Ampeg SVT-4PRO Rackmount Bass Guitar Amplifier Head, Hybrid Tube & Solid State, USA-Made


+ shipping

Up for sale, an Ampeg SVT-4PRO rackmount bass amplifier head in excellent condition and in perfect working order. Not to be confused with more recent examples of this head produced elsewhere, this Ampeg SVT-4PRO is a genuine USA-made amplifier from the era when Ampeg was owned by St. Louis Music (SLM Electronics). This amp has also been given a recent checkup and clean bill of health from our techs here at Mike & Mike's Guitar Bar.

The SVT-4PRO is designed for the player who wants SVT tone and performance (with a few modern enhancements) in a convenient, high-powered, rackmount design. The bass amp head offers an expansive palette of tonal options with a tube-driven preamp boasting three 12AX7 valves, paired with a solid state power amp. The Frequency control allows the player to select the center frequency for the Midrange control, providing five distinct voicing options for the Midrange. The additional 9-Band Graphic EQ is available to further fine-tune the signal, and conversely, it can be set up as a footswitchable “second channel” with a volume boost.

The head is in great shape, with all knobs intact and clean graphics on the front and back of the chassis. There is light wear on the rack ears and a few scuffs on the enclosure on the whole, largely on the bottom.
