These specially chosen Cryo pre amp upgrades kits are designed to give what many Marshall owners have wanted for years, Smooth warm crunch with rich harmonics and detail . We have chosen a valve that which gives as close to the classic Mullard 3d midrange tone and smooth even crunch as is possible. We then select these and supply these in special sets for Marshall Owners. Marshall amplifiers are voice of Rock and Roll past, present and in future.These amplifiers have been used by all the music legends. From Clapton's fierce bluesbreaker solos with John Mayall, to the powerhouse slam of Jimmy Page in Led Zeppelin to Steve Jones awesome sound with his JCM800. These Cryo Kits are designed by using specially selected valves and put together to enable you to get the best out of your particular amplifier. These are the closest approach to the original sound.
This 5 valve set is specially selected for Marshall Amplifiers and covers all Marshall Models that have a 5 valve pre amp section with the phase inverter in the V 5 position. These include The JVM series, 800 series with reverb such as 2205, 2210, 4210, 4211 & 4212 with a 5 valve pre amp section.

These sets are for the guitarist who wants the classic Marshall Crunch with that famous Mullard Style harmonically rich 3 dimension midrange response. The valve is made with a smooth response curve so does not have that annoying fizz when the amp is run into saturation which happens with certain ECC83/12AX7 Types.

The Cryo treatment provides warm clear detailed bass with clear articulation and smooth even distortion when the amplifier is overdriven. The highs have more detail, attack and smoothness which can go from a glassy clean to a creamy sustain.
The Cryo process provides more dynamics than the untreated items and therefore provides a warmth and clarity that before was only attainable by using expensive new old stock valves such as the Mullards.

The set consists of 5 valves

4 Specially selected Harma ECC83 Retro Cryo for positions V1 to V4
1 Specially selected and balanced Harma ECC83 Retro Cryo phase splitter for V5

Please note that this kit is for the valves only
