High Gain Master Volume MkIII Vs SL-X Vs High Gain Dual Reverb. The guitar is a Gibson Les Paul Black Beauty R7. The MkIII and the Dual Reverb are 100W but the SL-X is 50W, why the two former are ran in "low" mode (50W) and the latter in "high" mode (50W), not exactly the same but good enough. Settings:
Tone stacks: Treble 50%, Bass 35%, Mid 100%, Prescence 5 (however the Dual Reverb had lower Prescence)
Gain: MkIII and SL-X: Preamp: 100%, Gain: 100% (40% for low gain licks), Dual Reverb: Lead Gain: 100% (50% for low gain licks)
Master Volume: 40% using a Weber MASS 100 Power attenuator set on 1.
Cheers!
