Thanks mate. It sounds amazing. Its ended up being quite heavy so I don't know if that makes a difference but it has sustain for days. Because of it being only a single pickup I bought a good quality Lolar pickup, CTS pots and an Orange Drop cap, and used vintage 50's wiring.
As per Lolar recommendations the Pickup is set quite close to the strings and with volume and tone on full it has a good bight, roll off the tone and it can be smokey smooth. But roll it off too much and it just turns into mud.
