My favorite speaker combo (this month ) is the Celestion G12H30 and the Vintage 30 together in a 2X12 cab (I actually have a G12H30 and a WGS Veteran 30).
Tight bottom; warm, punchy mids; smooth highs. Funny, but to me the highs with the Vintage 30 alone sound a little harsh or shrill. I don't hear that with the WGS Veteran 30, and in combination with the Celestion G12H30 it's really balanced.
That is a great video demo. Only place I've ever heard each speaker in rapid succession with the exact same riff played over and over. Good stuff!
Ah, nothing relieves the discomfort of GAS pains like the sound of the UPS truck rumbling down your street. It's like the musician's Beano.
