Same pickups used for '64 Ventures & '67 Joe Maphis, others?

[tom-ocaster]

I haven't set-up a photobucket acct yet. So, I posted this '64 Mosrite on flea-bay for now. I posted some decent pics.

I am open to reasonable offers, or possible trade for a vintage guitar (Martin & Gibson flattops, Fender & Gibson electrics).

I am new to this forum, and not certain about the ethics of posting the link...so I won't.

When I figure-out the photobucket acct, I may list the Mosrite here in classifieds.

There can be a cold solder joint which restricts or breaks continuity for a strong flow through the wiring circuitry. Some times it can visually look like everything is fine but if you wiggle the wires at their connections usually at the tab of the pot or on the pickup itself, the cold solder joint will usually break loose. Or, the ground wire may not have be routed properly. The guitar may still play and the first thing people think is something is wrong with the pickup. If the coil wire of the pickup has been damaged or broken there won't be any sound. A pickup magnet can become weaker with age and not sound as strong or as good as it use to but since the pots have been changed that would make me think it was wired improperly or has a bad grounding joint.

Thanks Danny! I have to check my Maphis bridge pup regarding this issue.

A pickup with a break in the winding will still make sound through an amp. It will be usually be weak and thin sounding, but it does make sound. If you try reading the resistance it will test as an open circuit.

The reason is capacitance. The coil wires are so close to each other there is a capacitance created by the proximity of the windings.

Oops! I stand corrected! I've never experienced that as the pickup was always dead with no sound with the 15 plus ones that I re-wound with a broken coil wire. Think I'd better go back in to retirement.

Part of it will depend on where in the coil the break occurs. If it happens at the very end of the coil where the hot lead is connected it will have less out put than one that breaks in the middle or at the end of the coil that is grounded.

The most famous case of this is the neck pickup on EVH's original Franken-Strat.

I suspect that this open circuit is what is going on with the '64 pickups. I think that the rust on the pu polepieces is likely a contributing factor to the open circuit.

At first, I also thought that the wiring & pots were wrong b/c of the replacement pots (250K, not 500K). But, after unsuccessfully obtaining a valid reading on the pickups, my suspicions leaned toward the actual pickups.

The deal I mentioned earlier with the '67 pickups is no longer available. I will likely either have the current pickups repaired/rewound, or buy a set of Ed Elliott's pickups.

Thanks for your input.

I have listed this guitar in the Classified section here at the Mosrite Forum. $2650, 48 Hour Approval, Free S/H.

Also, does anyone know if the pickups made for the mid-'60s original Ventures Models are the same pickups as used on Combos, Gospel, Celebrity models, Joe Maphis, etc??? I am still interested in acquiring a set of original pickups that would be appropriate for this Ventures Model.

The '65 Ventures Model I have has pickups with an output of app 12K.

Thanks again!
