Hello. I'm a bass player from Australia and I recently sold one of my basses for $257 AUD and have my bass amp on $150 AUD at the moment. So after that particular bass and my only amp is gone, I'll need another one. My bass amp that I'm selling is a Fender Rumble 15, which leaves a lot to be desired. I'm only after a practice combo for my bedroom in my apartment. I was looking at the Roland Bass Cube amplifiers and I have played it in real life and it's pretty good, I like it, but it's the only one I can really try at the music store. Are there any other easily-accessible amplifiers that I should try out? If the Roland Cube is a good choice, how many watts would be a good choice for my situation? Thanks in advance. Oh also, I don't know if this is asked as much with bass amplifiers as it is with guitar amplifiers but the genres I like are mostly metal, grunge, most rock genres (from classic to modern).
