For sure! Any hard enough surface will work and yield different results. I find that sanding metal to be more coarse will bring out some additional harmonics and randomness to the sound which is really nice. The tip of this particular screwdriver has a coarse magnetic coating which works in a similar way.
sounds very cool! I dig it!
Thank you for stopping by! Glad you liked it.
Not a screwdriver, but I've used a brass slide to do something similar. It sounds like a "manual Ebow" a bit.
