are there any precautions which need to be taken when using a fender deville 4x10 with a 4x12 marshall cab (1960a)? i just got a new deville and had it run to the marshall earlier today. i was a/b testing the difference between the tone (same settings) out of the fender speakers and out of the marshall. it seemed considerably different, especially when using the clean channel. the clean channel through the marshall sounded like a lower gain setting on the dirty channel, whereas it sounded all the way clean through the fender speakers. the amp also got very very hot (to the point of a little smoking) when using the marshall cab at high output levels from the fender deville. anyone care to offer their two cents?
