Black Star amplifiers have quite rightly caused a major buzz in the music industry since their launch. By upgrading the valves to selected cryogenically treated valve sets customers have noticed the additional benefits such as better clarity, larger and improved sound stage with increased definition under distortion.
Here we have listed our most common upgrades to the Black Star range.
This Blackstar HT Metal 100 5881 Cryo upgrade kit with a simple re bias of the output valves provides the classic tight punchy rock sound which is suited to harder rock and metal styles .This combination is designed to give you the classic British American rock sound that was associated with Mesa and Marshall amplifiers of the 1980's along with the more modern day voicing that the Black star offers.
The Cryo treatment gives a permanent change to the valves performance. The additional benefits such as better clarity, larger and improved sound stage with increased definition under distortion are what the treated valves provide and ensure a lasting improvement to you sound over the untreated items.
The Harma 7025 Cryo is a selected high gain valve that supplies a tight and deep bottom end sound with excellent midrange punch. The top end is clear sound and it has a nice early harmonic crunch.This provides the right amount of top end focus and bottom end slam to satisfy the demands of the metal player.
The Harma ECC82 STR Cryo overdrives very evenly and does not fall apart when you saturate the amplifier. The valve improves the amplifier as it removes the grainy unmusical fuzz that is displayed by many modern ECC82 in the Blackstar.
The Harma 5881 Cryo is the button based Russian military valve that powered the Marshall and Mesa Boogie amps (STR 425) in the late eighties. The 5881 valve has a bullet proof reliability record and proven track record over decades of use in Russian military applications.
The 5881 valve provides a very tight and focused sound which is very punchy. The valve is also very lean in the midrange which makes it an ideal choice if you scoop out the mids. The 5881 is very aggressive sounding when really pushed which is great for metal riffing and chording. Solo guitar and fast runs also cut through the mix and the valve also remains tight with dropped tunings.
This is an excellent choice for hard rock, metal and fusion players in the Black star.

2 Specially Selected Harma 7025 Dr 250 Cryo
1 Specially Selected & Balanced Harma ECC82 STR Cryo
