Blackstar HT-1R MkIII
Blackstar · amplifier
The Blackstar HT-1R MkIII is a 1-watt all-tube guitar combo amplifier, one of the few commercially available all-valve designs at this wattage. It uses a 12AX7 preamp tube and an ECC82 power tube to deliver genuine valve character at bedroom volumes. The MkIII revision added USB audio interface output, improved reverb, and a CabRig-based speaker emulation system. A headphone output and direct-recording capability make it practical for silent practice and home studio use.
