Big Jerry G fan and have been playing for about 30 plus years and finally bit the bullet and gave the Fatman's pick of choice a whirl. Very interesting the feel of graphite across the 0.11 - 54 Elixirs on my Strat. Definitely recommend trying them as they are quite unlike any pick I have tried and I have tried dozens of the most common and uncommon across them 30 years.
These make very much sense for how they shaped Garcia's unique tone, mind you, they were but one small component of his multifaceted tone. Not sure when he started playing with these but I totally can see how they fueled his attack on some of the lightning-fast single note runs he would pick individually frequently and particularly when he dug in for those fast flourishes in Jams in stalwarts like Sugaree, Playin and Uncle John's especially
These are excellent comfortable thick picks obviously a little expensive but a delight to play with. I was skeptical at first they would make a big difference after having been a long Dunlop Jazz III XL player but they do. That said I have warmed to the graphite considerably after playing them solidly for the past 2 weeks. As I stated above in relation to Jerry's style, they are great picks in particular for single-note flurries and digging in when soloing as they glide nicely through the strings. I am warming also to them for rhythm but to that end given the thickness not sure how well I will be able to adjust to these for busy funk and bubble picking but will be definitely giving it a go. At this early stage, hard to judge their life span and durability will keep an eye on that and perhaps will comment on that further into the future.
I am not sure I will fully convert to the Adamas picks and leave the Jazz IIIs behind but looks like for the next while they will be my go-to picks to determine whether these will adequately cover the wide breadth of styles I like playing.
All in all, I definitely recommend giving these thick graphite bad boys a go if you are looking to try something different and already clearly gravitate towards the heavier end of picks.
Garcia later.
