DIAMOND QTL1 – QUANTUM LEAP

The Quantum Leap…. a tone toolkit of short delays. The QL offers lo res delays, flanging and chorusing effects as well as fixed comb filters – effects that are both great on their own, and also as an invaluable ‘companion’ to other analog or digital delays.

By utilizing the same variable sample rate concept used in analog bucket brigade modulation, and adding custom analog anti-aliasing and reconstruction filters and companding, we’ve captured the essence of analog modulation and delays… in a small footprint, with advanced control features, and standard 9V powering. First used in the Memory Lane Junior, the Quantum Leap digital sampling engine’s sole function is to copy, delay, and reproduce the delay path signal with no mathematical manipulation at all* – and unlike standard audio codecs, there are no digital anti-aliasing and reconstruction filters. All signal paths around the sampling engine (direct path, feedback path, and everything before and after the digital sampler) are analog, paths carefully designed to provide a unique sonic signature that is unmistakably Diamond.

well, almost no manipulation at all….in the QL’s Tap Delay mode there is a tiny bit of signal processing to get the delay ‘wash’ sound.

Quantum Leap audio clips:

  • Clean Strat Arpeggio – Delay Wash – Tap Delay ‘wash’ mode, Speed: 9 / Width: 10:30 / Regen: 1 / Mix: 12 noon. Guitar: 57 relic strat, Amp: 57 deluxe reissue. No effect intro, then QL
  • Clean Strat Chord – Delay Wash – Tap Delay ‘wash’ mode, Speed: 9 / Width: 11:30 / Regen: 11 / Mix: 10. Guitar: 57 relic strat, Amp: 57 deluxe reissue. No effect intro, then QL
  • Clean Strat Flange – Flange mode, Speed: 11 / Width: 4:30 / Regen: 12:30 / Mix: 2:30. Guitar: 57 relic strat, Amp: 57 deluxe reissue. No effect intro, then QL
  • Clean Strat Chorus – Chorus mode, Speed: 1 / Width: 12 / Regen: 10:30 / Mix: 12 noon. Guitar: 57 relic strat, Amp: 57 deluxe reissue. No effect intro, then QL
  • Harmonic Delay – here we use two different QL’s with two different mode settings – harmonic delay and modulated delay – plus an MLJr, Trem and Comp in the chain. Guitar: Gibson SG, Amp: Maz Jr NR
  • Muzak – a GarageBand backed set of guitar parts using the Quantum Leap. Left to right you can hear a) clean strat w/Quantum Leap in delay mode b) clean strat w/Quantum Leap using ‘controlled feedback mode delay’ c) clean strat w/Quantum Leap pitch shift and ‘controlled feedback mode’ delay d) Cornerstone distorted strat w/Quantum Leap in delay mode. All guitar parts recorded through a Maz 18 Jr NR. The clip showcases how the foot controllable pitch shift mode can be used to add atmosphere to a track.
