Hi my idol, how are you? Marty! Help me, I purchase a strap for my guitar, and when I'm sitting, I can play the licks, but, when I'm standing, the strap of my guitar presses my shoulder, and my hand starts to go numb. Conclusion: I can play the licks just sitting! What I can made to solve my problem? =/ Hugs Marty.

This MAY mean that your shoulder and upper arm muscles are not strong enough to hold the weight of your guitar. Try doing a little LIGHT weight training, concentrating on your upper arms and shoulder area. If you are really going numb, you should probably see a doctor or chiropractor first. Best of luck.
