The Ultimate All-in-one Tube Amp Solution


If you can hear it in your head, you’ll find it right here in the Kitchen Sink. The elegantly designed control panel puts essential American and British guitar amp tones instantly at your fingertips. And the new 6VEL model cranks up the sonic immersion in every way, with a wide variety of tube options, layered (blend-able) American and British clean voices, JTM, JMP and “Jose” era Plexi voices, switchable rectifier modes, Hybrid-Master™, as well as a powerful channel/scene-change foot control switching system all built in.

The Clean channel features a GIANT KNOB that lets you blend (layer together) American and British clean tones. Pan hard right and you’re all American, hard left and you’re all British. Pan in the middle and you’re playing through both amp voices simultaneously. Each voice stays clean or breaks up as it should based on where the volume knob is set. A great example of this would be to blend the ’65 Blackface with the AC Top Boost for American tones that stay clean and punchy while the British chime breaks up and sustains the same as playing through two separate amplifiers. See below for a description of each of the four individual amp voices available in the clean channel.

The Dirty channel features a tone stack voicing switch that delivers the sweeter JTM tone control voicing and balanced gain response in one position, and the more in your face JMP voicing in the other. The Gain control knob cascades through multiple tube gain stages in a unique way that starts out with Classic Plexi tones early on the dial giving way to scorching High Gain tones later on. The Gain Boost switch engages even more gain as well as kicking in our unique clipping diode circuit that gives you the sustain and precision of a ‘Jose’ but retains the organic Plexi clarity when backing off of the guitar’s volume control. See below for a description of each of the three individual amp voices available in the dirty channel.
