I have both the Carvin BX500 and the Ampeg PF500. The Carvin is a bit cheaper -- I found mine used for well under $300 and for that investment, at least so far, I have kept it as a spare and it is set up on the ready at all times in my music room into a 1x15 cab. Overkill for a practice amp, I know. I don't hear much effect from the tube on the BX and while the PF is solid state it emulates that Ampeg tube tone quite well so they kind of have their roles reversed. Neither is a one-trick pony as they each have compressor and good tone shaping capability, but their voices are inherently different. The PF seems more solidly built...like a tank. The BX is lighter and seems more fragile, though I don't mean to say it is flimsy at all. Output capabilities are similar, except the Carvin DI is only pre-eq, no post if you needed to send the house your shaped tone. I went with the whole Portaflex system with the PF 115 cab, so that was an advantage for me that is not relevant in your case. I must say I dig that PF and having one less thing -- even if it is a light class D head -- to load into a gig. It would be good to A/B them if you can to see which works best with your Fearful.
