Now had two of these units.
First started mis-triggering after a few gigs then finally stopped working. Replacement unit, which had been redesigned, worked fine out the box, then stopped triggering unless played really hard... Utterly hopeless. I now use a looper for playing such sounds. Thomann acted swiftly throughout the returns, and have issued a full refund - blame lies with Shadow for (not) designing an unreliable product...
