Okay, I didn't read the entire thread. Sorry!
I have to admit, the reason I haven't jumped on a G&L is in large part due to the semi-proprietary design of their components. I've done NO research into this, but then I haven't found motvation to do the research.
I like to change stuff. I'm just not a "plug, play and forget" personality. I'm a definite Leo fan, but I like knowing I can fairly mindlessly go buy "stuff" that'll fit! I also have never purchased any MM products, though I have to admit, I've been peeking at MM porn for years!
Sorry. Fender. It's not the prestige of the name, per se. It's like Chevy or Harley, you can almost find parts at the grocery store!
