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.

Preamp & DI Pedals

A preamp brings an instrument signal to a controlled level and shapes its impedance, gain and frequency balance before amplification or recording. A DI converts the signal for a balanced, low-impedance connection and may include ground lift, pad and transformer isolation. Combined units can add drive, cabinet filtering, effects loops and parallel outputs while keeping the direct path stable.

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.

Vocal

Designed for microphone-level signals and the frequency, dynamics and feedback behaviour of the human voice. Input gain, balanced connections, phantom power and pitch tracking may be provided so effects respond correctly before the signal reaches a mixer or PA.
