I've had some questions about thumb picks, and I just wanted to share with you all wich ones I use. My absolute favourite thumb picks are the "Golden Gate" ones.. I used to use Dunlop, but I find the Golden Gate to fit my thumb better. They are very comfortable and have a great sound. Usually, I'll just file them down just a tiny bit, to get them in the length that I like. If you like the Dunlop thumb-picks, I highly recommend trying the Golden Gate picks. They will not hurt your thumb as much!
Hope you have a good day!
