Good morning from beautiful San Rafael, Cali. I will be dropping my Hyak off at Alembic in the afternoon. Edwin is totally correct. If the top is good, let it be. You might be opening a can of worms you don't want to eat. Not to mention, you just got the spoiler, play it for a while. Finishes are notoriously difficult to take off, and if you send it to Alembic, if might be there for a while, due to their workload. I tried sending an instrument to another luthier for the same thing and never got it back, hence I am on my way to Alembic to get this Hyak operational. Talk about an expensive way to get a Bass refinished, woof!
