"Thanks again for another excellent winding job on my last order for a set of bass strings.  The results were outstanding.  The cut-off was exactly 9/16" from the bridge pins for the entire bass section.  The computerized scaling undoubtedly helped.  Well done!"  -- British Columbia

"The bass strings are wonderful!  Thanks for your patience and artistry". -- Ontario
