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 blues breaker solos with John Mayall, to the powerhouse slam of Jimmy Page in Led Zeppelin to Steve Jones awesome sound with his JCM800. Now the Magic of Marshall little Class 5 head and combo can be improved with our special cryo sets. I know I had hours of fun with my own class 5 Marshall putting these kits together and these are designed to enable you to get the best out of your particular amplifier.
The Marshall Class 5 Classic Cryo upgrade kit fitted with a Celestion 10 inch greenback is designed to provide the ideal combination for those who demand a tight bass response with a warm creamy mid-range and a smooth vintage style top-end.

It is an effective upgrade over the stock Celestion speaker as it provides a more authentic rock sound. This in conjunction with the Harma Cryo Retros added warmth makes this an excellent upgrade ideally suited to Rock through to Jazz. The kit is designed to give you as close to the old Mullard tone as possible and the classic British Marshall sound.

We use a combination of the best of the current production items to achieve this.

The Harma ECC83 Retro Cryo provides a harmonically rich and detailed sound with excellent 3D midrange warmth. This valve has a traditional British voiced sound that has a huge singing sustaining tone when overdriven. The outstanding feature of this valve is its smooth linear midrange response and extended frequency response so you get smooth warm overdrive with tight fat punchy lows.

The Harma EL84 Retro Cryo has a deep well defined tight bass that produces the classic slam of the Mullard in the bottom end. The midrange performance has been tweaked to provide a warm clear detail at low volumes with clear articulation and smooth even distortion when the amplifier is cranked.

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 Celestion Greenback 10 speaker provides a warm creamy midrange tight bass response. The speaker has a smooth vintage treble response with nice clarity on chords and single notes. In overdriven mode it provides a warm creamy midrange which makes it ideal for rock and blues as well as modern styles of music.

The kit consists of
2 Specially Selected Harma ECC83 Retro Cryo
1 Specially Selected and matched Harma EL84 Retro Cryo
1 Celestion 10 inch Ceramic greenback 10-30 watt 16 Ohm speaker

Please note that this kit contains the valves and speaker only.
