Ampeg SVT-7Pro 1000-watt Tube Preamp Bass Head

The SVT-7PRO pumps out a ferocious kilowatt of pure Ampeg tone in a compact design that weighs in at just 15 pounds. The SVT-7PRO features the same professional features as the other PRO Series heads including a flexible 5-position mid tone control, remote switching FX loop and a sleek onboard variable compressor.

The tube preamp boasts a premium JJ 12AX7 that feeds the weight-defying Class-D power section. It’s portable and small but can power everything from a small single PN-115HLF up to a monster Heritage SVT-810E.
