I have an old Fender Jazz Bass with a serial number from 1978. It needed a bit of setting up and I googled the ‘micro-neck adjust’ feature mentioned on the neck base plate and couldn’t find any information. So I thought I’d share what I found here so other people can find it more quickly.
The truss rod adjustment requires an 1/8″ allen key, the micro-neck adjustment is 3/32″. It was very stiff but some gentle leverage worked and I found that turning clockwise set the neck backwards and vice versa. By tweaking the neck angle first, then the truss rod and finally the bridge saddles I was able to get a much nicer action and overall playability. (Saddle height requires a small flat screwdriver, intonating requires a larger cross / philips head screwdriver).
I’ve had four or five people friends ask me to repair their Line 6 DL4 delay / loop pedal now. The problem is always quite simple – the pedal simply won’t turn on at all! The repair is just as simple. (I dread to think how many of these might have been thrown away when they could have been so easily saved.)
Basically you just need to open the pedal up and reseat the EPROM chip (carefully prise it out, then put it back in again). It takes three minutes and requires no soldering, as shown in this handy video I’ve made for you. This was 100% successful with all the ‘bricked’ DL4s I’ve received, but obviously I take no responsibility if you damage yours further!
I repaired a few stompboxes for a friend and thought it worth writing down and linking to some of the replacement components, to hopefully speed up other people’s repairs as it took me hours to source the correct ones!
