I know Dave Gilmour uses the F-2b and has been for years. The gilmour web-site said they changed capacitor values to make it less bassy and added a preamp tube...any suggestions. |

Was the F-2b in his regular rig? I remember reading it was used for the Leslie signal path. |

Thanks Dave, ...and Welcome Eric...good question, I wonder if the extra tube stage was added in the front, if so you might be able to simulate what Gilmour was getting by putting something like a BK tube driver before the F-2B. |

I use an F-2B through a Mesa 50/50, along with a Demeter Real Tube Reverb and a SF-2 in my guitar rack rig. The F-2B works fine as a guitar preamp. In fact, IIRC, the F-2B is based on the Fender Dual Showman, a guitar amp. Bill, tgo |

just googled gilmour alembic mods and got my answer. The tube was added as a cathode follower to lower impedence |

Cool, I see that mentioned in the thread here I see how a lower impedance would be good for Gilmour's rig considering how many pedals/processors might follow the F-2B. Half way down this page it mentions: "To optimize the unit for guitar, it was modified by adding an extra tube in the preamp section for a little more drive, lowering the impedance in the output and changing the capacitor in the bottom end to eliminate some of the lows to prevent “boominess” in closed-back cabinets." |

Mine is set up so you can easily cascade the first tube stage into the next, but it does not do anything exciting for me that way. |
