Description
The SVT-3 PRO is where Ampeg’s tube preamp character meets a rugged solid-state power amp, giving you that unmistakable growl without hauling around a full tube power section. Three 12AX7 tubes shape your tone up front, while the MOSFET amp pushes 275 watts at 8 ohms or 450 watts at 4 ohms — plenty to anchor a room without babysitting your gear.
Dial in your low end with the 3-band EQ and 5-position mid frequency selector, then fine-tune further with the 9-band graphic EQ and ultra low/high boost switches. Whether you’re going for scooped funk or a growling rock tone, this head gets you there fast and keeps it consistent set after set.
Built for real gigging bassists: the Mute button lets you swap basses mid-set with zero pop, and the Tuner Out stays live even while muted — so you’re never caught tuning in silence or interrupting the flow. Neutrik Speak-On connectors lock in tight for a reliable connection, and the variable-speed fan only kicks in when needed, keeping things quiet and cool on stage. DC-supplied filaments keep the tube stage dead quiet.
