I recently purchased a Epiphone Accubass for $30. I travel a lot and wanted a beater bass to disassemble and pack in my luggage. I am not concerned with theft or damage. The neck however has a slight twist to the E side, high action from the E, lower to the G. It's playable and I don't want to invest a lot of money fixing the twist. Can a neck twist be resolved to a straight neck without replacing the neck?
