Reposting this since I'd now sell it for $425 shipped, or trade for (or towards) a higher-powered head.
Edit: For sale now for $400.
I love this head, but my band is pretty loud and my cabinet of choice is 8 ohms...I'm able to get by with the F1 but I'd like to have a little more in reserve.

As you can see, it has its share of bumps and scratches, but it works just as it should.
Thanks,
