Black Star guitar amplifiers have quite rightly caused a major buzz in the music industry since their launch back in 2007. By upgrading the valves to our selected sets customers have been able to voice their amps to their personal requirements. Customers have reported a range of benefits when upgrading the valves over the factory items. Here we have listed our most common upgrades using current production and the best new old stock items to help you get the most out of these fine Black Star amplifiers.
This 5881 upgrade kit is designed for head which was originally fitted with EL34 or 6L6GC. With a simple re bias of the output valves the head is fitted with new old stock Harma 5881 to suit most hard rock and metal player's demands.

It is designed to provide the classic tight punchy rock sound which is suited to harder rock and metal styles .This will 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 Blackstar offers.

The Harma ECC83 Retro 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 ECC82 Retro 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. This valve adds fatness and midrange warmth to the Blackstar sound.

The Harma 5881 is the button based Russian military valve powered the Marshall and Mesa Boogie amps (STR 425) in the late eighties. The 5881 valve has bullet proof reliability 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.

4 Specially Selected Harma ECC83 Retro
1 Specially Selected & Balanced Harma ECC82 Retro
