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.

Utility Pedals

Utility pedals solve signal-path tasks rather than imposing one recognisable effect. Buffers restore level and high-frequency response lost through cable capacitance, selectors route between instruments or amplifiers, summing boxes combine paths, and isolators interrupt hum-producing ground loops. Impedance, phase, transformer isolation, active or passive circuitry and switching method determine whether the routing remains quiet and transparent.
