Since almost immediately after its introduction in the 1990s, the Avalon VT-737sp vacuum tube channel strip has become the platinum standard for highlighting a lead vocal or giving a "finished" sound to a bass or keyboard track. The likes of Dr. Dre, Kelly Clarkson, The Crystal Method, and countless other A-List artists and producers rely on the VT-737sp's crystalline fidelity, vast tone-shaping ability, and military-grade build quality to keep the hits coming.
