Just got a Planet Waves NS Mini Headstock Tuner and man, it barely fits on my Stammie headstock. Its a "classical" style headstock, custom bass. I have to more or less force the clamp wider than its supposed to go to get it on. I love the tuner as it means I can pretty much just go cable > bass > amp. Any suggestions as to other means of getting this unit to stay on securely? I suppose double-sided tape might work, but then I am guessing the tuner wouldnt pick up the vibrations of the bass properly.
