So, our band's been getting a lot of notice lately (Top 40 covers, etc) but one thing we keep hearing in our critiques is the dead space in between songs can be too high. I've spent the last few jams & gigs watching the band, to see what's causing it, and the most prominent thing I can see is our lead guitarist's need to retune every time he changes his capo position (or removes it). We've all mentioned this to him, but his excuse is that it's the nature of the guitar and that every one he's had does this. Our rhythm guitar stays in tune through this, but our lead just seems to drop out ALL the time. My guess is that his capo is pushing too hard & bending the strings, throwing the tuning off. What can he do, or what can we have him do, that will fix this? Would changing to a heavier gauge of strings help? He plays a Gibson Les Paul Studio with Ernie Ball Super slinky strings.
