Hi guys, I am going away from home for a religious festival and won't be able to play guitar for atleast 10-15 days. I have only been playing guitar for about a month now so i am an absolute newbie and don't want to loose what the calluses and a little stretch and strength that i have built. Now I have 2 options. 1. Just leave it, and hope that the calluses won't go away. 2. Buy Planetwaves Verigrip hand exerciser. I have read the reviews about this product and they are pretty good. if any of you guys have any experience with this product please let me know. PS: I would love to hear any more suggestions, tips and tricks. Thank you so much in advance.
