weezerboy Posted September 7, 2003 Report Share Posted September 7, 2003 just got the ibanez back and there isn't a great deal of difference but there is some kind of change, it doesn't help that the minimum requirements of the device is 8kilo ohms and my pickups are 7.5kilo ohms. but from what i've heard it doesn't really work anyway, but at least my guitar tech was impressed, but then again he is a stoner with one eye! + one last thing if the output of the pickup was about 15kilo ohms would it work a lot better? ps. just started a-level music tech and boy is that fun!! plus i got my GCSE results and i got 9 GCSE's!!!

Jehle Posted September 8, 2003 Report Share Posted September 8, 2003 Well I may have to go back to the drawing board on them, not silent just been busy flipping through the forum and other site's. Yes your right about them being a pair of switching diodes. On the other hand I've been chatting with a local guitar freak here that's got a solution for doing the same thing to active pickup's. Thats in the work now and I know a few of those will be going to Wes for sure to play with......... BTW it's fiberglass resin not playdoh syxxstring I hope your's show up as well but if they don't , don't worry I'll send you out part of the next batch since this things gotta be worked out and I definately want real opinions once they work well. Seems like a standard "dumb" diode has an activation voltage of around 0.7 volts. That's way too high for a humbucker (which pumps out about 350 mV, if I recall). Checks through the internet... YES! http://www.teamnovak.com/Tech_info/more%20...fo/SCHOTTKY.HTM You would probably have better luck with the Schottky diode which activates around 150 mV. The humbucker should be nice and clippy going through one of those. Time to make a trip to Radio Shack! Quote Link to comment Share on other sites More sharing options...
Roli Posted September 8, 2003 Report Share Posted September 8, 2003 Silicon diode's got 0.7 V, Germanium diode's got 0.3 V activation voltage, and they've got a much more "softer" clipping curve. But these things are already realized in distortion pedals. Quote Link to comment Share on other sites More sharing options...
Saber Posted September 8, 2003 Report Share Posted September 8, 2003 I just thought of another approach. This would use a small audio transformer, probably like the ones in those 1/4"phono-to-XLR adapters with impedance matching transformers, or the small audio output transformers that they have at Radio Shack (something like 1k:8ohm). The pickup signal would be applied through the "tone" pot to the Lo-Z side of the transformer which would step up the voltage to the Hi-Z side for better clipping by the diodes. As a result the effect of clipping would return back through the transformer as a reflected impedance so that the pickup would "see" a clipping voltage that's much lower than the actual 0.3 volts of the germanium diodes. One detail that I forgot to put in the drawing is that the final clipped signal is taken across the pickup coil. What do you think of my crazy idea?

syxxstring Posted December 11, 2003 Report Share Posted December 11, 2003 hmmm wonder whats in there? So its been awhile and i just saw this out there. Quote Link to comment Share on other sites More sharing options...
Brian Posted December 12, 2003 Author Report Share Posted December 12, 2003 Too funny, the switching diodes need to be wrapped beside each other and facing oppisite directions so no matter which way you install it the signal has the proper way to travel. Just a hint Quote Link to comment Share on other sites More sharing options...
syxxstring Posted December 12, 2003 Report Share Posted December 12, 2003 I bought one for $1 hoping there's part numbers on there, IF so ill post them. Quote Link to comment Share on other sites More sharing options...
Guest Litchfield Custom Gutars Posted December 13, 2003 Report Share Posted December 13, 2003 I'll volunteer for the next batch! Quote Link to comment Share on other sites More sharing options...
ansil Posted January 30, 2004 Report Share Posted January 30, 2004 so brian dude whats the outcome????? Quote Link to comment Share on other sites More sharing options...
weezerboy Posted January 30, 2004 Report Share Posted January 30, 2004 mine works extremely well..although at the time i didn;t notice it but thats because i was in my 100% gain/ noise mode now i know that its great nice mild crunch and i have two left and i'm putting them in anything that i upgrade the p'ups in Quote Link to comment Share on other sites More sharing options...
BMXGUY Posted January 30, 2004 Report Share Posted January 30, 2004 do those ones for like a dollar on ebay work and are they the same design as this, if so which is the best one i think theres 3 different styles that one guy sells thanks the address for his stuff is http://cgi6.ebay.com/ws/eBayISAPI.dll?View...&sort=3&rows=50 Quote Link to comment Share on other sites More sharing options...
syxxstring Posted January 30, 2004 Report Share Posted January 30, 2004 I havent tried mine yet, ill probably put it in tonight. Quote Link to comment Share on other sites More sharing options...
BMXGUY Posted January 30, 2004 Report Share Posted January 30, 2004 which one is yours Quote Link to comment Share on other sites More sharing options...
Brian Posted January 30, 2004 Author Report Share Posted January 30, 2004 so brian dude whats the outcome????? I think I originally used the wrong diodes, for some people it worked but for most it failed. I'm going to get another batch going as soon as I can run down the correct size and of course I'll provide free samples to a few when that happens but don't look for it in the near future. It will probably be a few weeks off. Quote Link to comment Share on other sites More sharing options...
