01Morley Power Fuzz Wah (or EHX Bass Big Muff Pi)
RECOMMENDED — not owned. Cliff's lead tone requires external fuzz; engage Overdrive channel on the amp until you acquire one.
The GK 2001RB's dedicated Overdrive channel and G.I.V.E. boost stage deliver aggressive growl, but because Cliff's tone relied on a Morley Power Fuzz Wah driving Mesa tube heads, you must engage the GK's Overdrive channel with high gain to approximate that saturation. On the 2001RB's active 4-band EQ, push high-mid (7) and treble (7) to capture Cliff's bright 1.5kHz attack, keep low-mid at 6 for body, and leave Contour at 0 so you don't scoop the vital midrange. With the recommended fuzz pedal added later, switch the GK to the Clean channel and drop preamp gain to 3.
