I’ve been using ABM gear for years now, and no complaints at all from me. Plus side is that they can sound great (especially for any kind of rock-based stuff), well made, have a very powerful eq, and good connectivity. Downside is the combos are a little bit hefty (which is why I have separates!). Obviously there’s a lot of alternatives around – and if you search this site you’ll see some quite polarised opinions, which often boils down to whether people like the inherent tone or not. These amps do have a certain signature sound. In terms of speakers - I’d say the ABM 210s sound more defined and tighter than the 115s. And with the 300w version, depending on your band, you might need an extra cab to go with a 300 combo (ie another 210) at some point.
