Greetings - First up, I am a big Markbass fan. However, I'm really on the fence about paying the extra $$$ for the GC extended warranty on my new Markbass purchase and am looking for honest opinions/feedback/etc.: granted that new Markbass products come with the excellent 2-year replacement warranty which apparently starts after the Guitar Center 30-day return thing; also granted that Markbass products seemingly have had a very low "failure" rate so far. Taking these 2 factors into consideration, what do people really think about purchasing the extra "GC Performance Guarantee" ad-on that adds an additional year or 2 (buyer's choice) of warranty coverage? Good idea? If you think so, why? Waste of money? If you think so, why? Sorry, but I really need help on this... Thanks!!
