Of all of the basic metal pecals out there, the boss sd-1 is actually one of the better ones. Back to basics works well every time! If you have no presence control, then another option besides the sd-1 would be an overdrive pedal. The MG100DFX has the presence control (mine is th eamp not the cab and head combo), that knob definitely makes a big difference, pity it's not on the 50 watt version. They are not a bad amp at all especially for the price.
