Vigier Guitars

Hi,

The Neutrik locking jack in my Excalibur Ultra Blues is not work, i.e., it does not lock at all and I can unplug the cable without pushing the red flange effortless.

Is it normal? Does it mean it is broken and I should replace it?

 

Thanks in advance!

<p>Dear Vigier Team,</p> <p>I recently acquired a Vigier Excalibur Indus form 1999 (according to the serial number). I wanted to ask which significant upgrades have been done to excalibur guitars  since then, in particular:</p> <p>- Vibrato model.</p> <p>- Frets material.</p> <p>- Nut material....
