Sound samples of a Ampeg SVP Pro tube rack preamp.
Testing this 5-tube classic sounding rack preamp. It can go from very clean to very dirty. Huge EQ options with all the switches and 5 different mid frequencies. In my SVP I put those tubes: Tung-Sol 12AX7 in V1, JJ 12AX7 in V2 & V3, stock chinese 12AU7 in V4, Groove Tubes in V5. Recorded on a Warwick Corvette $$ 5 bass - passive mode, blend 50/50, pickups in single mode.
