Do any of you guys with experience in running the AX8 into a FX Return of their tube amp have a modeled amp recommendation? This would be an AX8 pre-amping a Marshal DSL40 with a Creamback. I will eventually try the 4CM method but I figure I need to find a pre-amp tone or two from the AX8. I'm thinking that I should look for amps that are Pre-Amp distortion based amps, like a JCM800, Soldano, EVH, JVM,then turn the cab, pwr amp sim and sag off. Wouldn't the JMP-1 be ideal since that was a pre-amp unit? Is this the correct line of thinking?
