I have two cabs loaded with Scumbacks for my SLO
Soldano closed 2x12
H75 LDC_H55
Soldano open 2x12
M75 x 2
I prefer the first one because it has more high end and lows; broader tonal spectrum. LOVE IT. More versatile and better for searing leads and hair band -Lynch era metal.
M75 loaded cab is smoother and tames the high end, as you'd expect. A bit more classic rock sounding. But if your guitar is very bright it could be the ticket.
