Ashdown Retroglide 800w Head Complete Tonal Control with power to spare A comprehensive 12-band graphic EQ covering 30 Hz up to 15 KHz allows you to easily shape your perfect bass tone in seconds and the 800 watt power section means you have headroom to spare whatever the gig. Ready to go anywhere in the world Plug into the power anywhere in the world and the Retroglide will auto-sense the mains supply from 100-240v. No messing around with slide switches and forgetting to flip it back when you get home. Job done! Total Connectivity Hi & Low Impedance inputs allow for active and passive basses whilst an Effects Loop allows you to plug your favourite pedals directly into the power section so as not to degrade your overall tone. The sound engineer will love the post EQ balanced DI out plus a line in allows connection of auxiliary devices for backing tracks. Finally a professional standard Neutrik Speakon/Jack combi out allows connection to a variety of cabinets. Looks as good as it sounds The exterior is beautifully finished with a hand machined and polished alloy front panel engineered to protect the sliders from being damaged in transport. The mild steel lid also overhangs to protect the input and output controls.
