I biult one and it works great except that when I turn the Highs to minimun it starts sounding like crap, like something is broken. Any toughts?
 
Does this only happen when the Treble/Bass controls are active (Left toggle switch Up), or all the time?

Does flipping the toggle switch on the Right have any effect?

Yes only happens when they are active in preamp mode. Boost mode works well and moving the treble pot does not make any effect
