Hi Rabbit,
Well i could not remedy the stain issue so have to live with it, a lesson learnt for the next build.
Regarding the wiring Simon was a great help in sorting that, all is done except i forgot to run an earth wire to the bridge / tail piece which is tomorrows job along with fitting the strings. All being well it should be finished tomortow night ( dont hold me to it ).
I am looking forward to trying it i currently have a standard size bass as my main instrument, i am looking forward to the lighter weight of the HB-4
