These are specially selected full revalve kits 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 2 pre amp kits, Standard gain, to give a warm and fat overdrive and Our Classic kit provides boogie owners with a valve close in tone to the vintage Mullard ECC83.
In terms of 6L6GC we have selected sets available that will work with the boogies fixed bias arrangement. Certain 6L6GC will be better for certain kinds of music and these we have indicated in our product description.
This Classic Retro EL84 Full upgrade kit is designed to give you a very open and clear top end chime and a rich sustaining tone when overdriven. The valves also have the vintage style 3D midrange warmth which makes this kit ideal for that classic rock sound.The Harma ECC83 Retro outstanding feature is a smooth linear midrange response and extended frequency response. So you get smooth warm overdrive with tight fat punchy lows and that classic Mullard style bottom end.
The EL84 Retro has a deep well defined tight bass that produces the classic slam of the Mullard in the bottom end with the bass being deeper and belter defined. The midrange performance has been tweaked to provide warm clear detail at low volumes with clear articulation and smooth even distortion when the amplifier is cranked.
You will get improvements in such as a crystal clear top end with more extension and clarity when used clean. When using the overdriven settings the valves combined characteristics provide a warm sustaining sound with plenty of upper harmonics with excellent projection on solos.
The valve set produces the ideal combination of warm top end chime with a tight British style bass response with punchy articulate top end sound which does not get hard or harsh when pushed hard at high volumes.
The kit consists of 7 valves
4 Specially Selected Harma ECC83 Retro
1 Specially Selected & Balanced Harma ECC83 Retro in V4
2 Specially Selected Harma EL84 Retros in a matched pair.
Please note that the kit is for the valves only
