Electro Harmonix Small Stone - Mod




[ Zoom ]


This is an Electro Harmonix Small Stone a prety nice Phaser that I modified according to some mods previously published on Internet.

I added to it the by-pass 3PDT switch (see pic 3) wich is a great change in sound for sure and also I added a mix pote (100k LIN) removing the 27K resistor close to the .1uf capacitor at the output.
Then I placed that resitor in the pote's right lug (see pic 2) and short circuited the remaining pair of lugs with a cable. Then both cables were soldered in place of the 27k resistor holes, that's it.
