I've been eye some 3M copper shielding tape (#1181) and wondering if anyone has tried it and what your results were? http://products3.3m.com/catalog/us/en001/utilities_telecom/oem_electrical/node_5GDTBB579Qbe/root_GST1T4S9TCgv/vroot_GSHBRQT7DVge/gvel_BBGZX3B1QGgl/theme_us_oemeletrical_3_0/command_AbcPageHandler/output_html It's solderable and conductive through the adhesive that should allow it to work like a charm. Comes in rolls of 1" x 54 feet, which should be enough to shield 4-5 guitars and the width lends itself to tight spaces w/o too much cutting. Found it for $19 + shipping. I guess my biggest question is whether or not the adhesive will adhere to the wood, poly and other surfaces in the control and pickup cavities. It's made to stick to smooth surfaces, but I don't know if guitar cavities are smooth enough. Any help appreciated.
