I'm really GASing for a ENGL right now but if it would be for my personal use it would be the following:
Mesa Mark IV Long head
Mesa Rectifier Standard 4x12 Standard (Oversized)
This is just purely based on my preference but to this day i still love the Mark IV and it still is the amp i judge other amps against for high gain tones. I own a Mark IV long combo and i love it, especially when plugged into some V30s! I would love to have a head version. I initially wanted a head but the only Mark IV i could find at the time was this combo.
If your asking for something you can purchase today then i would go with the same setup but with a Mark V instead.
