I'd like to come but can't make the January date. I'm free on the 23rd Feb though.

Okay, i'll order the parts and give it a go. I will report back presently. G

Guys, I think that a pull up vol pot and a blend pot should do it. I will take measurements of the existing pots and holes and try to match up with the offerings from Maplin etc. With this config, which wiring diagram should I use? I am hugely grateful to you for spending your time helping me with this. I really love the Jack and enjoy playing it. Graham

I had a look inside and they are 500k pots. Does that mean that I should buy 500k resistors to match? I have followed your link to Maplins for the resistors and if I am looking at the correct product, they are called Cermet preset potentiometers and do not have 250k, let alone 500k values. Am I on the wrong page? Also, if I go the push/push S1 route, will I have to use a Fender knob? If so, to keep the bass looking authentic, I would prefer to use a pull up vol pot and the original knob.

I went with the G30 and am delighted with it. I use a ComfortStrapp and the sender unit sits very snugly in one of the elasticated sections sewn to the neoprene pad. I made up a dedicated length patch lead and zip-tied it to the Strapp fittings to keep it all neat and tidy. The advantage of tucking it into the elastic is that there is no way that the battery compartment lid can work its way open, and the jack into the sender unit is pretty much fixed into position too so it can't move around and wear the components, which I have heard on the grape vine are the two main faults with the G30. I could post pics if anyone is interested.

Thanks, Brensabre79, that is [u]exactly[/u] what I was looking for. Please post the diagram. Where did you source the pots? I have a Maplins nearby. I have yet to find the time to have a look at the pots regarding their k rating. Thanks for the help so far, guys.

Hi SparkBird, Thanks for looking at this for me - I had all but given up hope of sorting this out! I will have a look inside tomorrow and let you know. ATB, Graham

If you are based in or around Taunton, Tiverton, even Exeter area (South Somerset, North/Mid Devon), try calling Pete Searle - he is an electronics wizz who works from his home in Dunkeswell, near Honiton. He does work for Mansons of Exeter (excellent music shop). I have gone to him for repairs on amps and cabs and been very pleased with the service. He is a late sleeper so best to call him after 11.00am 01404892908

Bump..

Hi All, I have a mint condition original, unmodded Jack headless which has active J type EMG select pickups. I have seen on the forum posts about an upgrade which puts the pickups in series (thanks to geoffbyrne for his advice on this), but I would prefer to utilise the existing holes, not drill another one for a switch or use the red LED hole - I quite like the light . Whilst I am not a total space-cadet when it comes to electrics, I am a little lost with electronics so I would be very grateful if any if you who have knowledge in this area could help me. I know that there has to be a switch to select parallel or series which has been achieved by others using a push-pull, but is there one available which also incorporates the facility to blend the inputs from the pickups? Would it be possible to have one volume pot to serve both parallel and series modes and a blend-with-select switch? Maybe I could use a second concentric pot as is used for the treble/bass...? As you can see I am somewhat confused. This is the wiring diagram that I have cribbed from another Basschat post (thanks to Sean) :- [color=#282828][font=helvetica, arial, sans-serif][/font][/color] [color=#282828][font=helvetica, arial, sans-serif]All help gratefully received.[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Ta,[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Graham[/font][/color]

Not wishing to hijack this thread, but seeing as octavers are under discussion, does anyone know of an octaver that reproduces an octive up? Thanks GrahamT (no relation to OP)
