I have a Korean Warwick 6 string fretless bass that I enjoy playing but never really loved. I walked in to Guitar Center and they had a NXTa 5 string for a great price so I went ahead and put a down payment on, but cant pick up until the 28th. Im debating trading in the Warwick for the remainder since Im not sure it will get played much after having the NXTa. Any suggestion on what to do here?
