I think the member is talking about a Baretta Special for some 180 bucks. Recommending a J-series or even a Stagey DLX for a first entry level guitar seems somewhat cool but imo is a bit much here.
Fundamentally there´s nothing wrong with a Baretta Special and playing Jazz music with it. But bear in mind that you only have that much tonal options with one pickup. I´d rather go with a Kramer Pacer Classic if it should be a Kramer. But then, there a absolutely no rules as to what guitar is to be used for a specific musical style
BTW: Since you are really started playing recently a swap of the tuners and the trem might be nice to have but at that stage you might you really hear the tonal improvements.
Just my two cents
Practice cures most tone issues.
Great Deals with MrWhipper, JoeyM, Del Hudson, skydive69 and Kramer Classic I
