You wouldn't regret it.
Mine is 99% ready, hence, I can't tell you what it plays like.
However, the whole custom thing is a route that I would recommend and it's great choosing all the finer details along the way.
Sometimes it's actually difficult working out exactly what you want given so much choice, fortunately you have the benefit of Jonathan's knowledge to help you weigh up the options you're considering.
The guitars I tried in Jonathan's workshop were all top notch.
I tried out the aqua-marine Lion which is on his website..... I've played lots of guitars, but that set the benchmark for singlecuts for me.
If the current owner ever wants to sell it (and he won't) I'd buy it straight away!
