Upon doing some research, I have found out that some pedals, specificaly the MXR Carbon Copy, can act up in the Tweaker 15 effects loop. The Tweaker 40 and 88 has the instrument/line level switch. Does this mean the Tweaker 40 and 88 do not have this same issue, or is the problem not related to -10/+4 db?
