Stephen O'Malley

Stephen O'Malley of SUNN O))) is known for utilizing the Orange Amplifiers AD200B 200W Tube Bass Amp Head to achieve the band's signature low frequencies and warm tones. This user-uploaded photo on Flickr captures O'Malley with the amp, reflecting its consistent presence in the band's setup since the early '90s.

In the guitar.com's interview with Stephen O'Malley, a list of O'Malley's guitar rig was published. One of the items included on the list was Sunn 2000S.

I used a Deluxe Reverb as well. That was different for us. There are also times when we’ve played with just the two of us live. We’ve incorporated a Fender Twin with each setup, so you have an extra push over the cliff.

"We did a few duo shows last year, and in one of those shows, we had an extended backline that involved four full stacks each, three Ampeg stacks each, a half stack, a Sunn half stack with a vintage Sunn cabinet, a 50-watt vintage Sunn – like a Sonaro and Solarus – and a Fender Twin on the very outside wings.
