You might be interested in reviewing the recent mini discussion re: Correx & the Neuses alternative, which occurred on CAUT, as a response to David Ilvedson's posting of a question to both CAUT and Pianotech: Responses appear under both "correx tension gauge" and "tension gauges". The most informative response I think, came from William 'Bill' Ballard, which, for your convenience, I will reproduce, without permission, here: >Date: Sat, 29 Jul 2006 00:51:59 -0400 >From: william ballard <wbps at vermontel.net> >Subject: Re: [CAUT] tension gauges > >On Jul 28, 2006, at 10:54 PM, David Skolnik wrote: >>Not to belabor the point, but David Ilvedson's question I think >>asked whether the Neuses was as accurate as the Correx.
