I'm looking at a couple of options for a low power plexi-toned amp. I have a Rockytop 18 112 and like it, but it is a little loose and lacking definition on the bass end. I'm not sure if it's the open back cab or just the nature of the amp. I'd also like a little more clean headroom. I've thought about a Ceriatone 36 watt or mabe a 2061 clone. Anyone have any reports on either the Ceriatone versions of these or others? The downside of the 2061 circuit seems to be lack of eq on the amp (the 36 watter has a tmb channel) and maybe lack of headroom, although Ive not played one to know (no one around here has either amp to demo). Also, has anyone power scaled either of these? Are they better/worse suited for PS than other amps? Thanks.
