What’s the difference between these two Ibanez Sr5005 models

[motorhead9999]

So when looking at an Ibanez SR5005, I noticed something odd, and I can’t understand if I’m just missing something. If I’m looking at the pictures correct, one of these models seems to have a an extra dial compared to the other.

if you look at this Sweetwater link, there are 3 dials along the outer edge

However, if you look at this link, there are 4.

On the Sweetwater one, it looks like the 4th dial is replaced with a toggle switch. Am I just going crazy here, or is there an actual difference?

The second one is an older model. Bridge saddles are different as well...

Ibanez also moved the truss cavity to the heel.

@Basehead @hypercarrots and @songwriter21

is there any advantage/disadvantages between the changes on the two models?

 

[Basehead]

EQ-wise, it's really personal preference.
I favor the newer preamp and I don't feel limited by the 3 mid frequency options. Also, I like the newer bridge saddles as they are adjustable (if that's your thing). AND, I do prefer the neck adjustment at the heel...

I think the current ones are way too dark sounding, but way easier to adjust the trussrod. I think the best sounding Prestige SGRs are the older 3000 series (3000, 3005, 3006).
