In short, yup!
B|Amp does indeed give you access to a huge amount of functionality. The DSP speaker profiles just don't appear on any other bass amp I am aware of. Absolutely brilliant. You can think of Forte as being a B|Amp as the signal path integrity is the same, however, think of the Forte as having a B|Amp with it's settings "locked" to an optimal configuration. The EQ is fixed, not fully parametric as an example. Yes, you can save programs on B|Amp and there is also a wireless foot controller for changing your programs (which may of course include a driven patch and then maybe a compressed sound, or EQ adjustments!!)
Do I think B|Amp is worth the extra dollar? If you saw the amount of kit I used to grab around in order to achieve what B|Amp can, the answer is a resounding yes. That said, Forte offers up a very strong argument for remaining on my shopping list.
