Play for myself and at BBqs etc with friends and Family , im thinking of upgrading to a better guitar can anyone recommend a next level guitar, I was looking at a FG720s as a start…but am open to any suggetions..would want to spend around £250 to £250.00
I know its a dumb question but cant find a music shop near me to try one out , so can anyone tell me if the extra money ie £150.00 would be worth it???
