My experience is that he will reply to potential customers very quickly but if you have paid and he has to deliver to you, he will avoid your call like the plague. I received my bass bag after several months hassling. It is a good bag, but the customer experience was terrible. I wouldn't send him anything more than a deposit with balance due on receipt of goods. And then, you're risking your deposit.
I'd love to be proved wrong.
Send him an email from another email address, asking for a quote on a new bass - and see how fast he responds!
Jacques if you're reading this, feel free to correct the record. Somehow i don't think that will happen.
