looking on the used market (cause I'm a broke fella) for a small low wattage tube amp. Can be a combo or just a head. The usual options; Vox AC4, Blackheart Little Giant, Epiphone Valve Jr. Am I missing some others? I'm looking to spend no more than $150 (used). I don't like easy break up. Looking for something sparkly, or that will work well and not be muddy, with humbuckers (using a Les Paul). Thoughts/suggestions?
