Thank you very much, what about biasing? the DIVO does it automatically but how much or how often is it to get it done in a shop? If i like the rockerverb, should i get the rockerverb 50 with a 212 instead of a 412 then? i love the tone and versatility it offers. I do like the TH30 but it doesn't offer me much variety it seems.
Your tubes will need biasing every time you need new tubes. Probably not often if your playing at low volumes, maybe a couple years. You can expect to pay anywhere between $100-$200 including tubes. If you want a 412 go for it. 212 are really good too. Just personal preference there regarding sound and physical size preference. But I agree that a Rockerverb 100 and DIVO would be overkill for you.
