From 3rd Power:


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 KS 6VEL gives you the choice of a solid-state rectifier for more maximum headroom and punch, or a tube rectifier for a sweeter, warmer response. Use a 5U4 for supreme tube compression or go with a 5AR4/GZ34 for a response that’s more in the middle.


The KS 6VEL runs on a pair of E34L power tubes (for 40+ watts of power) or run 6V6 tubes (for 20 watts of power). Want some variety? Go ahead and run 5881s or 6L6s. Bias adjustment and meter patch points are located on the back panel.


The KS 6VEL features JJ ECC83S short-plate tubes operating in Class-A for both the American and British preamp circuits, tone stacks and the FX loop. The Reverb and Phase Inverter each operate on a Sovtek 12AX7 LPS long-plate tube for maximum signal gain and lower noise.


Controls Four Different Amp Tones!


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 KS 6VEL features a spanky clean ’65 Blackface amp voice with all of the fat blackface tone and bounce you’d expect from museum grade example.


At the flip of a switch, the KS 6VEL becomes a ’62 Brownface amp with a midrange growl that’s somewhere between the Tweed and Blackface.


From the other side of the Atlantic, the KS 6VEL delivers a chimey clean AC tone and response that’s decidedly British with superb clarity.


At the flip of a switch, the KS 6VEL jumps to British chime with punched up gain and sustain – right in line with what you’d expect from a vintage Top Boost amp.


JTM, JMP, and Jose-style Plexi Voices


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.

’65 JTM

The JTM45 debuted in ’65 bringing the punch and sustain of a certain American style bass amp but with a decidedly British angst. One circuit common to both was the tone stack featuring a 56k ohm slope resistor and a 250pf treble capacitor. This made for a sweeter tone with emphasis on the melody strings.

’68 JMP

The JMP amplifiers debuted around late ’67 bringing with it a distinctive mid-range frequency slice, increased sustain and of course, more power. One design tweak made a huge impact: a 33k ohm slope resistor and a 470pf treble capacitor. This increased overall gain, slice and punch… mission accomplished.

’80S ‘JOSE’

The ‘Jose’ mod isn’t actually one particular mod but a number of circuit tweaks that players were having done to their Plexis back in the day. One thing is for sure, players wanted MORE GAIN and DISTORTION and some of Jose’s mods, cascading preamp tube stages and clipping diodes sure made a lot of people happy!


FX Loop, Bias Test Points, Variable Slave Output



The KS 6VEL gives you an all-tube effects loop optimized for pedals as well as rack-mountable gear. You can assign the FX Loop to the Switching Bus to bring it under remote control.



The KS 6VEL features external multi-meter test points and a fixed-bias adjustment control so you can optimize your power tubes for the best tone and longest tube life.



The KS 6VEL features a multiple speaker output impedances for compatibility with various speaker cabinets or reactive load boxes.


Foot Switchable Scene Changes are a Snap

4 Button Pro Footswitch


The 4 Button Pro gives you total command over Channel Selection, Preamp Gain, FX Loop Bypass and Solo Boost with a single button assigned to each feature. Should you feel the urge to stack features on one button, the on-board toggle switches let you assign those parameters over to the FS Bus button (far right).
