Brand
Roland is a Japanese electronic-instrument company founded in Osaka in 1972. Its guitar-related products include effects, amplification, pedalboards and guitar synthesis. The GR-55 combines guitar and bass synth sounds with amp and effects modelling, while the BCB series provides purpose-built pedalboard and carry solutions. JustPedals listings include GR-55S-BK and GR-55GK guitar synthesizers, an FV-50H volume pedal and BCB90X board components. Roland is a broad instrument maker rather than a single-effect stompbox brand, so check whether a listing is a synth system, pedal or rig accessory before comparing it.

A volume pedal places a foot-controlled attenuator in the audio path, varying level without changing the instrument itself. Potentiometer value and active or passive design determine impedance compatibility, sweep shape and high-frequency retention. Placement before gain changes both loudness and distortion response; placement later behaves more like a master level. Minimum-volume, tuner and stereo connections extend the basic function.

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.
Processes, creates or passes two audio channels. True stereo preserves separate left and right inputs, while mono-to-stereo effects generate spatial differences internally; routing, phase behaviour and whether trails remain stereo determine the resulting image. Some outputs sum to mono when only one socket is connected, which can change level or modulation depth.
