    So I have a squier affinity and the saddles are dropped but the action isn't low enough for my taste. I have a small shim in already and more of a shim will give too much of an angle for my liking. Does anyone have experience with using flat shims that fit in the entire neck pocket and act as a "riser"? If so, how did you go about this?

    Hi.

    I always use a full shim unless the customer doesn't like that, so I'd just make the front lip a bit thicker, not a knife edge.

    Do install threaded inserts or longer neck screws if You raise the neck in the pocket, otherwise you may strip the threads.

    Regards
    Sam

    You could turn the truss to straighten the neck.

    Cut a piece of cardboard to fit in the neck pocket. Then get a thin piece of hardwood and cut it using the cardboard as template.

    I fitted an SX neck to a 1990 P Squire body and had to take a grinder to the bottom of the saddles to get the action I liked.

    I agree about a flat shim. I usually make them from thin solid basswood or birch ply both from the hobby shop and use the heel of the neck as a template.

    Well, if the tilt appears unnatural with an end-of-pocket shim, a full-pocket is the way to go. A trial 'n error paper template is your best bet. I have cast-off hardwood veneer samples that work nicely and can be shaped with a common xacto razor.

    I'll assume your saddles are bottomed-out. How much of a "boost" does the neck pocket require? Remember to check and re-set your witness points if you've not already done so...the practice is largely ignored and creates all sorts of problems. It may also drop the strings closer to the "deck" (fingerboard) which, in your case, would be desirable. Mod'ing bridge saddles is also an alternative unless it results in a too-shallow break angle.

    I've never done it, but I've read that business cards work well for this too.

    Instead of a freaking shim?

    What's with some people?

    LOL... worked like a charm and it's a friggin squire for goodness sakes and now its a well playing squire. I've never been a fan of adding a shim between a neck and a body. Always seemed like a weak joint. I have done it... just don't like it.

    I shimmed my Lakland 55-60 neck last night with a business card and it worked like a charm.

    That sounds (potentially) like a really good idea !

    I like it.

    I don't know about a Lakland, but for a Squier the "traditional" shim is a machbook cover from a dive bar... :)

    Now that you mention it, I've noticed that since smoking has been banned in bars here, the bars don't seem to have those cool matchbooks anymore.

    The finer boutique builders will use a section of the dorsal of the Australian Baramundi for shimming.

    Personally, I always thought there was something fishy about that. Though it may help when playing scales. I tried it - got me hooked.
