The 1987x before the most recent firmwares was extremely harsh IMO. I couldn't get a good sound.
Last night I was just going through all the vintage plexi amp types and comparing and was shocked at the 1987x. especially when you consider it a regular production run marshall. I think I feel it to have far more character and attitude then the vintage plexi amps in the axe fx, and for pure classic rock sound, I may replace all my rock patches with this amp.
