I have had clipping issues with my Boss delay and chorus pedals in the V's loop. When talking with Mesa I recall that they said the loop was designed more for line level effects vs. instrument level. I've already tried to cure the problem with the Boss pedals (see other threads I've started or participated in) and so now I'm moving on to something other than Boss. I don't play out often with this amp so I can't justify spending a ton. I noticed the Eventide Timefactor, although outside of my budget for now, has a line-level/instrument level switch. Should I be looking for a switch like this? Should I look at rack mount FX? Are the TC Nova Delays line-level? THX.
