I couldn’t disagree more with amps designed like this. Every amp I drop the bias on immediately becomes much tighter , aggressive, bigger low end and bigger highs.. I have clips of my Diezel Einstein I did this with just to show the fact and kept everything else exactly the same in the signal chain, you can’t dispute it, Atleast with that amp in that scenario. My Herbert was exactly the same experience, and the super hot 5150s always sound like a flubby smooth bloated mess when turned up a bit compared to the “cold” stock 5150s.
Of course, this is all amp dependent and relative to the design of the power amp in what is considered “hot” or “cold”, for sure. The fortins I know for a fact though, Atleast stock, are ridiculously hot.
as far as needing a bass player, I’ll admit my experience is more specifically aimed at recording vs live, I have no opinion on fortins live to be honest. But for tracking, where you can get away with much more than you can live ( in regards to amount of bottom end or high end or lack of/excessive midrange for example) the fortin stuff was some of the absolute worst amps I’ve ever heard under a microphone. Olas videos of where he has 6 or 7 amps in the room shows this perfectly what I am talking about. I mean it’s awful. All mids, no highs, no low end, every other amp stomps it, and this was my experience in the room as well, let alone tracking one.
