I ask this because I recently got a good JF30-12, and I find I tend to 'cheat' and revert to my F-2512 when things get difficult. I think that's 'cos the JF30-12 sound is just so big and sustaining that I need to develop the skills to control it better. The F-2512 is less demanding (it's also lighter with a slimmer neck, but that's a different issue). What do you think, have you found this when you upgraded? Thanks, Max
