AMPEG SVP-PSB Bass Preamp Vocoder 70s circuit overdrives really wellAmpeg SVP PSB in full working order and very good condition. Bass preamp designed by Ampeg for bass legend Billy Sheehan. Spec from the manual: (see the full manual here) A unique piece of gear for the discriminating bassist, with two separate channels clean and overdrive and the ability to combine the two channels into a third, at the touch of a button.
