Floods amp settings — Roland JC-120 Jazz Chorus

The Pantera guitar tone for “Floods”, dialed in for a Roland JC-120 Jazz Chorus with a Jackson JS22 Dinky. Studio version, The Great Southern Trendkill (1996) — specifically the melodic outro solo section

Original rig

Randall RG-100ES solid-state head, Washburn Dime 333 with Bill Lawrence L-500XL (bridge) / Seymour Duncan '59 (neck), Korg ToneWorks AX30G for chorus/delay, plate reverb

Scooped high-gain with lush stereo chorus, long delay trails, and reverb wash — melodic and haunting rather than aggressive

Signal chain

01High-Gain Distortion (e.g., Boss MT-2 Metal Zone or MXR M116 Fullbore Metal)

RECOMMENDED — not currently owned. The JC-120 has zero distortion capability; a high-gain pedal is mandatory to achieve this tone. The MT-2's parametric mid-scoop matches Dime's V-curve EQ.

Gain/Dist 8 · Bass/Low 7 · Mid 2 · Treble/High 7 · Level 6

02Roland JC-120 Built-in Chorus

Use the amp's stereo chorus — this is actually period-correct, as the JC-120's chorus is legendary and Dime used similar modulation. Engage for the outro solo.

Speed 4 · Depth 6

03Delay (e.g., Boss DD-3 or DD-7)

RECOMMENDED — not currently owned. Set delay time around 450-500ms. Mode 0 = standard delay. Essential for the spacious outro feel.

Why these settings

The JC-120 is a pristine clean platform with zero preamp distortion—you cannot achieve Dime's gain without a high-gain pedal. Amp EQ set relatively flat with slight mid-scoop because the distortion pedal handles the V-curve voicing. The JC-120's legendary built-in stereo chorus is actually a bonus here; Dime used chorus on this solo and the JC chorus is studio-quality. Roll guitar volume to 8 and tone to 7 for the smoother, vocal neck-pickup lead tone.

PRO TIPDimebag doubled the opening arpeggiated melody and used finger vibrato (not whammy bar) for the slow sustained notes—focus on wide, controlled finger vibrato from the wrist, not the fingers, to get that singing sustain on the long notes.
