Sweet Child o' Mine by Guns N' Roses — Amp Settings & Guitar Tone

Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.

To recreate Slash's iconic tone from 'Sweet Child o' Mine', we'll use the Squier Classic Vibe Stratocaster '60s and the Fender Mustang LT25. The Strat's single-coil pickups will substitute for the Les Paul's humbuckers, while the Mustang's modeling capabilities will approximate the Marshall JCM crunch. We'll focus on achieving a bright, mid-forward tone with smooth sustain, using the amp's built-in effects for delay and reverb.

What Guns N' Roses actually used

The recording of 'Sweet Child o' Mine' featured Slash's 1959 Gibson Les Paul replica built by Kris Derrig, played through a Marshall JCM 2555 Silver Jubilee amplifier. The guitar tone was shaped using a combination of pedals, including a Dunlop Cry Baby Wah set in a fixed position, a Boss GE-7 Graphic Equalizer for midrange boost, and a Boss DD-3 Digital Delay for slapback effect. In the studio, two Roland SRV-2000 Digital Reverb units were employed to enhance the guitar's distinctive sound. The track was produced by Mike Clink and recorded at Rumbo Recorders in Canoga Park, CA.
