Quilter Labs' SuperBlock series aims to pack big amp power and versatility into pedal formats
SuperBlock US and UK designs offer a range of American and British-style tones at 25- and one-watt options

Quilter Labs has made a habit of packing lots of power into small enclosures – see the OverDrive 202, a 200W, two-channel guitar amp that can fit in the pocket of a gig bag – and now the company has gone small once again with the SuperBlock US and SuperBlock UK pedal-format amplifiers.
The SuperBlock US features the same three voices – Tweed, Blonde and Blackface era American – as the company’s Aviator Cub amp.
The SuperBlock UK, meanwhile, boasts three entirely new voices – 1979 JMP, AC Norm and AC Top, with the latter two being Quilter’s first amps to feature AC voicings.
Both SuperBlocks function as 25-watt tube amps when powered by the included PS-24 power supply, and can also be transformed into one-watt amps via a conventional 9V power supply.
Other features include XLR and headphone outputs with two switchable cab sims and FRFR mode, an onboard limiter, digital reverb and three-band EQ.
The SuperBlock Us and SuperBlock UK are available for $249 each. For more information, head to Quilter Labs.
