Blackstar 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 Blackstar amplifiers.
This Classic Harma Retro upgrade kit is designed to provide a tight driving rock sound with plenty of rich sustain. This combination designed to give you the classic British sound with more top end bite 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 EL34-Retro is based on the famous Mullard EL34 XF2 design and has a number of important features over standard EL34 types. The grids of the tube use a block construction this enables the valve to provide smoother output and eliminating odd order harmonics. The result is a tight bass response with a balanced sound stage and clean clear treble. Thicker glass not only adds strength but also provides lower microphonics. The valve has a slight midrange forwardness giving the sound a full rounded tone when distorted or overdriven. This gives the amp a punchier in your face British sound that some customers prefer and is ideal for Rock and metal giving you a little more edge. The Harma EL34 Retro will suit the vast majority of guitarists from the classic rock player to the hard rock and metal player who want that classic Rock sound.
