I've heard a little talk here about guitar power amps vs. bass and pa power amps. Some say that the transformers are wound differently, and you shouldn't use a guitar power amp for bass. Is this similar to how pickups are wound for bass and guitar? What would be the dissadvantage of using a guitar power amp vs. bass or pa, if any? I've got a Boogie Coliseum 300, which sounds great, but I'm wondering if I am missing out on anything? If I am I may scoop up a Strategy 400 instead. Comments?
