I change strings on my stage guitars every 4 shows ( which probably works out at 6 hours playing time) , I've used most of the big brands at one time or other , and to be honest , haven't found much difference between super slinkies , daddario, or GHS boomers , I don't like the feel of DR coated strings , but all those brands are better sounding than the cheapies . . . . I got a set of nickels "free" with a Bigsby / B7 / vibramate kit , and I thought they "felt" quite nice , and sounded good - since then I've used them for the last few months - I play pretty much classic rock , via a tech 21 Sans amp , into a H K Tubemeistre , straight into the PA - using various Gibson Les Paul's ( with Bigsby's) . I'm really happy with the sound and feel - for the price of strings I'm happy to experiment - Have a try of these , what have you got to loose ?
