Full Description

CabRig DSP technology

The Blackstar HT-5R MkIII 5W Combo features the groundbreaking CabRig DSP technology, delivering unparalleled cabinet, microphone, and room emulation. This innovative feature allows guitarists to explore a vast sonic landscape, perfectly tailoring their sound for any genre or setting. Whether for live performance, recording, or practice, CabRig DSP ensures your tone is rich, detailed, and authentically reproduced, setting a new standard for amplifier versatility.

Power reduction feature

One of the standout features of the HT-5R MkIII is its power reduction capability, which enables the amp to switch from its full 5 Watt power down to 0.5 Watt. This allows players to achieve those highly sought-after valve tones at significantly lower volumes, ideal for practicing in environments where noise levels must be kept to a minimum. This feature ensures that you can enjoy the full dynamic range and expressive character of the amp without compromise, regardless of the setting.

Patented ISF control

At the heart of the HT-5R MkIII's tonal versatility lies Blackstar's patented Infinite Shape Feature (ISF). This unique control allows players to seamlessly sweep from American to British amplification characteristics, and anywhere in between, offering an infinite array of tonal possibilities. The ISF control works in conjunction with the traditional EQ settings to sculpt your perfect sound, enabling precise adjustments that cater to your individual style and preferences.

Two footswitchable channels with voices

The HT-5R MkIII is equipped with two footswitchable channels, each offering two distinct voices, providing a total of four unique tonal options at the tap of a footswitch. This flexibility ensures that players can easily switch from clean to overdrive tones and explore different voice settings within each channel, ideal for live performances and dynamic practice sessions. Whether you're looking for a pristine clean, a warm crunch, or a high-gain roar, the HT-5R MkIII offers accessible and diverse soundscapes tailored to meet the demands of modern guitarists.
