Hi am new here, but ive been hanging out at the BAM forum for a while tho. Just want to ask opinions about this OD pedal. Am planning to buy it as a booster for the crunch channel on my amp (Rivera R30-112). The Rivera has its own booster but to me the sound that the Rivera gives boosted its like there but not there. Just missing the last oomph. Am thinking of getting this pedal to punch the amp over the edge. Does it works well in this regard? Ive also read in HC reviews that when in boosted mode its very easy to get the harmonic squeals ala ZW? Tt true?
