Introduction
The BLACKSTAR HT-5RH MKII is a professional, high-performance 5-watt all-tube guitar amplifier head designed to deliver rich, fully saturated valve tone and organic warmth at comfortable volume levels. Engineered specifically for home studio recording, late-night practices, and mobile music creators, this compact "lunchbox" head combines classic push-pull tube design with versatile modern features, fitting beautifully into clean desktop workspaces and portable live performance rigs.
Main Features
The defining strength of the BLACKSTAR HT-5RH MKII lies in its unique low-power push-pull tube design and dual-channel preamp versatility. Driven by an ECC83 (12AX7) preamp tube and a specialized 12BH7 power tube, the analog circuit successfully recreates the rich harmonic compression, natural sag, and physical feel of a massive 100-watt valve amplifier, but at a comfortable volume level that will not disturb those around you.
The preamp is equipped with two distinct, footswitchable channels: Clean (which offers two distinct voices: American style and British style) and Overdrive (which offers two distinct voicings: Classic overdrive and modern High-Gain). For intuitive tone-shaping, the EQ section features a full 3-band equalizer paired with Blackstar's patented ISF (Infinite Shape Feature). Sweeping this single control knob allows you to seamlessly blend your tone stack from a tight, focused American-style voice (with scooped mids and a tight low-end) to a warm, woody British-style sound.
To add spaciousness and ambient depth to your dry signal, the head features a premium, studio-quality digital reverb. For silent practicing and direct tracking, the top-mounted 1/4-inch combined Headphone/Speaker Emulated output simulates the physical acoustics of a miked-up speaker cabinet in incredible detail, which is also available on a balanced XLR DI output and direct USB audio out for zero-latency recording without an interface. A built-in power reduction switch scales the output from 5 watts down to a bedroom-friendly 0.5 watts.
Usage Scenarios
- Studio: Reclaim desktop workspace and record direct-to-board, tube-saturated guitar tracks by running the emulated line output or USB out straight to your audio interface.
- Live performance: Transport an ultra-portable, lightweight 5.6 kg tube head easily to intimate acoustic stages, smaller venues, or backstage warm-up areas.
- Practice: Run silent late-night practice sessions in apartments using the direct headphone jack without losing any of your amp's natural tone.
- Recording: Record rich, harmonically complex tube overdrives, utilizing the built-in warm digital reverb and clean effects loop.
- Education: Instruct students on basic EQ structures and gain staging, demonstrating the seamless sweep of the patented ISF control.

CK Music Staff Recommendation
The CK Music team recommends the BLACKSTAR HT-5RH MKII for guitarists, home recording engineers, and bedroom hobbyists who want the genuine touch response, dynamic sag, and organic warmth of a real tube amplifier but need to practice and record at low volume levels. Standard digital modeling amplifiers can be overwhelming and often flatten your guitar's natural touch, while full-sized tube combos are extremely heavy and too loud for domestic spaces. The Blackstar HT-5RH MKII completely solves these limitations. By matching a genuine ECC83 and 12BH7 push-pull tube circuit with an on-board series effects loop, a direct USB audio recording output, and a high-definition cabinet simulator, it acts as an exceptionally smart, reliable, and value-packed practicing workstation.
