Brand new super limited edition from Keeley - - the highly
sought-after Full sized Katana Clean boost -- in "throwback white" .
Want a mirror image of your tone, only louder? This is it. The Katana
Boost is also a fat, harmonically rich boost, just pull out on the
volume knob and stretch your imagination with overdriven tone! You can
keep it on all the time to push your amp harder, or as an occasional
boost to cut through the mix.
Obsessed or Compelled with the Fattest, Fullest Drive? Well, Before
other people started using Blue LED’s and non-diode clipping stages,
there was the TMB and Katana…. Cascading FET stages do the
tube-amp-thing like nothing else!
The Katana circuit is Robert Keeley’s first guitar effect design for
Keeley Electronics. It was originally designed for Legendary Tones for
the Time Machine Boost but then became an independent product under the
Keeley name after the Compressor came out. Robert’s very first effect
pedal design (1999) was a digitally controlled Analog Delay complete
with built in digital tuner. It worked perfectly and can even be seen at
the shop from time to time. Delay times could be input via a keypad to
enter the amount of delay in milliseconds or by potentiometers. The
Katana is no less stunning in its beautiful simplicity and stunning
sound quality.
Two modes, Pure Clean and High Gain
1. With the speed knob Pushed In, think of it as a volume control that goes to 20.
2. With the speed knob Pulled Out, it’s a cutting boost with a bit of
gain. Not quite an overdrive, just overdriven tube grit and edge to
your tone.
Dual FETs for the most tube like tone in a transistor design. Power
Doubling on the inside so you put 9VDC in, and we use a charge pump to
nearly double operating voltage! (Caution – 9 Volt DC Maximum Input
Voltage (don’t try to put 18 volts to the unit hoping that the doubler
will make it 36VDC!)
What do higher power supply voltage rails mean?! -> SUPER CLEAN
HIGH-HEADROOM BOOST! Pull the Level knob out to switch -> Tube-like
gain! THE EDGE!!!!
