Three Iconic Blendable Amps in One

Meet the Clean Sink MKII

American, AC and Top Boost

Combining and layering multiple amp voices has often been one of the “tricks” the pros have used to achieve their signature sounds.  Based on the ‘clean’ channel of our flagship Kitchen Sink 6VEL amplifier, the CLEAN SINK MKII gives you the ability to do just that!

It features three blendable voices (American, AC or switchable AC Top Boost) that are managed by our proprietary Voice blend circuitry.  Pan hard left and you have an American black-panel voicing, hard right and you have British AC tones, anywhere in between and you’re creating your own signature blend of iconic guitar tones.

Running on a pair of 6V6 power tubes, the 20W CLEAN SINK MKII delivers a full-bodied tone and punchy response thanks to our enhanced enclosure featuring our legendary triangle ported back baffle design.  Our all-tube spring reverb, proprietary Hybrid-Master and Treble Damping control round out the features of this superb amplifier.

And like all of our hand-wired, point to point amplifiers, the CLEAN SINK MKII comes with a limited lifetime warranty for superb peace of mind.

Three Blendable Voices

American, AC and Top Boost AC!

How it Works

The CLEAN SINK MKII features a VOICING knob that lets you blend (layer together) American and British clean tones.  Pan hard left and you’re all American, hard right 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 AM with the AC for American Black-panel tones that stay clean and punchy while the British AC chime breaks up and sustains the same as playing through two separate amplifiers.  See below for a description of each of the three individual amp voices available on the CLEAN SINK MKII.

'65 Blackface

The CLEAN SINK MKII features a spanky clean ’65 Blackface amp voice with all of the fat blackface tone and bounce you’d expect from a vintage amplifier.

AC Normal

The CLEAN SINK MKII features a chimey clean AC tone and response that’s decidedly British with superb clarity.

AC Top Boost

At the flip of a switch, the CLEAN SINK MKII jumps to British chime with punched up gain and sustain – right in line with what you’d expect from a vintage Top Boost amp.

The Master Section

Where You Enhance and Refine to Perfection!

How it Works

The CLEAN SINK MKII features a mastering section to provide the tools you need to refine and enhance your tone.  HYBRID-MASTER™ controls your overall volume.  HF DAMP controls the overall high frequency content.  The REVERB controls the overall sense of space to your sound.  See below for a description of each control here in the mastering section of the amplifier.

Tube Driven Spring Reverb

The TUBE DRIVEN SPRING REVERB effect utilizes a dual-triode preamp tube operating in Class-A along with a real spring reverb tank to deliver an exceptional reverb effect based on 3P’s AMBIENT MODE.  The LEVEL control sets the overall volume of reverb.

HF Damp

HF DAMP allows you to control the high frequency content of your sound without killing the chime and harmonics.  Use this control when perfecting your sound in artificial listening environments such as in-ear monitors. Or, use it to sweeten up the high frequencies as part of your overall sound.


HYBRID-MASTER is our patented volume management circuitry that allows you to control the overall volume in the room independent of the tone and feel.

Enhanced Enclosure Design

featuring our legendary triangle ported back baffle

How it Works

The solid pine CLEAN SINK MKII 112 combo enclosure was designed to accommodate 12″ speakers of most sizes, including the Celestion Alnico Gold with its extended magnet bell design.  The new design also includes a baltic Birch back panel that features 3P’s unique triangle port design to deliver your full frequency response with a clarity and punch that sounds more like a mastered record and won’t get lost in the mix.  

This is the exact same tech principals we’ve utilized on our flagship amps and cabs including the American Dream, British Dream, Dual Citizen and helped contribute to the huge tones coaxed out of the original Dream Solo Series amplifiers.
