RECOMMENDED — not currently owned. Essential for Fieldy's grinding midrange clank and DI grit. Run direct into amp input. Without this pedal, the Rumble alone cannot replicate the aggressive edge.

Why these settings

The Rumble 40 is voiced clean and modern with a natural mid-scoop, which actually suits Fieldy's scooped tone. Mids at 3 enhances the scoop; treble at 7 brings out the percussive click Fieldy is known for. Bass at 7 provides the low-end thump without mud. Fieldy's SansAmp adds essential grit and harmonic content that the Rumble's clean preamp cannot produce alone — the recommended pedal is critical for authenticity.

PRO TIPFieldy's signature clank comes from attacking the strings hard near the bridge with his fingers, letting them slap against the frets. Dig in aggressively and keep your fretting hand loose — the buzzing fret noise is intentional and defining for this tone.
