Welcome Ksor.
Looking at the circuit of the Fender Blues Deluxe the Power Amp In appears to be quite sensitive, only about 35mV for full output, in fact this should be similar to the normal main inputs.
If you don't have a users manual for the Korg AX1000G then you can download it from www.korg.co.uk/downloads/ax1000g/AX1000G_OM.pdf. If you haven't, I suggest you download and read.
You could make up a simple 10:1 or 100:1 output attenuator lead with a couple of resistors in one of the plugs, but have you tried setting the Master Level to a low value?
I think I'll try the "lowering-master-method" in the first place
