I have no experience with micro heads but am looking to get one, two that are available here are the Ashdown MIbass 550 and Aguilar Tone Hammer 500. I would value any opinions on either, the Ashdown seems to have more features in the EQ section, but I'm more interested in a good natural tone and reliability. I play finger style with five and sometimes four string basses. I'm in a standard rock cover band, two guitars drums and bass, also from time to time I do theater work, the cabs I would be playing through could be 1x12 for monitoring or 2x12, I also have two 15in cabs. I don't own a 4x10 but I would appreciate any cab suggestions that work well with either of the two heads. Many thanks Carl.
