Roland Cube-30 COSM Modeling Guitar Combo Amplifier

The Roland Cube-30 remains one of the most respected practice and small-stage combos of its generation, built around Roland's COSM (Composite Object Sound Modeling) technology. Eight amp models cover the working guitarist's needs — JC Clean, Acoustic, Black Panel, Brit Combo, Tweed, Classic Stack, Metal, and R-Fier — with independent gain and volume staging on the Lead channel. Onboard EFX (Chorus, Flanger, Phaser, Tremolo) and a Delay/Reverb section round out the signal chain, with three-band EQ on top.

Housed in a road-ready cabinet with molded corner protectors, recessed strap handle, and a perforated steel grille over the 10" speaker. Aux In accepts a phone or player for jamming along; the Recording Out/Phones jack doubles for silent practice. A Foot SW jack allows channel and EFX switching. Tested and working; sound output is excellent across channels and effects.

CONDITION

Good and fully functional. Minor cosmetic scuffs to the cabinet vinyl and rear panel consistent with normal use. All controls operate; tested across clean and lead channels with effects engaged — sounds excellent.
