Well, replacement is not exactly what I'm talking about, but for me it would be my ASS MM90, although I still cling to the 2 Pauls at my place (Kim and Mao)...
The JP6 has replaced every guitar I own. Even the ones I co-designed. I still own the other but never play em. They're all just back up until I can get another EBMM.
Sold the Gibson to finance the Morse and never regretted it. Since then I have gone back to music stores with money in my pocket hellbent on buying another Gibson. Trouble is I can't find one I even like. Gibson makes a fine guitar no doubt. It's just that the EBMMs just work to good for me.
