Blackstar HT-1R

The Blackstar HT-1R is a 1-Watt all-valve guitar combo amplifier engineered to deliver authentic tube tone at low volume levels, making it ideal for home practice and studio recording. It features a unique push-pull power amp design using ECC83 and ECC82 valves to replicate the harmonic response and dynamic break-up of high-powered valve amplifiers. The amplifier includes two channels (Clean and Overdrive), Blackstar’s patented ISF (Infinite Shape Feature) for flexible tonal shaping, and digital reverb for added depth. With a built-in speaker-emulated output and line input, the HT-1R provides versatile connectivity for recording, silent practice, and jamming with external audio sources.
