I have the poplar burl 5 string version of this bass and it is excellent. These basses are incredible for the price especially if you can get one used. The B string is nice and not too loose or uncomfortable. The finish on these basses is very thin and they can quickly be worn down to show the unfinished wood under. I don't mind a little belt buckle rash as I plan on keeping this bass for a good while so it depends on your tastes. This is the type of bass I think could benefit from a pickup swap. While the bass is very ergonomic (lightweight, fast neck, slim body) it also can be very bright when the treble is left at 12 o clock so I recommend lowering the treble substantially. The problem is that if you're not careful with your EQ you could end up making the bass sound too muddy and the notes will be indistinct. Some cheaper models of SR basses have been known to have bridge issues where the bridge will not hold strings correctly. I have not noticed this problem in my bass though I did have that problem with an SR305. The toggle switch is a mid frequency switch that changes the mids from 250 hz to 600hz I believe. Overall a fantastic bass that I have used for hard rock/ alt. metal and church as well. If you want a lightweight bass that gives a deep warm or bright snappy sound, this is your bass for basically any style of music.
Edit: Since first writing this review I have noticed that the bridge is starting to develop the bending problem I wrote about in my original review. This is apparently a common problem in Ibanez SR basses and sort of a "hidden cost" in owning one. Try to contact Ibanez about it or if you have a warranty you should be fine. I contacted Ibanez and they actually sent me a new bridge for free, I wasnt even the original owner. The replacement bridges should be sturdier. That being said, these basses are so fantastic in terms of playability and feel that despite having had this bridge problem twice, I would still buy another SR in the future.
