I havent tried it, but I guess your guess is right. The through is going to put some lows in that arent the norm for maple, cos the guitars going to resonate with lower low modes, the maple itself we all know about, the highs wont change too much...I'd say you'd get a really, really tight (what lows maple does have are very fast indeed) and quite deep, but not overbearing low end and a rather a lot of high mids, highs and clarity.
But thats just a guess from maple throughs with totally different pickups in...the closest I've actually played is maple through with an 81 - this should be similar but with more low end. If you can get hold of a KH2 to try out that wont be a million miles away.
