Differences between different Laney RB9 heads

[Gonzo476]

I've seen three versions of this head:

1) Silver-faced
2) All black Invalid Link Removed
3) This one [Invalid or Expired Link Removed]

Does anyone know if there are any differences apart from the looks?

Ok, I e-mailed Laney and this is what they said:

''Hi Gonzalo,
On the new RB9 the internal electronics are quite different, the Amp is slightly smaller and has a mini jack aux in.''
