It looks like you have a fantastic collection of amazing guitars. I’m a huge fan of Gibson I own a few. I make a living playing them so they get a lot of stage time but I’m still a little kid grateful to plays guitar.
I love guys like yourself.. myself a Gibson guy but in the bass guitar world.... Constantly experimenting inexperienced and experimenting getting sound getting what I hear getting above all what I feel keep on doing what you're doing.❤
I prefer the M400 actually. Looks like I am about the only one though. Perhaps one needs to be in the same room with them both. They are close to each other but I prefer the slightly warmer tones of the 400. YMMV
It’s the FHC model from the late 50’s. Great pickups for sure. They capture the actual acoustic quality of the guitar better than others in my opinion.
