An old "trick" I learned in the 80"s, was to use a Boss 6 band graphic eq pedal to get a faux dobro sound.
I still use this idea on my pedal steel patches. I was going to use my dobro at a gig I played this summer, but
the stage volume was too loud and my dobro was feeding back, so I use my pedal steel instead.
So, in the amp block is a graphic eq. Set this to the 7 band eq of your choice.
Boost 200 and 3.2K 4db boost to taste
Boost 800 8db With my pedal steel, I boost this +10(not at my AxeFx currently, not sure of value ).
When I tried a dobro, it didn't need as much of a boost
Cut 100,400,1.6K, 6.4K- full cut
