DOD FX57 Hard Rock Distortion mods

[gringo699c]

Anyone know of any good mods for the DOD FX57 Hard Rock Distortion.
I changed one of the op amps which helped some but this thing still sounds like shi%!
 I coudnt find the schematic anywhere so if anyone has that it would help.
thanks

don't have the scheme anymore but i used a feedbakc loop to keep looping the delay on top of itself
