Which OD pedal would work best to add fat, thick lows and still retain great articulation with my Matchless C30 and strat? I tend to prefer the second EF86 channel in general. Need opinions... Was thinking of the Barber Burn Unit EQ or the Sparkle Drive for the clean blend function. Any other suggestions? Is mixing the two channels on the Matchless the best way to achieve the thickness while retaining definition? Help!
