I was recently lucky enough to aquire a killer TA Cobra from a forumite here (thanks Case!), which is ticking all my boxes. The only thing I wanted to swap out was the existing split-shaft tuners for some locking ones. I emailed TA using the address of their website (which states "We receive large volumes of email each day however so response times may not always be immediate") to ask about what drilling might be required etc. Within an hour I'd exchanged 5 emailed with Tom himself, who'd suggested which ones to go for (Gotoh locking, as they require no mods), and has put a set in the post to me first thing this morning. The price also seems very low, given that it includes shipping to the UK. I'd always heard good things about TA, but it's still nice when you experience it first hand - especially when he's dealing with a guitar not on it's first owner. Kudos, sir.
