As far as guitar clean boosts go, the Katana is KING TONE. It's the pedal to have for the finishing touch on your tone.
Want a mirror image of your tone, only louder? This is it. The Katana 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.
