These are specially selected preamp/front end sets for Mesa Boogie owners. The sets consist of specially position selected pre amp valves that have been selected for each position in your Mesa.

We have 4 kits such as Low gain, This to give the maximum clean headroom, Standard gain, to give a warm and fat overdrive and Hi gain to give you maximum over drive with the lowest noise. Our 4 th Kit, called the Classic provides boogie owners with a valve close in tone to the vintage Mullard ECC83. So you can the best set to suit your playing style.

These Cryogenically treated valves are tested and selected to give the best sonic performance out of your Mesa Boogie amplifier.
This Harma STR Cryo upgrade Kit is designed to give your Mesa amplifiers more clarity, smooth warm overdrive with tight fat punchy lows. The Harma ECC83 STR Cryo has the most neutral and balanced sound out of all the current production ECC83/12AX7 types. It has equal amounts of bass, middle and treble so is perfect for many styles of music.

The Harma ECC83 STR Cryo provides exceptional note clarity with improved definition in clean mode. The cryogenic process also removes any hint of harshness from the valves tone and gives the valve far better imaging with more focus and bite. This results in crystal clear cleans and extra bite and rich sustaining harmonics when overdriven via your amp or via pedals.
