I found the following table on the internet. It's from WWW.hepro-studios.de. I imagine there's no copyright problem as the download was freely available via Google Search.
The original is an A4 page which contains P/up, original echo units used and Echo settings. It also groups some numbers in A, B or C groups to correspond with the settings.
EQ Hz 31.25 62.5 125 250. 500 1000 2000 4000 8000 16000
Sound A -12 -12 -10 -2 0 -2. 7 0 -12 -12
Sound B -12 -12 -10 -10 -2 2 2 -6 -12 -12
Sound C -12 -12 4 2 - 6 -1 8 6 -12. -12
Modn Sound -12 -12 2 1 - 2 4 -3 -8 -8. -12
Sound A is the very early numbers.
Sound B They list Cosy, Peace Pipe perfidy etcS
Sound C they list Dance On. Theme for Young Lovers, Flyngal ect
Modern sound is obvious.
I've programmed my Katana head amp, and the the infamous H&CSE I'm getting some very promising results.
Cheers! Dave
