I don’t own one, but I would have a good look at the Fender Bassbreaker 15. I’ve played them a few times in shops and am always impressed, they remind me a lot of my PRS Custom 50 tonally, which is a good thing. Full bodied cleans, good rock distortion and blues crunch. Also, the new Marshall Origin amps are very interesting, I haven’t played one, but can’t imagine them sounding bad with a PRS, or much else. I had an Egnater Tweaker for a while and got some good tones - I would say the imitation of famous amps fell a little short of authenticity, but coming at it from a standpoint of just using the options to get a good sound, it was a nice amp. Actually, I had the 15 head with a separate cab, different brand with a 1x12, greenback-ish speaker, and the 40 combo, I didn’t care for the speaker or the cabinet of the combo, it sounded boxy.
Of course, you can’t go wrong with a Mesa, as long as you’re aware of what a certain model sounds like and if it matches your desires, the discontinued models pop up used all the time.
If you want to get into a PRS amp, you’ll spend more, but they’re worth it. Great tones, superior build even on the import models, and much better stock tubes than other budget amps. I have a Custom 50, which has been my main amp for a few years now, it has a fantastic clean channel including for use as a pedal platform, the gain channel I can’t say reminds me of any other amp, it is its own thing, somewhere between modern and vintage. And, of course, the big new thing (or should I say small) is the MT15. If you like heavier tones, it’s an unbelievable amp, and quite affordable. You’ll need a cab, and a reverb pedal, but it’s worth it. I’ve found the clean channel to be extremely close to my Custom 50 (that’s high praise), and the gain channel is all the saturated, cascading goodness one could want. Or, if you want a combo, the Archon 25 or 50 are out there too, people are saying very similar to the MT15. I’ve not tried one but they’re a big hit.
