I have both. I can't see me getting rid of either.
The Blue Deuce is raspier, which I really like. The slate on the back is unreal. It's better than some calls that are slate only. It's not quiet or hollow sounding and you can get right on it.
The Ghost Maker is higher pitched, but lets me play it softer than I can the Strawser. The slate on the back is also very good.
Both handle pretty much any striker you have with ease.
I have not had a lot of time to play with either, so these are my first impressions. I would say if you want something raspy to go with the Blue Deuce. If you want something without rasp, the Ghost Maker. No matter your choice, I don't think you'll regret it, and probably in time, end up with both. It's hard to beat either of these two siders.
