i have a ashdown abm500 head. it has the only tuned out in the front. it isnt rack mountable. i love sabine tuners. i just stick it on top of my head and run a cord into the head. i love the way sabines have the led for sharp and flat notes which makes tuning down 1/2 or whatever a breeze. my problem is ive bought around 10 of these tuners in the last 10 years. i get them and they seem to screw up quick. im looking for a good stage tuner that isnt rackmount and is like the sabine (easy sharp/flat tuning) but will last more than a year. any ideas???
