Do any of you have any experience with the Peavey Cirrus 6 and the Yamaha JP2? I'm wondering ow the low end compares?
I don't have experience with the Yamaha, unfortunately but I will say the Cirrus low end is quite impressive. Very tight and responsive low B that is crisp, clean and transparent. You'd be hard pressed to find a notably better sounding low B within the Cirrus price range.
