Few heads cover as many styles as these. The flexible preamp lets you choose from pure tube to the fast attack of transistors, and everything in between. The switchable pre-shape gives and instant classic tone, and the well selected 5 bands in the Graphic EQ allow you to further shape your sound, to get anything from a classic Ampeg SVT to a modern EBS tone. The power amp pumps out a hefty 550W at 4Ω, so you’ll be covered in any situation. The switchable onboard subharmonic generator is probably the cleanest octaver we’ve ever heard.
