This is your primary gain source — the Uzi is a high-gain pedal so keep gain moderate for Marshall-style crunch rather than modern metal saturation. Voice switch to 'Low' position if available for tighter response.

Why these settings

The Ibanez Promethean P20 is a bass combo amp — it lacks the mid-forward voicing and preamp saturation of a Marshall guitar amp. Keep the amp nearly clean (gain at 2) and let the Joyo Uzi provide all the distortion; the Promethean's job is just to amplify cleanly. Push mids to 7 to compensate for the bass amp's naturally scooped guitar response. Your AR300 humbuckers are hotter than Slash's Alnico IIs, so the Uzi's gain at 5 reaches his saturation level without mud.

PRO TIPPick directly over the bridge pickup pole pieces with a slight downward attack angle — this gives the intro arpeggio its bell-like chime and note separation. The riff lives in the pick attack, not the gain.
