That is a touchy little critter to tame, an OBEL will open new horizons of consistent operation for you. If you have an On Board Effects Loop you sent a full blast signal at all times, so that would be what my settings hover around. With a super II split coiled I keep the knobs between noon and 1:00 on everything, mix setting, low setting, regular sweep, adjust the gain and peak as needed, I like the slow setting myself. LP works OK too for a Jerry tone, I think he preferred it,if you use lower frequency strings for the same notes. Your clip light should come on when you strum hard every now and again. A good tone depends on good dynamics too. But seriously, an OBEL is a fine investment to control that bugger if you play in a band or live. Qtron is a fine envelope filter IMO, don't hate it until you have tamed it yet.
