Watch the Duane Allman online guitar lesson by Jeff McErlain from Kings of Tone
A great way to get more gain and volume out of your amp is to smack the front end of it with a boost of some sort. What pedal sounds best for that? Take your pick! It really comes down to personal tastes. But frankly any OD pedal will work as a clean boost. All you need to do is turn down the gain and crank up the volume on the pedal. If the pedal has a tone knob you can set that to taste, this is the classic way to use a OD as a boost pedal.
