Just got a HD400. it's overwhelming. What is a good strategy for setting this thing up? I'm thinking just set a few core amp tones and going stomp mode? but the pre/post thing is confusing. I know it's pre or post amp, but the volume difference is crushing. my mindset would be all pre. Engineers want all post control. but i like to hear what's coming out of the amp. and can someone explain this row of master sag hum bias biasx? I get master, but bias? And the thing below it, DT class topology? ugh. i'm just a player, not a tech head. Funny, it also has all the noise that used to come outta the Marshalls.. wow Any input is greatly appreciated.
