Description
Meet the Ampeg SVT 3 Pro, a true embodiment of the classic SVT tone with a modern twist. It is a lightweight bass head with an arsenal of tone-shaping tools, combining both tube and solid-state technology for a unique and versatile sound.
The SVT 3 Pro boasts three 12AX7 tubes in the preamp stage, added with another 12AX7 and a 12AU7 for a rich, full-bodied drive. These tubes provide the warm, classic sound that bassists crave, while the solid-state power section ensures reliable and consistent performance.
The amp's frequency control allows you to select the center frequency for the midrange control, offering five distinct voices for the midrange. The center frequencies range from 220Hz to 3kHz, giving you the flexibility to shape your sound to your liking.
Additionally, the 9-band graphic EQ allows further customization of your tone, making the SVT 3 Pro a real chameleon of bass tones. Whether you're playing smooth jazz, aggressive rock, or anything in between, this amp has got you covered.
