First off, let me tell you that I'm a beginner. That being said, I own a Hamer Slammer with two pick ups. Both pick ups have screws on top and bottom, standard I presume. The method I'm learning has me resting my thumb on top of the front pick up when strumming the E and A string. The screw on top of the front pick up is starting to get on my nerves, I can feel it when resting my thumb on it. Am I putting too much pressure on my thumb? Seems like they could have used something else to secure the pick up knowing that the thumb would be resting on it quite frequently? Anybody else share the same views? Thanks anyone for advice.
