I have a Jasmine acoustic bass which does its job very well. With a cheap guitar you just ain't gonna get the sound of a pre-war J-45 but a proper set-up job will help as far as playability goes.
That said, Seagull is an ok guitar, but every guitar is different, even within model/years. Play every one they have in the store. One will sound better that the rest. If the store only has one you can play and wants to sell you one in a box "cause that's our floor demonstrator", go elseswhere.
