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.

Fuzz Pedals

Fuzz drives the signal into extreme clipping, often flattening the waveform and generating a thick spectrum of harmonics. Transistor type, bias, input loading and tone filtering create markedly different responses, from loose and velvety to gated, spluttering or octave-rich. Some circuits interact strongly with pickup impedance and guitar volume, while others include buffers or blends for a more consistent response.

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.
