grace works quite well as treble boost

[CoolJohnny]

just wanted to let anyone/everyone know i've been getting great results using ROG's grace overdrive as a treble boost. using the stock circuit with the jfet buffer (not necessary but improves the sound drasmatically in my opinion) just drop the .0068uf cap to the input of the LM386 to .001uf, and the output cap from .1uf to .047uf. gain control is the same, but lose the volume pot. it really drives an amp hard (i can actually record my bassman using this circuit with the amp volume all the way down) and is very drynamic and responsive. try chaning the in/out caps, even throw an electro on the output for some interesting sounds...best of luck. whoever designed the LM386, i'd like to buy a beer.
