WTT: My 3Mth Old Martin 2K For Kamaka HF-2 (Concert)

Hello, I purchased this uke 3-4 months ago and I like it but it doesnt have the sound I was looking for. Played alongside a Kamaka, IMO the Kamaka has a fuller sound. I have receipts and origional case, as well as a hard case for it. It is in perfect condition. I'm just wondering if theres anyone out there interested in swapping a newish HF-2 for the Martin 2K Soprano. If not thats ok too but I gotta try.

Cheers
