Hey, everybody. Brand new to the site, and I'll be damned if can actually be of some help. I have a Takamine EG-240RS with the same problem. Now, I'm no luthier. But, I've got great mechanical aptitude, and a basic understanding of the physics involved. So, I've been round and round with most of the local guitar stores over this thing, because I'm determined to put something in that slot that will last longer. It's a "good news-bad news" situation. The good news is that there is a workaround to this problem, but it's only temporary. The bad news is that Graph Tech doesn't make a micro-balanced saddle that is 3 inches long.. But, whatever.
First, the workaround: Someone in this topic previously discussed shaving the top of the saddle, and this is really the key. BUT FAIR WARNING: There are multiple angles that must stay consistent, and of course, they are not straight bevels. You must also keep the curve in the top of the saddle to maintain string geometry. If you do this yourself, be prepared to spend hours. I recommend taking pictures before you start, and working very slowly so you don't overdo it. HERE'S THE WORKAROUND. The saddle sits inside a metal tray, which contains the piezo pickup (hence the reason for not shaving the bottom). Underneath that is a thin metallic grounding strip which sits loosely in the slot and acts like shielding tape to reduce feedback. As long as you make sure that this strip stays directly underneath the pickup, you can place a shim underneath to compensate for the height taken off the saddle.
Should all else fail, I found and eBay link out of the UK of all places, where they sell hand made copies of these saddles. I've never done any business with them, so be aware that you do so at your own risk. But, here's the link: http://www.ebay.ie/i...#ht_1705wt_1272
