ABCY – a pedal that enables you to switch between three guitar amplifiers. The A, B, and C represent the three amps while the Y signals all three amps to be turned on at the same time.
Amplifier (amp) – a device that increases the strength of the electrical signal coming from the guitar or bass pickups and is set up as either a combo amp or stack.
Amp head – contains the amplifier that passes the signal via a speaker cable to a cabinet to produce sound. It is attached to a loudspeaker cabinet to form a stack.
Archtop – a steel-stringed acoustic or semi-acoustic guitar with a full body and a distinctive arched top that creates a strong bass tone popular with jazz musicians The archtop guitar was designed by Orville Gibson in the 1890s to modernize the guitar by enhancing the power and quality of its tones.

Pickguard – a piece of plastic or other laminate material on the body of a guitar that protects the finish from being scratched by the guitar pick.
Pickup – electromagnets that are located on the front of the body. They produce a magnetic field that is disturbed by vibrations in the air (caused by the strings) which in turn alters the signal that is sent through a cable to the amp. The amp then receives the signal and amplifies it. There are two types of pickups: single coil and double coil.
