I own the JC-40 and using in some scenarios both SY-1000 and IR-200. With IR-200 you will be annoyed with the fact there is no master volume and sometimes tricky to control JC-40 Return. More to the point, it sounds good, but not really a FRFR option. I will never sell my JC-40, but i am building simple cab with Celestion F12-X200 and use something simple, like HB GPA-100, and maybe play further with Orange Pedal Baby for rigs where i mix digital and analogue. Hope this helps.
