Hello I'm an old man (58)who's been an air guitarist for years. Last month I decided to buy a Squier Vintage Modified Precision Bass and Warwick Blue cab 60 to learn enough to play along with some of the more basic CD's I have at home. Practisiing the index/middle finger plucking technique like crazy and have discovered a problem, which is I get terrible cramps in the area of the palm of my hand at the top of my thumb. Have others experienced this, will it go when my hands get used to this exercise or is it an age thing? I am not going to give up on this, and would like to learn proper technique, so am reluctant to stop using this method for my right hand. BTW I wish I'd done this y-e-a-r-s ago as it is so much fun!
