I've had spinal surgery twice in the last 20 years. The last time was back in May 2023. I had lost feeling in my hands and feet with the most recent issue and had Laminectomy, Laminotomy, Foraminotomy, Laminoplasty. The surgery was very successful in many ways. My pain is totally gone but I still have residual issues with numbness in my hands and feet.
And one of the side effects is that I have been having an incredibly hard time gripping the pick. I thought for a while that it was dryness but I've now determined that I have lost some strength in my right hand's fingers.
A number of manufacturers make picks with holes in them. That doesn't help me. I have been “hole-punching” my picks for years and increasingly, it doesn't help.
There are picks with bumps on them to assist in a better grip but I'm very used to the 346 shape and I literally have hundreds of these picks.
So, I bought some anti-slip tape off of amazon and it works great. (https://www.amazon.com/gp/product/B01MYB5U9A/ref=ppx_yo_dt_b_search_asin_title)
This tape is adhesive backed and it's easy to cut without scissors - which is good because it would ruin them.
I'm very happy with this solution and I feel like, overnight it has improved my technique!
