As stated in an earlier post, a regulator is going to help make sure that your gear sees consistent voltage night after night. This client had show dates in Mexico and other places, seemed like good insurance to protect his gear and consistency. The only niggling thing about this piece is the center to center pitch of the 120VAC outs, they do not allow for some typical replacement ends. Shouldn't be a problem if you don't re-terminate your molded plugs or find narrower parts.
First post here, I know or have seen several folks around here on other boards, but to those I don't or haven't, 'Hello'.
All the best,
