I'm looking for thoughts, recommendations, pros and cons of moving to a pre-amp / power amp rig rather than a head.
I have a small pedal board based around an Origin Effects BassRig SV to get "my sound" which is sent to both the front of house and back-line. I'm currently running a pair of Barefaced cabs powered by either an Ashdown ABM600 or a GB Streamliner 900 but I'm considering replacing the head(s) with a power amp and a graphic EQ (or similar).
The back-line rack would only need to deal with volume and the oddities of the room. The pedal board deals with tone shaping, compression, drive and all that. I'm giving FOH a "finished" sound for them to balance / tweak to the room and mix and want to do the same with my back line.
Someone in BC land has probably been down this (or a similar road) before but it would be totally new to me. Any thoughts on power-amps to check out (or avoid), similarly rack-mount EQs (or similar) as well as any big compromises / issues that people have bumped into?
