I've been sitting here jacking with the loop on my Roadster. I'm not sure, but it seems to me when I turn the loop on, no effects, it changes the overall tone more than than the effects just put in front. I have a tu-2 tuner, barber tone press, barber direct drive, boss chorus, dd6 delay. The chorus and delay aren't as full, but I can give up a little on those effects. Opinions?
