A guitar speaker isolation cabinet is a sound-proof enclosure that surrounds the speaker and sound-capturing microphone and prevents sound leakage into the outside environment, enabling the guitar amplifier to be turned up without excessive listening volume. An amplifier and speaker at full volume can be extremely loud, posing a risk to hearing and an annoyance to neighbors, and will often drown out other instruments in a mix in live shows. In a recording studio, the sound of an amplifier at full volume may spill into the microphones for other instrumentalists. The characteristic sound of a tube guitar amplifier as heard on the majority of professional recordings is achieved by playing the amplifier at high volumes and using one or more microphones to capture the sound. Turning the volume up causes the pre-amplifier to overdrive and it drives the power amplifier into distortion and the loudspeaker to "break up", adding intentional distortion to the amplified tone. Sizes and types A guitar speaker isolation cabinet has a built-in mounting baffle for a guitar speaker and a permanently mounted microphone clip. A compact isolation cabinet contains a small guitar speaker such as 6½" diameter and sometimes an attached power attenuator to prevent blowing the speaker. A guitar speaker isolation box is large enough to contain a standard guitar speaker cabinet such as a 1x12", 2x12" or 4x12" cabinet and a couple of compact microphone stands. Inexpensive but less effective DIY implementations of this approach are to put a guitar speaker and microphone in a closet, place gobo partitions around a speaker cabinet to somewhat deflect the sound, or form a tent with multiple layers of heavy blankets over a guitar speaker cabinet and microphone. An isolation booth is a small room large enough to contain a single performer along with a rig, enabling the instrument to interact with the amplifier while isolating the rest of the band from the extreme volume. Finally, the live room of a recording studio provides sound isolation between an entire band and the control room, allowing the studio engineers to work at manageable volumes and prevent listener fatigue. The frequency response of an isolation system depends on the number of microphones, the type of microphones, microphone positioning, cabinet dimensions, speaker size, speaker model, and the amount of sound-absorption material inside the isolation cabinet. To control the resulting response, a dedicated equalizer can be used to enhance or reduce
