Re: Another new 2009 J-Custom available: RG8420ZE
I don't own one but I've tested them. I don't like the looks of the trem (including the oversized trem cavity) and I think the EP and LPE feel better. It's just a matter of preference.
The oversized trem cavity, as someone already pointed here, helps you to access the screws without damaging the guitar... besides that, if you were to replace the bridge, you have the routing ready
But seriously, I have that tremolo on one of my guitars and I've never found a flaw... I guess it's true that you can't teach new tricks to an old dog
No offense. But yeah, I'm like that sometimes, it's hard to get used to new stuff without going back and comparing it to the old one.
