The Blackstar HT-Boost is a tube-driven boost and overdrive pedal designed to enhance dynamics and touch response. Featuring a high voltage gain circuit with cascaded tube gain stages and an ECC83 / 12AX7 valve, it delivers maximum dynamics and tone. It includes all-valve cut and boost tone section with controls for Boost, Bass, and Treble, the HT-Boost also includes a high integrity buffered bypass. Ideal for live performances or recording, the HT-Boost is perfect for guitarists seeking a professional tube-driven boost pedal, but it's size, weight and need for a special power supply may be a drawback for some. The Blackstar LT Boost is a potential alternative.
Guitarists praised the tube sound quality and character of the Blackstar HT-Boost, but some found its size, weight, and power supply requirements to be drawbacks, leading some to opt for smaller, more standard boosts.
