The PC-2A is a true vintage studio compressor in a stompbox—there are no cheap VCA chips, opamps or budget components in the signal path which is 100% analogue and built on a hand selected photocell, polyester coupling capacitors, precision resistors (with silver/palladium contacts) and Sylvania N.O.S. (new old stock) 6111 sub-miniature tube operating at real amp plate voltages all on a special silver-plated printed circuit board.
The tube circuitry delivers stacks of head-room and very, very low noise floor for outstanding dynamics, preserving the attack characteristics while creating musical and natural compression—the PC-2A wraps your signal in velvet, enhancing your guitar tone without stamping a solid-state signature on it. Useful in live situations for adding ‘punch’ or fattening up thin single coil pickups and indispensable when recording direct to digital audio workstations (computer) to prevent nasty transient distortion artefacts that modern digital recording devices produce if overloaded.

The Fire Bottle™ is an all-tube booster specially designed to enhance the tone of single coil pickups. With up to 30dB of gain on tap, this powerful boost pedal can push the input stage of a tube amp into beautiful breakup and rich overdrive, creating glassy, bolder, larger-than-life Stevie Ray Vaughan Strat® guitar sounds.

Review by Musiker-Board

The Tube-Vibe™ is a no compromise, innovative and original re-design of the classic Uni-Vibe pedal. However, instead of transistors, the Tube-Vibe utilises vacuum tubes, photocells and a pulsating filament lamp to generate exceptionally rich, swirling chorus and vibrato effects.

The real McCoy! The SR-71 Blackbird™ ‘Tube Tone Engine’ is a genuine all-tube preamp in a compact pedal. Designed for great versatility, the  SR-71 adds additional clean/drive/distortion channels to vintage/boutique guitar amps or works as a professional stand-alone direct recording tube preamplifier. The clean channel possesses a beautifully pure, ‘glassy’ character and audio circuitry within the drive channel is tuned to generate a rich, full-bodied and devastatingly smooth overdrive.

Demo by Brett Kingman

This little green wonder is the world’s smallest tube buffer pedal. Inside is a Sylvania pencil tube operating at 300V, which means the Glass-A™ can effortlessly handle massive signal levels and transients from piezo crystal and high-output active magnetic pickups without distortion for an incredibly open, natural and transparent sound.
