Ernie Ball Music Man John Petrucci Signature JP6 Various with piezo

Over all this jp is in beautiful condition. I always wanted one and got this one and man they are truely amazing. That said I do not play nearly enough to justify keeping it. I purchased it being told that everything worked flawlessly. That said it does indeed play beautifully, sound output is brilliant and bright. however when using the piezo on the g string there is a weird tone change. Only when the piezo is fully active can I notice it. I never had the guitar setup to see if that would fix it. I used the piezo so rarely that it didn’t affect me. Just wanting full disclosure in this sale. Feel free to ask questions. Otherwise it’s beautiful and a monster.
