I have a red knob twin. Thinking of wiring two ten inch speakers (4 ohms ea.) as an extension cab. How should I wire these speakers and which ohm setting should I use on the amp? Thanks, jim

Jim,

I used to have an Evil twin red knob. In a flight case. It fitted into the car but was a four man lift. Now the car’s suspension has gone. Along with my back. So I now have the red knob Super 60 valve amp. 1×12 half the watts just as loud and clean. But 2/3 the weight and same quality build and sound. Perfect. I would recommend the Super 60 if you value your bones.

Jase North,

Hi, all. I have a Red Knob that I love. It’s very versatile, very loud, and VERY heavy! I’ve had it for many years and it’s served me well but it’s time to down-size if anyone is interested. Located in central Texas.

Michael,
