    Apollo Pro Bass

    I got my apollo pro in golden brown (transparent ash) with solid brass bridge and saddles, and fishman fluence pickups. I have played out with it several times. The sound and sustain are so good and the action is like butter. I love this instrument!

    Oh man, what a beauty! This guitar looks fantastic with it's deep blood red body and snazzy carbon fiber neck and pickguard. The all black hardware looks super as well. It is short and surprisingly light, just a very comfortable and well balanced instrument. It sounds great and plays wonderfully. A very nice addition to my collection and one which will be getting a ton of playing time this year.

    A Valuable Addition

    I had to wait quite a while for it to arrive, and then the screws to assemble it were missing. I finally got it assembled and started playing. It took a few sessions before it would hold the tune. Once I got that worked out, I found it very easy and enjoyable to play. Once I get this off, I think I’ll play it some more!
