Watch the reviews of the Orange Micro Terror or the Orange Dark Terror. Both are great bedroom/studio amps for the price and depending on your budget and setup you can decide. Other and very different way could be a processor like the DIGITECH GSP1101 with a good cabinet emulation. I use this one with monitors in my small house and it has enough volume and quality to practice or record. With the right cab impulses you can sound as any amp you want. The smaller version, the RP155 is enough to begin, you only need a laptop and a good set of computer speakers.
