I have a Steinberger GL-4TW serial no. 5702 in excellent condition. I have the original soft case but not the trem arm or battery cover. Frets shows some wear but still have life. I have verified with Gibson that this is indeed a GL-4TW shipped from the Newburgh, NY factory on 4-29-1988. I'd like to gauge interest and relative value in the current market before officially putting it up for sale. If you have any info or input you'd like to share with me I'd greatly appreciate it. Thanks for checking out this very excellent guitar, you have good taste my friend.
