Nirvana is one of those band that just never gets old. You can have year long breaks without listening to them but every time you come back it's like 'oh yeah this is still fucking awesome'. Thanks for the reminder quinn.
It's funny cus I felt the exact same way. But when I was 16 something I pulled the trigger on a les paul and to be frank, everything else is shit to me now. The neck angle, the buttery smooth action, easy access to switches without them being in the way (like on a Strat)
It sure is a guitar that takes some getting used to. The sheer weight and clunkyness of it, but that's a trade off. The feel of quality and pure blissful tones you can get from it is worth it.
I've played a lot of different guitars for prolonged periods of time and even thought about getting a new daily driver, but I can't. I always fall back on the LP.
Oh and it works wonderfully with drop D. I've jammed along to the doom OST and it's pretty stable.
If I was looking to play fast and metal I'd choose an S model ibanez but I guess that's shit advice to you haha. You could upgrade to another S model if you're into it. Some of the high end stuff looks amazing.
