The Knob MLT-18 18 watt Handwired Tube Amp

Limited Quantity - Hand Wired - Original Vintage Technology

The Knob is constructed by hand from re-purposed Hewlett Packard designed Tone Generators that were manufactured during the 1960's. Not only is The Knob a functioning piece of art for any vintage tech enthusiast, it is a fantastic sounding amplifier and a conversation starter.

The Knob is an 18 watt Tube Amp powered by a pair of Vintage 6V6 Power Tubes. Its Class A operation offers a robust 18 watts. The power tubes are matched for DC Bias and at Full Power for the utmost in efficiency. The pre-amp side is covered with a Vintage 6SJ7 tube (most often a GE or Sylvania) that helps the amp range from a Fender Style Clean, to Vox-like Overdrive to Classic Cranked up Marshall. The Carbon Composition Resistors and Orange Drop Capacitors are very reliable, provide long life and are very quiet when used in an audio circuit. This seemingly 'no frills' amp has a shocking amount of versatility to it, thanks in part to its 4 position gain switch that allows you dial in just the right amount of gain. The single tone control goes from body to bright.

This amp benefits greatly from using the controls on your guitar to dial in your sound. It's very reactive to a dynamic touch and it cleans up beautifully with just a slight roll off of your volume control. The Knob is an amp that sounds great no matter the pickup you are running into it. In fact, it does a brilliant job at showcasing a variety of pickups. P-90's sound round, snappy and with just the right amount of fuzz. Single coils stay cleaner but they can push the amp to break up when you dig in. Humbuckers go from singing sustain to a wall of power chord thickness that will have you leaving your fuzz and distortion pedals at home. The Knob truly is for the player who plugs directly into their amp, and let's their playing speak for itself.

To up the coolness factor even further, The Knob has several customizable options. They can be built with a 6SJ7 or a 12AU7 for the pre-amp. The 12AU7 provides more gain that comes on quicker. The power section can also be voiced for Bass and Harmonica making this platform incredibly useful across instruments.

In terms of aesthetics, The Knob already has enough going for it but perhaps you're an EVH fan and would like one "Frankensteined" well, that's entirely possible!

Plek Machine
  • Does your guitar buzz when you play certain notes?
  • Do chords sound out of tune when you play them?
  • These are things that can be fixed when you have the frets and neck properly set up. Fine-tuning the neck and frets previously required hours of work by a skilled luthier. Now this can be accomplished in hours using out innovative German-built Plek machine.
  • This incredibly sophisticated, computer-controlled machine scans and evaluates the positions of the strings, string height, and frets along the length of the neck. It then compares the measured result to stored optimum values. It then cuts and smooths the frets and nut to achieve the best playability with minimum string height. The result is a fretboard that feels great with every note ringing out clear and true.
  • The Plek machine can also cut a nut and plane a finger board.
  • Check out our videos and see it in action.
