I notice a prevalence of Strats in this thread which I just had to disrupt with a few more LPs.
My main and favorite guitar is the 2006 Gibson Les Paul Studio Vintage Mahogany in Worn Brown with Gibson Burstbucker Pro pickups and 300k linear pots. I've replaced the stock tuning machines with Hipshot Grip-Locks (which are great) and I also shielded the cavities (which didn't do much, honestly). Over the almost 20 years I've owned it I also replaced the pots a few times and had to level the frets.
I've played *a lot* of LPs over the years and this one remains one of the best I've heard - even if most LP-aficionados might say it is constructed all wrong!
Another guitar I often use is the 2015 Gibson Les Paul Classic in Fireburst finish, with Gibson '57 Classic/Super '57 pickups. The neck profile on this one is very different (60s slim neck vs 50s neck on the Studio, but also wider than normal LP due to the adjustable nut). On this one I've replaced the G-Force robot tuners with standard Hipshot Grip-Locks, the 2015 adjustable brass nut with the Graphtech drop-in replacement, and the 2015 classic 2x volume (push-pull) 1x tone (push-pull) 1x active boost circuit PCB with the standard Gibson 2x volume 2x tone PCB. All of the 'modern' functions that came with the guitar originally were cool, but I decided were liability for live performances - which is why I did the replacements. I guess you could say I'm just a traditional guy (pun intended
)
The next one is an early 2000s Jackson Dinky DX10D, originally solid black, which I've heavily modified over the decades: stripped the poly black paint and repainted it in yellow/black tiger graphic, replaced the Jackson double-locking tremolo with a Schaller one, replaced the stock pickups with Seymour Duncan JB/Jazz, replaced the plastic pickup rings with metal ones and replaced all pots, jack and switch. This one I just use occasionally for the tremolo effects, and usually for a few songs when performing live because it looks cool.
And last (but not least), my late 2000s Martin D16RGT. IMHO a truly amazing-sounding guitar - though I'm far from an amazing acoustic player
I've also built a quasi-Telecaster from various parts and painted it metallic green - but TBH I never really use it.
