EA Tremolo mods - stop unwanted clipping / distortion

[grolschie]

I found this post at the bottom of an thread about a different topic, while searching the archives. It solved my clipping problem with the EA trem. I used to have horrible crackly distortion on the peaks of the hardest hit notes with my humbuckers. Many people seem to have this problem with their EA Trems, so I thought that it should have a thread of its own to help with searching the archives.

EA Tremolo Mods

Rev 1.0,  Rob Strand (c) 2001

The EA tremolo has too much gain and this causes the circuit to clip.
These simple mods reduce the gain which prevents clipping.
The behaviour of the circuit is otherwise unchanged.

Mods:

    * change the 12k on the collector to 4k7
    * change the 82k on the base to ground to 150k

Good luck jimbob

Changing two resistors is alot more simple than some of the other solutions.

I have got the same issue.  Could someone please explain how to do this mod?  I don't get the "base and collector" deal.  A picture of the ggg layout with the new mods would be greatly appreciated.

Hey, what improvements are made here? More info would be great.

By the way, for some reason your site doesn't function for me.

Thanks.
