I have a Series 2 FDeck HPF. Considered to be an indispensable magic box for every gig bag. It did get me out of some jams in bad rooms, but I never really used it all that much. My AI head had a HPF built and I'm planning on buying a new Paradriver, which will multiple purposes, including this one.
I haven't used it or tried to use it in quite some time and it's been stored without a battery, so it's clean. Some obvious wear visible in the photo, but it's a piece of working musicians gear...so, $40 PayPaled to me gets it to you in the lower 48. If you want it elsewhere or faster, you chip in for the extra shipping and I'll get it on it's way to you.
