Keeley Katana Boost

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!
The KATANA CLEAN BOOST! Redesigned, making perfection sound just a bit better!
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!
