wooDi actually is totally unique – its transit-time-correction on low frequencies is a delicious tiny task away from wow!-effects. however it perfectly does its job for those with musical sensitivity. when it comes to ‘electric’ sound, musicians and most engineers think in terms of frequencies and amplitudes, which results in soundcontrol by equalisation and compression. but: the secret of ‘natural’ sound transmission hides in the dynamics of sound dispersion through resonance materials and air boxes. neither eq nor compressor can affect this field. wooDi acts on the time flow of tone, similar to the behaviour of a resonance body.
wooDi is a sound refinement device for amplified acoustic instruments, paired with a high quality Di-box. it’s input section is of high-impedance that works as a perfect preamplifier for any pickup-system. wooDi’s secret is its unique sound refiner – unlike classic tone shapers, its frequency response stays totally flat but gets spread over time. doing so, basses move slower than trebles, and that is exactly what nature does within acoustic instruments. the result is a sweet sound experience of natural acoustics even at high amplification.
wooDi was designed by Rolf Spuler in 2006, based on Ljubos idea and a prototype by Matthias
