The Blackstar HT-5RH MK III is a 5-watt tube guitar amplifier head for practice, recording and smaller gigs through a cabinet of your choice. A 12BH7 power tube runs in a push-pull design with an ECC83 in the preamp, and a power switch drops the output to 0.5 watts so the tubes can work hard at low volume. Two channels with two voices each, Blackstar's patented ISF tone control, reverb and CabRig speaker emulation on the XLR, headphone and USB-C outputs cover everything from quiet practice to direct recording.

Two Channels, Four Voices

The Clean channel has its own Volume and Tone controls. Its Voice switch changes between an American voice that stays bright with a tight low end and a British voice with looser bass, warmer mids and a strong response to your picking. The Overdrive channel has Gain and Volume controls and two voices of its own: a hot-rodded classic overdrive, and a modern voice with a mid-focused boost and a looser, more aggressive feel. Both channels share the Bass, Middle and Treble controls and Blackstar's patented ISF, which moves the tone stack between an American and a British response. The included 2-button footswitch selects both channels and both voices.

Recording and Practice

CabRig, an IR-based cabinet simulator with three stored patches on a rear-panel switch, feeds the balanced XLR DI output, the stereo Line Out / Phones jack and the USB-C audio output. The XLR and headphone outputs keep working in standby, so you can record or practice silently with no speaker connected. Over USB-C the amp appears as an audio device in your recording software, plug and play on a Mac and with Blackstar's driver on Windows, and Blackstar's Architect software edits the CabRig patches and sets a separate reverb decay for each channel. An effects loop with a +4 dBV / -10 dBV level switch takes studio processors or pedals, and a 3.5 mm Line In lets you play along with music.
