Im looking at a amp for my bass [ive recently took it up] and im looking at two amps

Both are roland cubes

First one is a roland cube 20xl and the other one is a roland cube 30.

Basically i want a quick answer on which one i should buy.Both are second hand and are pretty much the same price.I know they both have one or two features different from the other.

Its only for indoor bedroom playing.

Neither of those are bass amps, unless you mean the 20XL Bass. If you do, get that.

They are both bass amps.ive already got the Roland cube 40xl guitar amp.I would add links to them but im on my mobile just now.the 30 cube has t wah whislt the 20 xl doesnt but it has the power sqeezer.
