Personally, I think Grovers make them sound better. But that's just me.
I just had too many of the Klusons slip or fall apart on me over the years.
Having a plain top is more of a price deduction. Personally, I think Grovers make them sound better. But that's just me.
I've never had a Kluson fall apart, and very rarely have I had one slip. :hmm
Obviously results vary, but after three fell apart, or died while I was playing a club, I switched to Grovers. Never had a problem with it after that.
I have probably lived a bless life.* :jim
* At least, in this one instance. :hee
May I ask which qualities of the sound you feel improve when using Grovers as opposed to Kluson and why ? Genuine curiosity here.
I have had more than one fall apart. One of my black Les Pauls has a repaired Kluson on it now, but I'm not sure which one. It fell apart during a gig and a guitar tech super-glued the back cover to the base. It made it through the show and I never thought much about it until now.
