MXR

MXR’s first product was the Phase 90, released in 1972. Dunlop’s official MXR history traces the early line from that compact phaser to the Distortion+, Dyna Comp compressor and Blue Box octave fuzz—circuits that remain central reference points for the brand. JustPedals carries those classic families alongside the Carbon Copy analog delay, Micro Amp, Talk Box and bass effects. MXR’s range is deliberately broader than one effect category: compare the model number and version, especially where a classic circuit has later reissues, mini enclosures or expanded controls.

Compressor Pedals

Compression reduces the difference between louder and quieter parts of the signal. It can restrain peaks, lift decaying notes and make picking feel more even, but strong settings also change the attack and add audible sustain or pumping. Threshold, ratio, attack, release and blend determine when gain reduction begins, how firmly it acts and how much natural transient detail remains.

Bass

Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.

True Bypass

Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
