Hi,
I've seen a lot of topics about power amps, but not so many about what makes them any different from the power amp side of a regular amplifier...
To make this thread a little different, I want to talk bang-for-buck a bit with my situation and answer the question of why not just always use a bass head for a power amp?
I want to have the option of outputting line-level or hooking up to a cab in both of my bands, one where I play guitar, the other I play bass. It's not economical for me to buy two amps and cabs when I've already got a helix, but for an alarming amount of local venues, I need that cab-compatibility. So I started thinking about a dedicated power amp when I realized that FX loops are basically just a shortcut to the power amp built in to the amp. Is there a even a difference between the two things?
My assumptions are:
A 150w bass amp will cost a fraction of what a 150w power amp costs, same generally with higher wattages until you get to fancier models.
Any amp with an FX send has intrinsic value greater than a power amp because it is both a fully capable power amp and a fully featured amp
If you're not using the preamp section, bass or guitar, it doesn't matter...
A bass amp will generally have higher wattage than a guitar amp, so bass amps have greater compatibility across cabs than a guitar amp, just maybe it's a little louder...
So what's the magic sauce in a power amp that would make me spend $400-1200 when I could get more value for the same or less on a bass head?
