1989 Ibanez Universe 7-strings are most stable, toneful, thinnest neck, lowest action and best sounding 7-strings out there. I’ve owned and rarely played it over the last 24 years. Serial No. F913398. Late 80’s Ibanez necks are the thinnest and fastest necks, and I prefer them over early 90’s Ibanez necks. This is the legendary Wizard I neck era, and 1987-89 are more desirable than 1990-92 guitars, consequently they are worth significantly more due to their playability. This one has no cracks behind the nut nor in the neck pocket. It is in excellent shape. Let the pics be your guide. This same item is also listed for less on Reverb. Case included.
