Reading Justin's recent comments on the pre Shadowmania issues with gear and several other previous postings re echo machines and amps needing the attention of Amanda on gig site begs the comment that these re-furbished vintage units may sound good but are they worth the hassle if you can't rely on them on the night!
I have to say that my TVS3 delivers the sound and can be relied upon to work every time and is probably a lot cheaper than finding a Meazzi, having the alterations made and maintaining it.
Having said all that, I can still understand the appeal of the vintage stuff.
