Warwick Quad VI Bass Head! Made in Germany. Tube amp tones with 600 watts of solid power. Amazingly capable, with a great range of tones.The Quad VI features a high-tech tube/solid state hybrid.
Unlike most hybrid amps that simply have a tube preamp, this head actually has a low-powered all tube amp – with three 12AX7 valves plus one EL84 -- combined with a high-powered solid state MOSFET power amp.The Quad VI controls offer just about anything you could want in tone shaping (see specs, below).
Try QUADRUMATRIX control position 4 for outrageously full tube bass!I include a picture of the internals, which shows the massive transformer which powers sound you can feel as well as hear (plus fan-cooled heat sinks to stop things getting overheated)
The full, weighty, punchy power this amp can deliver is a revelation for people who have only experienced the lightweight sound of recently fashionable bass heads. A change of life circumstances and impending house move mean I will have to part with much of my bass gear. I bought this amp
From Warwick:“From the days when bass amps had power, punch and a sound that hits you in the chest! This classic amp hand crafted in Germany became a favourite amongst bass players. Its hybrid combination of tube preamp delivers warmth and Mosfet power amp delivers punch & power.A powerful 600 watts of power gets the job done. The 12AX7 Preamp tubes provides warmth. The Amp also features an EL84 tube before the mosfet power amp to give full tube amp sounds.The Quad VI features Warwick’s 4-position QUADRUMATRIX control. Each position offers a unique preamp-shaped voice with the tone controls shifting to accommodate each. Positions 1 and 2 bypass the EL84 output tube, using only the 12AX7 preamp tubes. Positions 3 and 4 unleash the full potential of the output tube and transformer. Position 2 offers the flattest response, while positions 1 and 4 have more extreme shaping. Two frequency-shift buttons change the two mid controls’ center frequencies. Powerful LOW BOOST and HIGH BOOST buttons provide additional tone-shaping options. The QUADS simple-looking controls offer a lot of flexibility.”Note that Warwick variously describe the Quad VI as ‘600 watts/4ohms’ (in publicity and on the back of the amp) and ‘400 watts RMS into 4ohms’ (in the specs). Whichever, it goes seriously loud with great grip and dynamics.
Winner of the BASS PLAYER Magazine Editors Award.They Said:“The Warwick Quad VI is essentially a big tube amp minus the transportation and reliability issues. The QUADRUMATRIX preshapes, combined with the powerful tone controls, provide numerous texture and tone possibilities. European products are rarely a bargain in the U.S. due to additional export, shipping, and distribution costs, but the Quad VI is reasonably priced for an amp that offers so much.”
