I find it hard to believe that a manufacturer of, what many of us would consider to be, a quality instrument is not prepared to make good on defects with their products - irrespective of whether the defect was theirs or the client's.
This is a very competitive market with many basses in a similar price bracket - surely reputation is everything - as a potential customer, if I knew that a particular brand was prone to problems I'd steer clear. Historically, Jaydee had some issues with necks but stood tall and addressed the problem so that subsequent basses did not have the same issues.
I believe the major cost to Maruszczyk would be time - not expensive materials - however the possible cost in loss of sales/ damage to the reputation easily exceeds any costs.
From what I've read here I would certainly think twice about buying one - and I like the design!
Come on Adrian, do the right thing - make good on this whether it was the owner's negligence or not. I'm sure that many potential customers would find this level of customer service reassuring when placing an order. Surely the desired outcome is one where is everybody is happy.
