Genesis: Blue (2)

Since I bought it in February, I've only managed to give my Ibanez RG550DX some TLC & due attention recently. The main consideration was getting the electronics done before tinkering with everything else. That means waiting for Mr. Beez to resume business after the CB period ended & it took longer than expected. The intonation for this guitar was off for most of the strings (4 out of 6 to be precise). The most horrible was the low E & from the physical evidence seen above, someone in the store was aware of this & pushed the saddle way back to address the issue. It looked wrong thereafter. If you have to push it way back, that's where the other (front) hole is for.

The front hole was utilized this time leaving the rear vacant & the issue was solved. 

Compare these front screws to the rear counterparts, these are obviously oxidixed. It happened when the instrument was not wiped down after play, leaving sweat to act on those metal parts.

These were removed, sanded & re-sprayed black. To make it a consistent affair, all four screws were given this treatment instead of only the two affected ones. 

Finally, the joke of it all; look at the orientation of the rear cavity cover. The slots are there to facilitate  tension spring adjustments. Even if your screw driver is the long version, it won't reach the adjustment screws as the inclination there requires some clearance.

This is the correct way. The slots give you immediate access to the adjustment screws. You can even see them to begin with.

Please bear in mind that this guitar was in showroom condition when I purchased it. It's not an out-of-the box unit in pristine condition. We can understand that all these anomalies were present in an attempt to re-string the instrument, making it more presentable (at least) before the sale event took place (it's what I wager, you need not agree). However, due to unfamiliarity with the features & mechanics, tuning & subsequent intonation issues manifested. I am glad that I could attend to these setbacks without breaking out too much sweat. If it's sent to a tech, it might entail some costs which might defeat the instrument's sale price to begin with.
