The swivel jack also allows me to ensure I'm not scratching the finish on the guitar (either bottom jack or top jack works).

Just picked up the bass a few months ago and this jack really packs a punch in a small package

I got this to use with a Traveler Ultra-light Guitar for trips and quiet practice ... the jack in the Traveler seems touchy at best, which doesn't help, but even when I was getting good, solid signal, I wasn't too happy with the sound through the VOX.

I caught my headphone cords when I stood up and the device pulled apart which ripped the jack off and a wire on the inside got dislodged (my fault I guess)

I was using the wrong jack.

Others that broke their amp jack were probably exerting too much force

the jack physically came loose, have to wiggle and jiggle to get a connection

This works best if you have a guitar with an jack mounted on the face like an SG or a Stratocaster.

Works as it's supposed to- practice so the world doesnt have to hear.

The volume of the beat machine is also adjustable so you can have it as low or as cranked as you'd like.

This thing is really as great as it gets

This wonderful device allows him to plug his headphones in and play his guitar as loud as he wants, but I never hear a thing.

There are three separate drive channels, as well as, chorus, delay and reverb effects with varying preset degrees of depth.

This is an awesome invention and works exactly as you'd want it to - and beats paying $600 for a Vox amp to plug your headphones into
