try using the greenbox instead with the distortion all the way down and level way up. Keep the amp gain about 1/2 way. I think it sounds much better then with the mythic drive. YMMV.
I have an I like that sound for more 60's oriented slight breakup. But i mainly stick to one patch which is now the BB15 with greenbox.Try the '57 Bandmaster with the 4x12 B Greenback cab. It is awesome also!!!!
