The power amp was designed to stay clean to keepįrom distorting the signals from the preamp and FX Loop. Overdrive harmonics generated by harmonicĪnd intermodulation distortion from getting through unfiltered by the tone controls.

Late in the preamp after the primary distortion triodes to prevent Like the JCM800, the SLO amps place the tone stack The FX loop is placed after the primary preampĭistortion triodes-the Clean & OD Preamp 4 and the FX Buffer-so effects are not distorted by preamp Things clean for the FX loop, tone stack and power amp. On the cold clipper stage and large preamp grid stop resistors keeps highįrequencies in check and prevents ice pick and oscillation.īreakthrough amp is it generates almost all distortion in the preamp then keeps Gain stage beyond the Marshall JCM800 preamp without generating harsh square Ground! Dumping large portions of the guitar audio to ground soundsĬounterintuitive for a high gain amp but it allowed Mike to add an additional Soldano controlled inter-stage gain withĪttenuating voltage dividers that dump up to 96% of the guitar signal to Harsh sounding square wave over-overdrive and to moderate very low and The trick is to dump excess signal to prevent Mike Soldano was the first amp designer toĭiscover that great overdrive tone can be coaxed from a cascading chain of The Soldano Super Lead Overdrive SLO-100 was a breakthrough ultra-high How the Soldano Super Lead Overdrive SLO-100 & 50 Watt Amplifiers Work
