[sdiy] More on Flanging...

[John L Marshall]

I'm with you Harry. Years ago I obtained a great flange sound with two vinyl
records on two turntables. I matched the gains on the Gates board and then
twiddled the turntable speed. I believe great flanging has little to do with
Hi-Fi or Lo-Fi or noise, or hiss but depends on two matched signals.

Gene,

You weren't putting your thumb on the capstan, were you? The idea is to
slightly drag the outer rim of the feed reel. If you have two tape
recorders, drag one feed reel flange and then the other.


Take care,
John
