Blackstar HT-20 Mk 3 20w Guitar Amp Head

This rugged 20-watt tube guitar amp head delivers rich, expressive valve tone with versatile control and modern connectivity, making it ideal for recording, rehearsal spaces, and small-venue gigs. Featuring two footswitchable channels with dedicated “Voice” controls, you can sculpt tones ranging from pristine cleans to saturated overdrive with Blackstar’s patented ISF (Infinite Shape Feature) for shaping classic American and British-style voicings. Its built-in reverb and 3-band EQ add depth and clarity, while power scaling lets you dial the output down to 2 watts for tube saturation at lower volumes. Studio-ready CabRig cabinet emulation with USB-C, balanced XLR, and headphone outputs simplifies recording and direct tracking without a mic’d cab. Built for tone, flexibility, and expressive playability, this amp head is a reliable centerpiece for guitarists pursuing both classic and modern sonic textures.
