Martin Active Jack - $60 (East mesa)

QR Code Link to This Post

Martin Active jack. I mounted this in a plastic box with a ¼’’ input jack and a ¼” output jack. I did this so I could use this with any stringed instrument with a passive piezeo pick up. Piezeos sound very bad (low output,thin and brittle) without a preamp like this. I no longer play guitar so I’m getting rid of stuff. If this ad is still up, it is still for sale. Thanks. $60.00
