Studio Gear

Linear Audio Tools for the Recording Studio

Over twenty years ago, London Power began 'The Quiet Revolution' when we introduced the first commercially available guitar tube amplifier with Power Scaling. Our focus has always been to provide thoughtfully designed equipment with extreme versatility, low noise, and the best note articulation possible; to build exemplary products that are at once familiar yet far-reaching in their advancement of the art of guitar amp design; to provide equipment that empowers and inspires the player to new levels of expression and musical satisfaction; and to assure longevity of service that only analog circuitry and discreet-component construction can offer.

We do things linearly, which these days means we are doing things "the hard way". But it is also the way all of the Icons of Tone were built back in the day, so it is truly the best way to produce those beloved tones and the ones that evolved from them.

All London Power studio equipment is designed and built in Canada. Hand assembled. Hand soldered. Hand tested. Specialty tools built by artisans for artisans.

3-D Analog Reverb Systems
$2,430 CND (approx. $1,800 USD) Tube Drive
$2,010 CND (approx. $1,495 USD) Solid-State Drive

London Power's analog reverb units use a full-length Accutronics delay line with either proprietary tube drive and recovery circuitry, or with specially voiced solid-state drive and recovery. All units are 1U. Each is offered with or without LEDs on the front panel, as the aesthetics for home use and for studio use are different.

  • 3-D T     tube drive and recovery, no panel LEDs
  • 3-D TL  tube drive and recovery, with panel LEDs
  • 3-D S    solid-state drive and recovery, no panel LEDs
  • 3-D SL  solid-state drive and recovery, with panel LEDs

London Power 3-D Reverb System from AboveLondon Power's 3-D tube reverb is legendary in its warmth and clarity. Today's 3-D offers this same quality with modern connectivity and now in a smaller package of just 1U. Our proprietary push-pull reverb driver produces warm tube tone but with much greater clarity and lower noise than tradition tube drivers. Recovery of the reverb sound from the full-length Accutronics delay line is all-tube... Read More

3-D Stereo Analog Reverb System (Solid-State, 1U)
In our digital age, many producers and sound engineers want to warm up the sound with analog equipment, but not everyone wants to use tubes to do that. London Power has an all-solid-state version of the 3-D Stereo Analog Reverb System just for them. A full-length Accutronics delay line provides the core sound, with carefully designed and voiced driver and recovery stages... Read More
