Picked this up from Jokerjkny early this year, and while I LOVE the tone of this head and how it communicates that signature thick aguilar tone with solid state quickness, I just like my Mesa Walkabout better, and don' t need much more firepower than that. The little Aggie is LOUD. I"m currently running it through a UL410, which is a great match up for clarity on the bandstand, but I should add that this head sounds stellar through 2 GS112's or a GS410. Aguilar seems to have tuned the mids on the AG500 to complement the slight scoop of the GS series, IMO at least. Head's in excellent condition, and I'm NOT looking for any trades. Need cash for a new axe. Price Lowered to $750 shipped to the Contl US!!!!! I greatly prefer a certified bank check, but am familiar with paypal if you'd prefer that method. Pics to come, and thanks for lookin!!!
