No bass overdrive or distortion pedal seemed to fulfill my expectations so I bought a boss metalzone pedal which turned out to be exactly what I needed... The problem is that being a guitar pedal as expected the lows are gone every time I step on its footswitch... I probably need another pedal in order to kinda boost the way it sounds... The question is: "which one?"... Anyone who has an obvious solution to this matter on his mind please just post something...

pointless, you should go slap yourself.
