From the post
Here's an interesting LM386-based compressor designed by Brett Robinson (DIYSB member Toney). I found the schematic for this while searching for something else. Apparently there are various incarnations (and names too) of this circuit, but this seems to be the most popular version. Should fit easily in a 1590A, though, I'm not sure about board-mounting the pots. You might have to get creative there...
