SuperBlock US

Unleash the Power of Classic American Tones

Meet your pedalboard’s new best friend: the Quilter SuperBlock US! This compact yet powerful pedalboard amplifier packs the essence of three legendary American amplifiers into a single, portable unit. Whether you’re on stage, in the studio, or practicing at home, the SuperBlock US delivers the iconic sounds of '57 Tweed, '61 Blonde, and '65 Blackface with unmatched authenticity and versatility.

Three Classic Voices

The SuperBlock US features three distinct voicings that capture the essence of classic American amplifiers:

• 57 Tweed: Experience the mid-forward power and raw grit of this late-'50s workhorse.
• 61 Blonde: Enjoy the bell-like cleans and growling weight under gain that defined the '60s.
• 65 Blackface: Revel in the slightly scooped midrange and velvety highs reminiscent of the golden era of American amps.

Versatile Power Options

Designed for ultimate flexibility, the SuperBlock US can be powered by a 24-volt power supply for a full 25 watts of tube-like power, or by a conventional 9-volt power supply for 1 watt of power—perfect for quieter applications and home practice.

Cab Simulations and FRFR Mode

The SuperBlock US includes two Cab Sims and an FRFR mode on the XLR Out and headphone out, ensuring your tone is always dialed in, whether you’re recording direct or monitoring through headphones. The built-in reverb and effects loop further enhance your sound, making the SuperBlock US a complete solution for any guitarist.

Compact and Portable

Fitting into a slot about the size of a double-width pedal, the SuperBlock US is the most extensible system you can fit on your pedalboard. It’s perfect for fly dates, commutes, or as a replacement for your traditional amp setup.
