I really want to buy a used Markbass 2x10 combo, but it's out of warranty, and I don't know my behind from an electron (or stream of electrons). Does anyone have any experience getting their Markbass serviced in the US? I have an eerie feeling that, being relatively small and several thousand miles away and relegated to Guitar Scam, I mean Guitar Center, that basic repairs could get pricey. They certainly sound excellent, but I've never dealt with their technicians or customer service before. If anyone has any experience or anecdotal advice, please let me know. Thanks!
