There are two reasons for this. First, thebuild quality and reliability is unmatched. Second, the mysterious nature of them, partially due to thefact that the circuit is obscured and partially because of the A-list of clients such as Brian May and PeteTownshend.The SS-3 in particular is owned by Jeff Beck, David Gilmour, Keith Urban and Carlos Santana amongmany others. It’s an update to the earlier SS-2 that adds a low-cut control, since the original was fairlybass-heavy. With the low cut control set fully clockwise, the circuit is identical to the SS-2.Under the hood, the SS-3 appears to have originated from the MXR Distortion+ circuit and then hadpassive low & hi-cut tone controls added, along with the classic Cornish buffer at the input.The Soma is a faithful reproduction of the SS-3 circuit, but with one major addition: an internal slideswitch allowing the pedal to be used in true-bypass mode instead of buffered bypass. As with the KlonKTR, the buffered mode is “almost always better”, but with this feature, you can determine for yourself.USAGEThe Soma has the following controls:• Sustain controls the amount of drive or distortion, which also affects the amount of sustain.• Low Cut is a two-stage filter that cuts bass at 60 Hz when counter-clockwise. When this control isfully clockwise, the low-end response is identical to the SS-2.• Hi Cut is a basic passive treble control, starting with a steep 6KHz cut at minimum, and a slightboost when fully clockwise.• Volume is the overall output.
