So just last weekend, i drove over to SweeLee and took a look at their showroom displays. Apparently, the shop assistant told me they had just finshed a recent SweeLee Sale and thus the explanation for the vacant spaces around the shop. I was so intrigued and glued to the IBANEZ guitars that were displayed there! As i was there to see and feel the overall exterior of the guitar, it's indeed true that the neck and structure of the guitars are really suitable for lead-playing. I found it pretty comfortable to play, although I didnt have the opportunity to test out the pickups and sounds yet. Well, take a look at the few pictures and maybe you could provide some advice and comments on the few which I took notice of?
* Ibanez JS100 Series Electric Guitars *
"I wanted a guitar with a modern sound, but with a vintage feel, with smaller frets and more radius on the fingerboard. It had to be subtle enough to catch nuances, fast and easy to play." - Joe Satriani @Ibanez.com
The JS100 is designed to Joe Satriani's exacting specifications, with his custom neck profile, 2 custom designed humbucking pickups, and the Edge Pro II locking tremolo. The body is thinner than a stock RG size body, but thicker than the S-Series, to provide a great combination of comfort and tone.

This was what I initially set out to buy, for the fact that although this model is pretty old,it's sold at around SGD$1100+(for a Signature Series)! Quite worth the buy, except that firstly, SweeLee doesnt have stock other than the black coloured one ( I wouldnt mind the red or white one), and that perhaps the pickups used cant beat some of the other models.
* Ibanez RG Prestige2570E *

Specs:
Wizard Prestige neck
5pc. Maple/ Walnut Neck Material
Basswood Body
24/Jumbo frets

Basswood is a comparatively lightweight wood, which makes it very comfortable for extended playing. With a good balance of highs and lows, basswood is right in between alder and mahogany in sound character. The 24 Jumbo frets offer easy playing for leads and chording.

This seems like a better buy overall, did some reading over some forums and people were saying that in comparison with the signature series, perhaps the RG Prestige is a much better,versatile buy for hard rock n stuff. Then again, the price for this is almost SGD$1800+... and with that price, i would rather pay bit more and probably get a Fender or Gibson manz. haha.
