Got a Larrivée D-03R and a Godin Kingpin II archtop myself. Started in summer 2019, stopped playing until around June of this year and have been at it since then. Mostly been focusing on covers of Russian songs but I do plan on getting into blues and jazz in the near future...gotta get that music theory down solid
That's the best way. Try 'em all, and you'll find what suits you quick. I discovered Dunlop Tortex picks very quickly. Start with .46s, later moved to .6, before finding I preferred the heavy 1mm. Use those for a few years then switched up to the 1.14mm for no reason other than that I preferred the colour. Been using those for well over a decade now.
I've never been one to get worked up about picks, whatever I can find will almost always work. Some of the great players use all sorts of things. Ed King from Lynyrd Skynyrd used bits of broken sea shells he'd find on the beach. Had a whole bucket full of them that he chipped into a pick shape.
All of that said...I mostly use Dunlop "Max Grip" nylon picks at .73. They are a good one for both electric and acoustic. I have dozens laying all over the house, when they don't get chewed up by the dog or stuck in the vaccuum cleaner.
I usually have a couple in my pocket or in my coin purse. Sad as it is to admit, there's a tiny part of me feels a little bit more rock and roll for having them there among my pocket detritus.
Seashells is an interesting one, I wonder if those had something of the feel of the original, tortoiseshell pics that would, of course, not have been an option by the time Skynyrd were a going concern?
