Last month I bought a Roland Microcube bass amp to practice with while I was staying at my parents' house over the holidays. While it is a sweet little amp, it is only 5 watts through four 5-inch speakers. I don't need a practice amp to be high-powered by any means, but I was afraid of turning this thing up, especially with my active basses. That being said, the tempo / rhythm feature was handy and I especially liked the "tap tempo" option. Nonetheless, I think I am going to return it to Musician's Friend. I still have about 10-12 days left in my 45-day return period and it's still in mint condition. I paid about $240 for it and would rather use that money for something else. I was thinking about picking up a used Fender B-DEC 30 (now discontinued) as a practice amp. It is 30 watts through a 10 inch speaker, so while I certainly won't be gigging with it, I feel like it may offer a better sound in my practice room or living room. Plus it has backing tracks and other cool features. I have some questions though, for those of you who own one (I've looked all over the internet and could not find the answers I'm looking for.) Do you HAVE to play with the backing tracks or can you play with just a raw drumbeat? There are some situations where I may not want the keyboard/guitar/whatever else going and would prefer just hear the drummer. Is there a tempo TAP feature? If not, how do you set the tempo? I have seen these online for under $200, so I may be able to return the Microcube, buy a BDEC-30, and still have a few bucks leftover. Ultimately I just need a good practice tool where I have full control over the rhythm. A drum machine is another option but the idea of a small amp is nice because then I can take it on road trips and that sort of thing. Thanks!!
