Re: Ibanez JD9 Jet Driver [schematic]

Huh!? You can tell the function of a cap from a photo without being able to see how it's connected? :shock: Of course: the described capacitor is part of the "MID"-control. But I can´t tell you how a change of the value should influence the bass-response. BTW, the capacitor isn´t .0047µF, it is .04...

Re: Carlsbro Suzz Phase 1st - Prototype

.... What I cannot is guess values the type of components hidden under flatcables. Let alone do so from a photo that's too small. This is what I've done so far. Now I want help again. I can´t read this cry for help without acting. Here are the missing parts. For the phaser a look at the MXR Phase 4...

Re: My schematics collection on Skydrive

Some European countries may have enforceable copyright law. Enough countries don't that it preserves the "information wants to be free" idea. 1.) Every country of the european community has enforcable laws. 2.) Europe is a little bit different than the U.S. In europe you acquire the copyright on yo...

Re: My schematics collection on Skydrive

I'm sorry, but Microsoft has canceled my SkyDrive account. The point is that they do not respond to my requests and give me no reason or answer for several weeks. Why should they ? You can find the answer in their terms of use, which you should have read before creating your illegal collection: htt...

Re: Pro Co - Solo

Just modify the last stage (JFET) according to the schematic I attached. It should satisfy your need. "jymaze" wants to proof us, that he is a handicapped theft who is unable to read - it is clearly written in the schematic: " By downloading you agree not to alter this schematic, distribute it on C...
