Hi- I have an amazing Ampeg PF500 head, however, since i got some other Ampegs, but non of the Aguilar heads, id like to add that flavor as well. So ill trade my PF500 towards a TH500. I am not familiar with the Tone Hammer, but the PF is out of this world and brings total Ampeg sound with very impressive flexibility (from super scooped modern, through B15 mid thump to Punk Grind). ill take my chances, let me know if interested in some configuration of a trade. Thanks!
