maybe someone can give me some input?i am basically a tone idiot...but i am slowly starting to figure things out.i have a mark 4 a.i think i have finally discovered the tone i am looking for(especially my big struggle,channel 2)wanting a nice crisp clean channel...an ac/dc like punchy channel 2...and a meaty lead channel,what i have done is use the 6l6 el34 combo on simulclass....pentode for some extra punchyness...but recently i borrowed a boost and it made all the diff in the world for channel 2.could someone reccomend a resonably priced boost.the boost i borrowed was an ocd that is about $200.are the grande boosta pedals any good?also should i run on full power for even more drive?yes im an idiot...any input would be awesome.thanks guys.
