Ibanez RGD7521PB-DSF

The good-
The clear stars here are the pickups. They provide a crushing tone, with very clear low ends and super neat lead tones. The coil split sounds great too, as it gives the guitar a nice glassy sound. Works on cleans too. The guitar is ergonomic and a feast to the eyes.
The bad-
If you are a fan of low string action, you might want to think again. It is simply not enough to just adjust the saddles, and you will struggle with the truss rod. After adjusting the action many times over, the strings still hover at about 2,5mm above the frets.
The ugly-
The condition I got the guitar in is not the best. A fair amount of small cuts, nicks and scrapes can be found around the edges and on the back, and even some gunk has been left on the guitar. None of this affects the tone or playability, but it's a shame to find a guitar in such a condition. The cuts are not visible from the front in my case, but the qc is definitively not good here.
Overall it is still a great guitar, both for riffing and shredding.

Once took it out from the box, I was amazed by its look. Guitar came in a perfect condition with no scratches or smth - it really felt like a solid, beautiful Ibanez.
I was planning to buy some guitar for Djent, Thall and some heavy distorted tones and didn't expect a lot from PAF 7 pickups, though they actually made me feel like they're worth keeping them.
Tuners are solid and precise - good enough to keep, but you might want to upgrade to locking tuners. I think that both options would be fine.
Gibraltar bridge is something I really love about Ibanez guitars - the look and feel are amazing. It's really comfortable for my playing style and my right hand is much happier than if I'd play some Fender guitar with screws that would cut it off.
Volume knob feels smooth and nice. Switches are solid and sound is crispy - just the way I love it.
I am not gonna talk a lot about Wizard II neck - I just love the profile and it's comfy as hell. Guitar also came with a low string action set up with no buzz, just the way I love it.
--------------
Conclusion:
It overall is a great guitar and is decent enough to play without feeling that something is off. Long scale and good pickups will give you an option to record some low stuff without worrying about anything else but your ideas and creativity.
9/10 (I wish it had black tusq nut and locking tuners, but everything else is great)

Let's start from the end.
This is a kickass guitar. Great value for money. Sounds great, especially in genres it was supposedly designed for. I don't have any second thoughts and would buy it again :)

Now, for some negative points.
1. My guitar has some finish problems - a streak of blue color from the top coat was transferred to the non-painted part of the body. I got a discount from Thomann because of that so no problem here.

2. It has EXTREMELY simple electronics so it works best on humbuckers on a full volume.
The guitar has no tone control and no tone shaping inside. It loses high end significantly when the volume knob is turned down. Also, there is a prevalent "spike" or a resonance in the sound spectrum when switched to single coils - nothing that some EQ wouldn't fix, but it's there.
It is therefore somewhat sonically limited and some electronics mod might be in order to remove this limitations.

BUT if you need a bone crushing metal machine that stays in tune perfectly, handles drop G# on 10-62s well and looks amazing - then it is perfect out of the box - you won't need anything else.
