I have a Marshall Origin 50c. I was wondering where the sweetspot is for this amp. I have my gain on 6, my bass on 2 my mids on 3 and my treble on 4, tilt is on 6 , presence is on 7 and master is on 2. I use it mostly for clean tone, then use my distortion pedal for the distortion that I need. I am a at home guitar hobbiest, and would like to know where the sweetspot is for this amp.
