DIY PROJECT: TURBO-CHARGE YOUR TR-606 ------------------------------------- This is part 2 of the TR-606 by Geoff Waterston where he shows you an extra modification that builds upon part one which enables you to control the pitch of the 606 bassdrum. Here's the sequel where he shows you the extra modification that can be done that will create a pitchsweep on the bassdrum, and is switched on by the hightom trigger output. He will also show you how to turn the low tom into a 909(ish) bass drum. Finally, we'll do some modifications to the snare drum, which will alter the pitch, noise filter and decay. The construction method is very simple. You just have to solder wires onto the copper side of the PCB and swap capacitor and resistor values; some capacitors are increased in value by soldering another capacitor directly to it on the PCB. Geoff Waterston admits that this is quite a crude method, but it's also very simple and quick.
