Had reply from de lisle , l have somehow added an extra wire from volume pot to bass pentatone , hence the loss of volume smoothness (all effect at full turn) BUT , wired correctly as de lisle say , there is a large amount of volume lost as you go through the 6 positions , but the volume control works smoothly .
I'm going to leave it with the extra wire , as l prefer the smoother sound , and less volume loss going through the positions .
I will post both sketches later today , maybe someone with electrical knowledge can explain?
Looks like the Glock will take a back seat for the time being .
