My interest in guitars started around aged seven, when, exploring in the attic as small boys do, I came across my father's arch-top guitar, a 1929 copy of a Gibson L5. Shame it wasn't a real one! It had a beautiful sunburst finish which positively glowed and even though there was no way I could extract anything musical from it then, the addiction was immediate.
I learned to play using that guitar, and in my hands it suffered many ignominies, including nylon strings, and homemade pick-ups (made from a set of WW II ex-army headphones). It was many years later that I rebuilt it and re-set it's sagging neck and passed it on in near perfect condition (despite all my efforts as a teenager) to one of my nephews who had inherited the musical gene.
My interest in guitars was interleaved with interests in sports (particularly sailing) and woodwork, with educational and professional commitments mainly in engineering fields distracting me occasionally. I graduated from Durham University in the UK with a Bachelor's degree in engineering followed by a PhD. I worked post-doc for a while at Cambridge University Engineering Department teaching students the complexities of applied mathematics and electromagnetism (or were they teaching me?). Over that period I built numerous wooden boats and raced them with considerable success. The boat building certainly honed my woodworking skills and the engineering disciplines were ever useful.
Fast forward a few years, with an MBA behind me and a good many years of consulting engineering, I was still playing guitars and sailing boats, but now living in Australia; the result of too many consulting assignments to this part of the world. I bought a cheap secondhand guitar to play on my cheap second hand boat and found it somewhat lacking. The saddle was in the wrong place. Not being sure that there would be enough room in the bridge to re-position the saddle, I wrote a small computer program to figure out where the saddle had to go so that the guitar would play in tune (spot the engineer).
