I currently have an Ampeg SVT3pro and it has been a great amp for me. It is enough power. The only issue with the SVT3pro is the 8 or 4ohm output. I have a 4ohm Ampeg BXT210M and a 4ohm SVT410HLF. I bought these 2 cabs to use the 210 for smaller gigs/grab and go situations and the 410 for larger stuff. I would like to run both though at home. To do that right now I am using an Crown K1 power amp and running one cab per side. I found a used SVT4pro (online) for $700 plus shipping and wondering if it is worth changing from the SVT3pro. I like the built in crossover of the SVT4pro and would like the built in compressor, but I read it was not very good. Is it worth making the switch?
