I am not fond of tuners that stick out to the side because they do not fit in some hardshell cases. I am also not thrilled with the gear ratio of 10:1 or 12:1 to tune or string up or put in tune. I do not like the additional weight of that much metal on the end of the head. But, without knowing the width of the two outer edges, there may be no other option (such as the internally geared 4:1 PEGHEDS)
Do you have one of the hand cranks for fitting over the button and making tuning easier? That seems to be the only option you have to make tuning, easier, faster, and far less expensive than going to PEGHEDS. **** Completly different....If you have a strap for it, have the top attachment point be at the neck where it attaches to the body rather than way out on the tuner end. It allows you to move the body away from your body to get the sound from the back as well as the front, and makes playing up the neck much easier.
