The new toy is a new-to-me used amp...a Roland cube, the 20XL-Bass. As far as I can tell, no longer in production.

My band practices in the drummer's basement area, and there's a fairly narrow stairway going to it. I got tired of dodging the walls with my Genz-Benz Shuttle on a 12T cab, or my Fender Rumble 100. It's more a size problem than a weight problem. ALso, the band practices at very moderate volume, so even the Rumble 100 was considerable overkill.

There aren't a lot of helpful reviews, but it looked to me like the Roland Bass cube would be an improvement that had enough power to work.

Here's a "gotcha" to be aware of: Roland made both a guitar and a bass version of this amp, with the SAME model number. If you look for one, make darn sure you get the "20XL-BASS" version, not the "20XL" version, which is the guitar amp. It's VERY common for them to be listed incorrectly.

Case in point: The first one I bought came from Guitar Center for under $200, but when it arrived it was the guitar version - the GC that took it in read the model number but didn't realize the missing suffix "Bass" was important.

So I returned that one and put the idea aside for a while, since the others I could find were all $50 to $100 more. But a week later I tripped over one on Reverb, and the price was the same! I ordered it because the photos told me it was the correct bass model.

Quick review:

Info taken from online specs at https://www.roland.com/us/products/cube-20xl_bass/

Lots of handy functions built into this COSM tech head, including a tuner, reverb, compression and a couple of other effects (delay, drive and a solo function). There's also a function which I suppose might be handy for practice in an apartment, the "Power Squeezer" which is supposed to provide "big, rich sound at low volumes." Not sure I'll ever need to use that. One little detail that counts: pushing the Tuner switch also mutes the amp while tuning.

There is three-band EQ, and separate gain and volume controls. There's a Headphone/Record Out jack if you want to use this as a source for the house PA, and an Aux in for a CD player or other music source input to practice with. There's a footswitch jack, but I can't imagine why it would be needed unless you were actually using this as a source for a FOH.

Weight: 20 pounds, 12 ounces. Dimensions are smaller than anything else I own at essentially 13 x 13 x 13 inches (give or take 1/2 inch.)

There are also six amp emulations: Super flat, Flip Top, Bassman, Bass360, Session, Concert 810. They are enabled by pressing a "Shape" button. To my ear there aren't huge variations in these, but there are enough that I quickly settled on using the Flip Top or Bassman settings, as they suit my ear playing decades-old flats on all my basses.

The sound from this 20-watt amp with 8" speaker is nice and bassy, and is quite capable of getting the 60's thump sound that I like. As long as I don't try to dime it, the speaker doesn't break up and gives good clean sound. I also found that running the gain up high results in some speaker breakup. I'm using the gain around 50% and volume for the rest.

I can get a sound quality very similar to that of the Fender Rumble 100 which works well in my band. There's enough volume there to work in any practice session that doesn't demand a great deal of volume. I could play a "coffee shop" gig with this amp, but of course I'd probably bring one of my more powerful amps on the principle that I can always turn it down.

Definitely a keeper, and it works well both for moderate volume practice and for getting up and down that tight stairway. I'd recommend this as one of the best practice amps I've found if you really are using it for practice or for very low volume gigs.

Great review. Never thought something that small would work in a practice setting with drums, but you've proven me wrong.

Thanks. In full disclosure, in practice the drummer usually uses brushes rather than sticks, and due to a bad ankle is currently not using a bass kick. However, he's not a loud drummer in any case so I believe it will still be OK when he adds a bass drum back in.

Great that you have a drummer who "gets it" with regard to volume.
ALso, the band practices at very moderate volume, so even the Rumble 100 was considerable overkill.
A few years ago, I was rehearsing in a basement area with a 150W 1x12" combo, and that was definitely overkill. I guess Roland/BOSS isn't kidding with that "HIGH POWER 20W" sticker on the Cube's grille!
 
Yeah like others I'm astonished that you can use this in rehearsal with an acoustic drum kit using only 20 watts into a 8" speaker. I see that your drummer is kick-less at the moment and uses brushes so I get how that helps. But still. I have never seen an 8" driver combo that made a proper bass sound at any volume, let alone play-with-others volume.

Roland watts are for real. I had a 12" combo - DB500 - and it was my moneymaker for YEARS. It was 160 watts, just like the new Bass Katana. I never had it past 3. Insane. It had very similar processing as this Cube. If I was in the market for another combo I would definitely go Katana. Roland/Boss are always quality in my book.
 
Happy NBD!

Your combo looks like a mini-me of the 120XL I have, which I bought after being very impressed hearing (& using) one at an open mic event.

I also have their little brother (the Micro Cube) which I got mainly for bedroom practice but have used it in jam sessions (for s&g) a few times for the Ric--o-sound treble channel. Even its 4x4" drivers (admittedly maxed out) were still clearly audible in that setting.

Like you, I really enjoy the tones I can get from the Roland. I wouldn't dismiss the footswitch however, as it looks like yours can be used, among other things, to activate the "Solo" channel function. If it's anything like the 120, this function allows you to pre-program the unit with completely different settings to what you then have dialled in, meaning you effectively have another channel and can change EQ, Drive, Shape etc etc. at the click of a (foot)switch.

Happy NBD again. I hope you get many years of enjoyment out of it. The two I have feel like they're built to last!

(Oh, and for what it's worth, I got death-stares from our drummer last time I suggested brushes for a particular song ... but he brought them out the next time we played it ;))

Nice score. Of all the gear I've bought and sold, the one I regret selling the most is my 2004(?) Cube 100. That was a fantastic little amp. I gigged with it for years and it always did the job with electric or upright. If I knew then what I know now, I'd have built a matching extension cab to get the full 200 watts and probably still be gigging with it here and there.

I have a cube30 Bass amp that I am very happy with. An older model to yours though, it doesn't have the "squeeze" button. It'snever been out of my practice room, so have no idea how it works in a larger setting. For that point my bigger amp has never been used out of my practice room either, because there was always a Trace Elliot at Church that was used until now, we have just gone to a silent stage.
