Excellent product

Had to replace the jack on an Ovation that had issues with the battery connection for the preamp. This was way more jack than was really needed but the price was right and it was excellent quality.

I bought this to replace the jack on a Parker guitar. The ground lug is in a different location on this jack, requiring a small jumper, but the quality is way better than the stock jack in the guitar. Very pleased.

Excellent piece of hardware! I was having trouble finding one anywhere else, and this one is just exactly what I needed. Used it in a 80's Ibanez Roadster. No more crackling noise!

After months of seeking those jacks in local electronic and music stores, i've purchased dozen of them on stewmac. Well - it's right thing, and i'm happy now, just like my customers are. Thanks.
