I've been reasearching this head and and have read more than enough about it to know that it distorts at a decent volume. I was wondering if there is a remedy for this. I was wondering if the solution to more power for the Bass 400 could be applied here. Could you replace the tubes in the Buster Bass 200 with 6550s and add more power like in the Bass 400? What about the KT66 tubes? Would the transformer(s) be capable of producing more power with tubes other than the 6L6?
