Blackstar Series One 45
Blackstar · amplifier
The Blackstar Series One 45 is a 45-watt all-tube guitar amplifier available as both a head and a 2x12 combo. Multiple channels span clean warmth through crunch and high-gain saturation, all shaped by Blackstar's ISF tone control for American-to-British character adjustment. The DPR (Dynamic Power Reduction) system scales the output continuously from full 45 watts down to approximately 4.5 watts, allowing power amp distortion characteristics at manageable stage and studio volumes. The clean channel delivers wide EQ range suited to humbuckers and single-coils alike, with warm bass and generous midrange. Reviewers found it one of the most tonally complete all-in-one tube solutions in its power class.
