I had an extension added to my bass... The only thing I do NOT love about it is when playing pizz jazz, I dont get that same heavly growl out of hitting an open E when the E lock is in place... know what I mean? It doesnt lock as tight, I have to tighten it every now and then...
The extension was added by my luthier in miami florida, paris banchetti (spelling?)
Here is a pic of the extension...
