Unique rock tone you can use with your favorite cab.

The Mahalo Katy66 50W tube guitar head is a medium-high gain, master volume, tone monster housed in 13 ply cab. The Katy66 offers a wide gain range and can go from jazz with an edge to serious rock tones. Our unique tone stack makes it easier for your chops to stand out from the crowd. The Katy uses 12AX7 tubes in the preamp and KT66 tubes in the power section. The Katy66 offers beautiful edge of breakup clean tones and will give you hard rock distortion when you push the preamp while still retaining note separation. Hand wired to last and housed in the company's 13-ply cab, Mahalo Amps are ready to tour.
