Hogan offered me a vintage F2B at a great price so I jumped on it! So far I like the tone and while I miss a few of the modern features (mostly a tuner-out and DI) it's a nice item to have.
One issue though - it seems that when I drive it a little hard it builds up a sort of static charge or something, so that every so often a really loud "Blat!" comes out of the speaker. I turned my power amp down and the preamp up and it got a lot better - the "Blat!"s were less loud but didn't go away.
My signal path was Fender P-bass with EMG pickup and onboard EQ into a Nady line-mixer, to either channel of the F2B (I tried both, both had the issue) and then to my Crown XLS2500, into a 1x15" Eden cab. I used the "Mono" output of the preamp for my rack tuner.
