    I got to play through a Cube 15 this morning and was pleasantly surprised.

    The music school has a pretty motley collection of guitar amps. There’s a Fender Tonemaster that’s kept on stage, a JC 20 (not bad but a bit underpowered) a Fender B Jr. that needs some work (a bad buzz), an old Garnet tube amp that’s seen better days (donated for a tax receipt, I expect), and a Razors Edge/ZT Lunchbox (also donated for a tax receipt). A well-used Roland Cube 15 showed up today.

    We’re in a medium sized room: bass, drums, 2 keyboards, 2 guitars, and 4 or 5 horns. I thought the Cube held up pretty well and still sounded pretty good. I’ve got to say it took zero time to dial in a decent tone.

    The Cubes are good amps. The higher-end one are great amps. I've been gigging with a Roland Blues Cube Artist for several years now. Light, sounds great at ANY volume, loud enough for any gig- but still sounds great turned down as well.

    And I own some nice tube amps- Bad Cat, Swart, Supro...

    I've had a Cube 60 COSM for 15+ years, a reliable amp that I leave wherever whatever band I am in rehearses. Sounds good without a lot of tweaking, good stage amp, works great for jazz; I've never tried a blues or rock gig through it.

    Was it the orange one or the newer black?

    I’m guessing it would be from the early 2000s. Black. Not the 80s model.

    With old vintage Solid State amps, I always wonder about the condition of the Solid State electrical components.

    Solid State components electrical degrade over time.

    Just pondering, because some amps still seem to work fine.

    I bought an older Cube 60 that turned out to be a lemon. My repair guy has had it about 6 months and now he doesn’t respond to my texts.

    I’m wondering: surely a Katana 50 could reproduce the early Cube sound, at least the COSM era, without too much tweaking? Inexpensive, relatively light. I don’t see many being used in this context though.

    I had a COSM Cube 30 with a 1x10" for a while. The clean JC-120 sound with chorus and some reverb added where all I used but it was great for that. The overdrive and distortion sounds were horrendous as they had a weird plastic-y sizzle and latency to them.
