    Hello!

    I've got a quick question. I just bought a GFS Vintage '59 neck humbucker with 4 wires.

    Is it possible to wire it so that the middle position is single coil?

    I have an Ibanez AK95
    2 humbuckers
    2 volumes
    2 tones
    3 way pickup selector

    If that is not possible, what other tonal options can I do to the neck humbucker?

    the question is, do U really want to? I guess if you never use the bridge and neck pickup together, then why not. Most people go with push pulls on archtops, while with solid bodies it seems lots of people use mini toggles. I prefer mini toggles myself. I am pretty sure you could but you'll have to find a wiring diagram for it

    What I'd like to do is to have the neck as a single coil in the middle position so I can out some floating pickup-like sounds to try to emulate early swing chomping. Is that possible without any extra knobs?

    It's not possible because the 3 way pickup selector toggle uses the exact same hot lead from the neck pickup for the "neck only" AND for the "neck + bridge" settings. The selector switch only has two connection posts.

    Oh yeah. Thanks for the info. I guess I'll just have to wire it normally for now. Thanks again

    I have a really old electric that I removed the bridge pickup (in an amateur way) and now the middle position uses only the half of the neck humbucker and the sound is like the single coil but without the hum. I don't know if you want to go that way...

    I can highly recommend the Seymour Duncan Triple Shot pickup mounts including a coil split switching system:

    Triple Shot Switching Mounting Ring - Seymour Duncan Triple Shot Mounting Ring

    I fitted them to my Godin Flat Five with zero problems - no need to do any drilling or lots of re-wiring as all the soldering is done at the pickup mount. You can then switch between either of the coils in each HB or have them in series or parallel. Each of these options can then be combined with your three way switch in the normal way (24 different options).

    does this work? the flat five and the montreal have low profile pickup rings I thought. I've owned both. I would love to see this install. Any chance you could post a few pics? I'd really appreciate it

    Here's a couple of pics.

    The pickups are no longer the standard Godin issue, but I don't think I would have had any trouble with the Godins. The Triple Shots don't cause me any problem getting the pickup height correct - you can see that beneath the strings they are very low profile, but with a slightly higher profile where the 2 switches sit.

    You should be aware that the Triple Shots are available in more than one top profile. The Flat Five has virtually a flat top (as the name implies ?), but you can also get the Triple Shots with an arch to them, whether this is sufficent for the contours of your Ibanez, I'm not sure, - but there are dimensions on the SD web-site.

    This guitar also has a 5 way switch which in addition to the normal neck, neck + bridge and bridge settings allows me to pair the two pickups out of phase and in-parallel. The out of phase sound is very distinctive for certain types of blues. In all there are a total of 81 pickup combinations - 75 of which sound identical to me !

    Did I forget to say I also fitted a piezo bridge ? This example pre-dates the Flat Five X that has one factory installed, but the current Schaller piezo T-o-M model is a drop in replacement.

    I have the montreal. so what you have should be the same. I would be interested in swapping out the 5 pos. toggle for a 3 so I can split the pickups together instead of only one pickup at a time. Drives me nuts! I had a flat five but after I played it for a few hrs decided it was too muddy. I see u swapped your pickups as well, same muddy quality? How is the piezo replacement compared to a stock flat 5 piezo bridge?

    I saw a circuit diagram once that showed how to control a coil split with a potentiometer, not a push-pull. I may be wrong about the details, but I seem to recall it sending one of the coils through the potentiometer, so the pot acts as a volume knob for just that coil. Interestingly, you can get the sounds in between all-the-way-off and all-the-way-on. It was in Dan Erlewine's book.

    The Triple Shots will do the job you want to do on the Montreal - they are also available in cream.

    The replacement pickups I chose were a SD Jazz (neck) and JB (bridge). The immediate difference was the improvement in clarity and articulation - less muddy - which is what I was aiming to achieve, although I do now wonder whether that has been at the expense of som elass of warmth.

    On replacing the bridge, I was concerned that there may have been a loss of tone through the humbuckers. If you listen hard enough, you start to imagine anything under these circumstances. I think having lived with the new bridge for some time, any apprent difference in tone was my imagination. However, I admit I haven't yet nailed a great acoustic tone with the piezo pickup. This may be as much to do with the outboard pre-amp I am using as withthe pickup itself. Having said that, the design of piezo bridges is pretty crude. My occupation is concerned with the design of new industrial piezoelectric materials and devices; how the piezos are used in T-O-M bridges leavesa lot to be desired !

    Vintage use this approach on some of their models - particularly the semi-acoustics.

    I find that through a PA or an accoustic amp you can get quite close. Even running it thru my gibson amp almost does the trick. I have 2 acoustics with Under Saddle pickups, in comparison the Montreal really isnt that far off from them. That seemingly is just me though. I think MOST will side with you on the acoustic tonal quality of the piezo.

    The best piezo-implementation I have come across is in my Yamaha NTX700 - OK this is an acoustic so soemwhat easier to work with - they have made a real effort to tailor the frequency response of the transducers.

    well I figure when I get rich and famous Godin will make me a signature Montreal with Toggles for coil splits and the acoustic set up you get on the multiac jazz with a more resonant chambered body. haha.

    I love yamaha products. They make some of the best guitars I've heard. A guy I used to work with had a Super Axe ?500? I think it was, we did a side by side comparison to a Gibson 335 and it beat the pants off it. He got it used for $500 while the 335 which I think was 3000-5000 or something new. Biggest regret I ever had was not picking up an AE18 jazzbox a few yrs ago.

    I play a 1969 yamaha FG-180 that I restored. I love it

    I keep telling myself I definitely do not need a Montreal - but this thread has started my GAS again. Not good, especially as I have just bought a 5th Ave.
