These are my favorite picks for low tuning 7 and 8 string guitars, great tone, flexible thickness and you have 3 plectrons to use up instead of one. Good pic is everything when it comes to your dream tone, thru my life I found a simple test to find my best, the higher the pitch of sound it creates when you drop it on a table, the better and brighter the sound it creates. This is obviously up to your liking, but for me this pick is a king !!!
