Limited Quantity - Hand Wired - Original Vintage Technology
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.
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
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.
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! Want a
