No more tears amp settings — Positive Grid Spark go

The Ozzy Osbourne guitar tone for “No more tears”, dialed in for a Positive Grid Spark go with a Fender Telecaster American professional. Studio version, No More Tears album (1991) — iconic main riff distortion

Original rig

1981 Gibson Les Paul Custom with EMG 81/85 active pickups → Boss SD-1 Super Overdrive (Level 6.5, Tone 5, Drive 6.5) → Boss CH-1 Super Chorus (stereo to two heads) → Two Marshall JCM800 2203 100W heads (6550 tubes) with Preamp 10, Master 4, Bass 10, Mid 5, Treble 9, Presence 3 → Marshall 1960B 4x12 cabs with Celestion G12T-75s. Tuned down to C# standard.

Massive, thick, bone-crushing crunch with scooped mids, boosted bass and treble, tight low-end from EMG actives, always-on chorus for stereo width and body

Why these settings

Your Tele's single-coil bridge pickup is brighter and lower-output than Zakk's EMG 81 humbuckers, so bass is pushed to 9 (vs original 10) and treble pulled to 8 (vs original 9) to avoid ice-pick harshness. Gain set to 7 because the Spark's digital modeling saturates faster than a real JCM800 at 10. The compressor compensates for the passive pickup's looser attack compared to active EMGs. Mid stays scooped at 4 to nail that hollow-yet-heavy Zakk tone.

PRO TIPZakk used .060-.010 gauge strings tuned to C# — if you stay in standard tuning, palm-mute harder and pick closer to the bridge to get that tight, aggressive chunk. Roll your Tele's volume to 8 for the clean intro section, then slam it back to 10 for the riff.
