Just wanted to give a positive pitch for the folks at McMaster-Carr for some outstanding customer service. I ordered some threaded inserts and pickup screws to replace the stripped ones in my bass and got the wrong length. Emailed them to change it, and after a few e.ails got it fixed. Turns out they already shipped the original order. Refunded me the money and I get to keep the order plus they are sending me the correct length. If you have any hardware needs I highly recommend McMaster.com
McMaster Carr is a tad pricey, but the customer service (for questions before ordering) and probably 100 or more orders over the years with no mistakes or mix-ups makes it way worthwhile to keep buying from them.
My last buy from them got porch pirated or otherwise lost and they replaced it immediately with no hassle. I wish I needed more hardware, I'd def give them more biz...
My favorite part about using them is the insanely fast shipping. I don't know what magic they work behind the scenes. Maybe they have a secret warehouse in my back yard. But I will often order from them late in the day and get the package the next morning, using their standard shipping speed. I live in the middle of nowhere! Nothing ever gets here that fast from anyone!
