d-basser Posted August 16, 2011 Share Posted August 16, 2011 I have a Boss CS-3 pedal lying around at the moment doing very little good since I find it sucks a lot of bass from the signal and can be a little hissy. I have heard good things about mods such as this [url="http://www.ovnilab.com/articles/cs3modding.shtml"]one[/url] and I was wondering if anyone had tried it, or something similar, and had any advice. I was also wondering about the best place to get components and if anyone had advice on what to get or avoid. Capacitor wise are [url="http://www.rapidonline.com/Electronic-Components/Capacitors/Polyester/Metallised-polyester-capacitor/71096"]these[/url] any good for what I am needing? With the resistors should I be looking at carbon or metal film or does it not matter? Much appreciated. Dan Quote Link to comment Share on other sites More sharing options...
clauster Posted August 16, 2011 Share Posted August 16, 2011 I've just done my second Monte Allums kit on the CS3. First on was the Opto+ mod, this one is the opto mod. The Opto+ had virtually no noise, but went through batteries quicker. As I only use pedals live, the noise isn't that bigger deal for me (and the opto is still a LOT quieter than standard). The kits come with all components, solder and braid and instructions. [url="http://www.monteallums.com/pedal_mods.html#cs3optoPlus"]Monte Allums CS3 mods (scroll down the page for the others)[/url] There's a lot of mods for the CS3. My guitarist who mods a lot of his pedals sent me this list and advice - [quote]Reduce noise: replace 1uf electrolytic caps c4, c14, c17, c6 with 1uf metal film type. R36: change 10k to 100 ohm for more richness and depth. c2: change .027uf to .22uf for more bass. c1: change .027uf to .22uf for more fullness and bottom end. c13: change .047uf to 2uf for more bass (suggests 2 x 1uf metal film caps in series). r5: change 10k to 470 ohm for more body. r32: remove 4.7k and jumper with wire for more clean headroom and brighter LED. d10: remove and jumper for more clean headroom. These mods are for guitars but you could probably use bigger cap values to cater for bass frequencies. Use metal film caps for low noise.[/quote] Quote Link to comment Share on other sites More sharing options...
d-basser Posted August 16, 2011 Author Share Posted August 16, 2011 That list looks like a slightly shorter version of the mod I linked, always good to see people agreeing about what changes to make. Quote Link to comment Share on other sites More sharing options...
