Up for sale is this used, very good condition Roland CUBE-01 guitar amp in dark grey with black reinforcement on the corners/edges.

The CUBE-01 was later rebranded as the current all-black CUBE-10GX to show where it fit into a larger line of CUBE amps. (10 = watts, G = guitar).

It's a 10W practice amp with a stereo 8 inch (20cm) speaker. The stereo speaker is for the AUX IN, not the guitar input, which is mono. The AUX-IN is not affected by any of the knobs on the amp; change the volume and EQ on the device that you have attached to the AUX-IN. This is good for adjusting your guitar/bass to match the AUX-IN volume just right for effective practice. 

Also features a headphone out jack on the back for headphones or recording. The headphone jack mutes the speaker if a headphone is plugged in, so that you can practice quietly.

It uses a COSM effects processor to provide a 3-band EQ, 3 amp modes, and a digital reverb effect.

Built like a tank, it's smaller, lighter, and louder than a Fender tweed 5F1 Champ.

In Acoustic mode, it can be used as a practice amp for bass guitar and still sounds good.

The speaker is in perfect condition (hard to see through the grille in the photos, but the perfect condition is obvious in person)

Includes the genuine Roland power supply.

Ships 10lbs USPS Ground Advantage or FedEx Ground/Home Delivery. It will be packed very safely.
