My PF500 sounds good...real good. Is it all the tube goodness that my V-4B is? No. But, it definitely has the Ampeg sound without spending the coin to go all tube.
Edit: Having also come from the TH500, what I found was that I could get the TH500 close to the Ampeg tone (especially with a VT Bass pedal) but that I can absolutely nail the tone of the TH500 with the PF500 with the press of a switch and turning a few knobs. To me, the TH500 had something in the mids going on that I could never dial out. I wouldn't go so far as to say that the TH500 is mid-forward (though there have been some comments as to such and a thread floating around here about it) but I think what sets them apart, for me, is the ultra high and low switches on the Ampeg. The TH500 is absolutely relaxed in the highs where the Ampeg can get more "glassy" up top - especially with the ultra high engaged (I don't use this, just a little too much high for my tastes - no complaints with the amount of highs from TH500 either). I do use the ultra low switch though and, for me, this is where Ampeg can get a big, fat tone that the TH500 couldn't quite copy. Don't get me wrong, the TH500 sounds good but I think that overall the Ampeg can achieve an overall "fatter" sound that was what I was shooting for. Of course, just IMO and YMMV. Hope this helps.
Very interesting. I find the TH500 to be lacking a bit in the highs for my taste. I don't feel like it's missing much in the low, at least with my cabs and basses, but definitely a bit mid heavy to my ear, which isn't necessarily an issue for me. But you definitely have my attention. I am anxious to A/B the two brands.
B.S.
OP, if you want to try Ampeg on a budget, buy a PF-350. I bought mine new with full warranty over two years ago and have had ZERO issues with it. Cost < $250.00 at Musician't Friend.
This I would agree with. If you somehow find yourself short on power you can use the effects send/pre amp out and the "Ampeg sound" from the preamp is there for a second poweramp.
Great guys. Thanks. I might shoot for the PF350 or more likely the PF500 then and if I like it go from there.
