so i have a dd-20 and my guitarist has the rc-20xl (the loop station, dont know exact model), and were both experiencing crazy volume drops when we kick the pedals on. lemons? or have others noticed this? also, are the trim pots and whatnot that are tweakable for these pedals? every day my respect for boss stuff dwindles....

really need a solution here or were both getting rid of them. cheers
