Hi Kev, and welcome to the forum, PBG, and the wonderful world of the guitar building ... the best, cheapest and most rewarding form of therapy that there is!

Instructions/measurements for bridge placement? ... most everything that you'll need to know you'll probably find under the forum section "How to Build Your Pit Bull Guitar" in which there a huge number of threads on just about every area of guitar construction (a must read for both beginners and pro's - you never what little tips and tricks you'll pick up in there!) ... but for your initial questions you might want to start with these two threads for bridge placement ...

... definitely give them a read, but the theory is - the distance from the inside of the nut (on the neck/head) to the middle of the fret wire at 12th fret is the same distance as that between the middle of the 12th fret's wire to the bridge (the 12th fret is effectively the middle of the scale) ... getting this position correct will enable you get a perfect intonation "dialled in" when you've completed the guitar and doing its final set-up.

I've not built the ESB-4/4SC so I can't confirm ... but while that model's description seems to indicate that it comes with a T-o-M bridge, the pics of that model show it with what looks like a floating bridge ... a bit confusing, I must admit! ... however, I think that as long as there is a support post underneath the exact position where you'll need to drill the post-holes for the bridge then there shouldn't be a problem (you don't want to only have the thin timber of the soundboard/top of the guitar as the only material taking the strain of the bridge posts! )

Best option though is to speak with Adam if you have any concerns regarding the kit ... or with the resident Guru "DingoBass" (DB for short) for any technical assistance with the build or modifications ... and if its a bass he's all the happier! (all hail to the guru, DB!)

Whereabouts in the "Lone Star" state are you based? ... I spent many months based in the Houston area (a few years back now), and thoroughly enjoyed the time I was there (my favourite US state)... and funnily enough, I found it to be surprisingly just like Australia (the people, their sense of humour and the countryside - except for their accents and the fact that everyone was driving on the wrong side of the road! ) ... and being a biker, you're in good company here, there's number of us "two-wheelers" in the forum.

Don't forget to maintain your build diary as you work through the build - we all love to live vicariously through other people's builds as much as we like to build ourselves ... with lots of pics too (most of us can't read! ... just kidding)

Good luck with it, enjoy it and any questions just throw 'em up on the forum and you'll get plenty of answers!

Cheers, mate.
