What's the difference between the Ibanaz SR300E and SR300EB ?

[Davyo]

My apologies for the dumb question but I'm new to getting an Ibanaz brand bass, 4 banger.
Is the difference between the the SR300E and the SR300EB just the available color's ?

And another question if anyone knows this answer, I'm an avid longtime BEAD tuned bassist, does anyone know what the largest string gauge the factory cut nut will accept ?
I use many different gauges for my low B, from 120 to 135, just wondering if I would still need to modify the factory nut if I used a 120 low B ?

Thanks much in advance.
Cheers
Davyo

The colors and the color of the hardware are the only things different I see.

"B" for "b"lack hardware?

Yeah, they have the same thing with the Mikros.
The one I like was a B model that came in a Walnut finish with black hardware:

I would bet money you'll need to file the nut slot to put a 0.120" string in there.
