I still have my Ovation from many years ago. The electronics are shot and it would cost more to buy a new equalizer/preamp then buying a new guitar.
I’ve had to do some minor refretting and replace the 9 volt battery a few times. That’s all I’ve done over the years.
I haven’t had any cracking occur like some Ovations despite being out of the case for long periods of time.
It was the first acoustic (or electric) I owned that consistently stayed in tune at all positions. Not so with my other guitars, strats, jaguar, and telecaster. Had to retune those suckers slightly everytime the wind changed directions.
