Description

The Quilter Labs SuperBlock UK is a compact powerhouse designed to bring legendary British amp tones right to your pedalboard. This mini amplifier harnesses the essence of three iconic UK amp voicings—JMP, AC Normal, and AC Top Boost—delivering everything from jangly cleans to gritty overdrives. Whether you're playing at home or on stage, the SuperBlock UK offers versatile performance, boasting a comparable power output to a 25-watt tube amp when connected to its included PS-24 power supply. For quieter settings, it can also operate with a standard 9V power supply, producing an impressive 1 watt of sound.

Ideal for both direct and live applications, the SuperBlock UK features two cab simulations and an FRFR mode, accessible via XLR and headphone outputs. This makes it a perfect companion for gigging musicians who need to run directly into a PA system without sacrificing tone. The onboard digital reverb and effects loop allow for seamless integration with your existing pedalboard setup, ensuring your sound can be both expansive and immersive.

Whether you're driving a PA or monitoring directly from your pedalboard, the SuperBlock UK is a reliable and lightweight solution for guitarists seeking authentic British tones in a portable format.

Critic Reviews

Quilter Superblock UK: Huge British Tone. Small Package | Cain Kong

cainkong.com

The Quilter Labs SuperBlock UK delivers impressive British tones in a lightweight package, making it a formidable choice for both stage and studio work. Its three voicings, modeled after iconic amps, provide a satisfying play experience, while onboard effects like reverb and limiter enhance versatility. However, the reverb may require some adjustment to find the sweet spot, and there's a longing for footswitch capabilities to switch channels easily. Ultimately, it shines as a highly portable option for vintage tone enthusiasts, but some users might miss additional control features.
