid-state devices are also replaceable, it is usually a much more involved process (i.e.having the amplifier tested by a professional, removing the faulty component, and replacing it).Amplifiers with processors and software can emulate the basic tone of a classic amp anywhere from poorly to well, but the full response of these amplifiers may not feel the same to a player as the digital modeling does not accurately reproduce all aspects of a tube amplifier.applications until the 1970s, when semiconductors (transistors) started taking over for performance and economic reasons, including heat and weight reduction, and improved reliability.
Amp heads may also have the different types of input and output jacks listed above in the combo section.
Some modern amplifiers use a mixture of tube and solid-state technologies.
