Cheers BassBus,
I will give it a go tomorrow, have band tonight and have put the old strings back on and its fine again. Do i turn until it plays ok and then leave it 24hrs to settle or do i need to turn, leave it 24hrs and then see if it plays OK. Sorry for all the questions, have always seen truss rod adjustment as a bit voodoo and don't want to f it up.
Kind Regards
Rob

Some people like to set a bass up by look and feel. I like to work with measurements to rough it in and then see how it feels.
If you can get hold of a capo, clamp that on at the first fret then hold the E string down at 17th fret. Then check the distance between fret and string at 5th and/or 7th fret. I use a feeler gauge of 0.3mm as a guide. if it slips in without moving the string the neck relief is OK. If it moves the string then trus rod needs loosening a bit more. If the gauge has room either side of it the trus rod needs tightening. Some players prefer a narrower gap. That's where feel comes in. It's what suits you and what you feel comfortable with.
Gary Willis' guide is good but remember he plays with a really light touch. If you like to dig in more neck relief might be better. Lots of vidoes on YouTube on the subject.
