Jono Bolton Posted October 29, 2018 Share Posted October 29, 2018 I finally got round to adjusting the action on my P Bass on Friday, and have managed to get the action reasonably low (2-3mm at the 12th fret), however the G string could stand to be a little lower still but the saddle is currently sitting on the bridge plate. The neck is straight with a little relief. Is a shim the only way to get the action lower than it is at the moment? Quote Link to comment Share on other sites More sharing options...
Manton Customs Posted October 29, 2018 Share Posted October 29, 2018 It’s not the only fix, but it’s the easiest. Other fixes would be milling an angle in the pocket or neck heel, recessing the bridge. Or a different (lower) bridge/saddles. So a shim is probably your best bet. Veneer works well for this. Ideally the saddles shouldn’t bottom out until the string are resting on the fret tops (just so you know what to aim for) 4 Quote Link to comment Share on other sites More sharing options...
Twincam Posted October 29, 2018 Share Posted October 29, 2018 I will add to the above good advice that a shim should be as thin as possible you don't need to make the neck angle huge, just enough to get the action you need. Experiment with folded paper you be surprised how thin a shim often needs to be. Then if you wish you can make the shim out of a different material to the size required. 2 Quote Link to comment Share on other sites More sharing options...
mybass Posted October 29, 2018 Share Posted October 29, 2018 Ah, the old days of putting a flat lollipop stick under the neck end to get the angle! Quote Link to comment Share on other sites More sharing options...
NancyJohnson Posted October 29, 2018 Share Posted October 29, 2018 I've had to shim a couple of necks in the past. It is amazing how a tiny sliver of veneer or sandpaper can have such an effect on overall playability. 2 Quote Link to comment Share on other sites More sharing options...
Jono Bolton Posted October 30, 2018 Author Share Posted October 30, 2018 Thanks. I've shimmed before but I've never really fully understood when a shim is necessary; I think in my youth I did it because I'd heard of other people doing it. It's far from being unplayable at the moment but I'll maybe give it a go over the weekend. Quote Link to comment Share on other sites More sharing options...

I've used stiff business cards in the past but I've got one in a drawer at work that's made of quite thin, recycled brown card, so that's going to be my primary candidate. 1 Quote Link to comment Share on other sites More sharing options...
KiOgon Posted October 30, 2018 Share Posted October 30, 2018 Have you checked it hasn't got a shim already? Maybe in the wrong place or just simply needs removing altogether. Quote Link to comment Share on other sites More sharing options...

Bigguy2017 Posted October 30, 2018 Share Posted October 30, 2018 The StewMac shims are excellent, albeit pricey as delivered from the US. https://www.stewmac.com/Materials_and_Supplies/Bodies_and_Necks_and_Wood/Electric_Bass_Bodies_and_Necks_and_Wood/Bass_Necks/StewMac_Neck_Shims_for_Bass.html The 0.25 degree shim was perfect for my Stingray whose original factory shim had embossed itself flush into the neck pocket over 30 plus years...

discreet Posted October 30, 2018 Share Posted October 30, 2018 (edited) I use a 1cm strip off a playing card cut to heel shape - doesn't seem to compress like other card or paper, works very well. If I want to raise the whole neck I'll use a whole card in there - usually a Joker, or the Ace of Spades - for mojo and coolness. Yes, I know.

Irrespective of the bass and it's provenance, why anyone would pay $10 for something that you can make for free out of a playing card or a bit of sandpaper is beyond me. I have some bottles of snake oil in my garage if you need to buy any. 1 Quote Link to comment Share on other sites More sharing options...

Muppet Posted October 30, 2018 Share Posted October 30, 2018 I cut shims out of the very thin plastic used in document wallets and ring binder covers as it tends not to compress over time. 2 Quote Link to comment Share on other sites More sharing options...

You really don't need a wedge. A thin strip of material will do the job across the neck pocket at the heel end. There is of course a huge thread on TalkBass about the merits or otherwise of leaving a (God forbid) GAP under the pocket end of the neck, but in my experience it really makes no difference to tone or sustain. Assuming you had any tone or sustain in the first place. Need a more extreme angle? Stick another bit of playing card in there. It works. There are those who claim to be able to tell if a neck is shimmed, what it's shimmed with and if there's a (gasp) GAP under the heel end, but I put those people in a box along with those new-age types who claim to be able to tell the difference between different types (and prices) of mains cables by the SOUND, can tell how much an effects pedal battery is DRAINED (sounds different!) or can tell how OLD pickups are by the perceived level of MAGNESTISM they have - or don't have. It's all a great big steaming pile of DUNG. 2 2 Quote Link to comment Share on other sites More sharing options...

I would guarantee to you that if I removed the shims you probably paid good money for and replaced them with an old business card or something cut out of a cornflake box, you would be none the wiser. Wedges? Pffft. If you believe that filling a tiny triangular void under the neck heel is somehow going to affect playability or tone or whatever drove you to buy a set, then you've been duped.

Oh, and thanks for the sneering and patronising comment. Naturally, you know me so well that you’ll know exactly when I’ll be none the wiser. As it happens they were given to be by a well respected repairer for free. So yeah - duped. I miss the good old days when people could be civil and polite and pay a little respect to each other. 2 Quote Link to comment Share on other sites More sharing options...
FinnDave Posted October 30, 2018 Share Posted October 30, 2018 Should you use a red or a black suite playing card to shim a bass with a through neck? Enquiring on a behalf of an acquaintance. 1 Quote Link to comment Share on other sites More sharing options...
