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 upgrade kit covers the Black Star HT5 Metal combo and HT5 Metal head and is designed to provide a bright punchy tone with a thick grungy and distorted sound when pushed. We use a combination of the best of the current production and new old stock items to achieve this.
The Harma 7025 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.
Black Star uses a 12BH7A as the output valve and in this kit we use the new old stock American made 12BH7A.The reason we have chosen this valve is for the way it handles saturated signals.
The valve has a very detailed mid band which is not overblown or heavy, which suits the metal player. When pushed into distortion and overdrive the Philips 12BH7A has a full creamy overdriven sound with a crunchy aggressive edge. The bass end is very tight and full with plenty of definition preventing the mush that is displayed with the stock valves.
The kit consists of
1 Specially Selected Harma ECC83-7025 Dr 250
1 Specially Selected Philips 12BH7A
Please note that the kit is for the valves only.
