Hi guys and girls. I have just "reinstated" an early 80's Westone bass...been in bits for years. it has a single humbucker, volume and tone, like a p bass - on connecting to an amp (any amp) the volume is quite low on the first fret on the E string, a bit louder on the second fret (same string) and gets progressively louder as you get towards the 6th fret, where it will stay at a constant volume all the way up the neck. the effect is less noticeable on the other strings but still there. any ideas as to what is going on? Cheers.
