Blackstar S1-100-MKII Guitar Amplifier Head (Black)

The Series One MK II is a refined and streamlined range designed as the ultimate modern flagship amplifier and cabinet, tailored specifically for the needs of today’s metal guitarists. This evolution of the range marks a significant leap forward in high gain, high performance amplification, with the 4 channel Series One 100 MK II taking centre stage—a high-gain powerhouse engineered for crushingly tight rhythm tones and thick saturated leads, devoid of the unwanted fizz often present in other designs.

Four metal-ready channels with six total voices

Blackstar’s 100 Series One MK2 comes equipped with four footswitchable channels: Clean, Crunch, OD 1, and OD 2. Aimed to satisfy the needs of modern metal guitarists everywhere, these channels run the gamut from crushing gain-drenched chug to liquid leads to cleaner and more subtle characters. Moreover, the Clean channel sports a switch to turn your tone from Warm to Bright, while the Crunch channel’s Super Crunch switch injects your signal with searing high-octane heat. Finished off with two 3-band EQs and ISF controls (one for Clean and Crunch and one for OD 1 and OD 2), the Blackstar 100 Series One MK2 is an immensely versatile tube amplifier head that rewards adventurous tone chasers with a massive range of sounds to explore

Crushing tube tones at any volume

Clocking in at 100 watts, the 100 Series One MK2 running full bore roars with stage-shaking power. It’s a sound to behold, yet our guitarists are equally impressed with this amp’s living-room-appropriate volume thanks to Blackstar’s powerful DPR knob. It allows you to take this amp’s output down from 100 watts to 10 watts, all without compromising an inch on sound, feel, and sag. From jamming out riffs in the bedroom to recording in your basement studio, the Blackstar 100 Series One MK2 gives you the rich saturation and complex harmonics of glowing glass at any volume.

Seamlessly integrates into any stage or studio rig

Need to lay down a few tracks without making a sound? The Blackstar 100 Series One MK2’s rear panel features a speaker-emulated output with 1/4-inch and XLR outs. This handy feature makes late-night and apartment recording a breeze, allowing you to achieve authentic-sounding tones without rattling the windows. What’s more, the 100 Series One MK2’s effects loop cleanly integrates your entire stompbox collection, and you even get a +4dBu/-10dBV pad switch built into the loop. Finished off with variable impedance to connect to any cab and 5-pin MIDI Thru/In jacks to hook into your cutting-edge MIDI-fueled stage rig, the Blackstar 100 Series One MK2 brandishes all the bells and whistles that modern performing and recording guitarists require.
