The Burpster Posted November 30, 2008 Share Posted November 30, 2008 Dave, What is the cause of microphony on single coil pups? can it be rectified? Is it amplifed by a pre-amp (proprtianally) or does it just make the problem louder? Is there a test I can preform to identify if this is the problem as opposed to just very sensitive pick ups....? Help please.... (cant find any tech reading on this!) Bob Quote Link to comment Share on other sites More sharing options...

Help please.... (cant find any tech reading on this!) Bob[/quote] Very good reply from ahpook on this. microphony in valves and pick ups is caused by something moving that should not be. Not sure how to test a pick up but it might be the same as a valve, just tap it with something wooden, lolly-stick that sort of thing. If you hear the tap via the amp and it rings then all is not well. Quote Link to comment Share on other sites More sharing options...
The Burpster Posted November 30, 2008 Author Share Posted November 30, 2008 Excellent replies, thanks fellas.... I believe I know what the problem is now..... I'll just have to give it some thought...! Thanks again. Bob. Quote Link to comment Share on other sites More sharing options...
The Burpster Posted December 9, 2008 Author Share Posted December 9, 2008 Dave... Sorted it thank you.. The pup has a central blade that can be removed from teh plastic housing. This blade had a sliver of the earth brading from the shielded wire runnig up inside the cavity and sat between teh magnet and blade. This was causing the two parts to rock... So took out both parts of the blade and stuck them together with very thin double sided tape and soldered a piece of copper foil to the shielding and that sits alongide the blade in the cavity now..... Job sorted, two very happy non microphonic humbucking pups now. Thx for putting me on the right track..! Quote Link to comment Share on other sites More sharing options...
