How it’s played

straight, medium tempo, soft dynamics · edge distortion. This shapes how hard the amp is pushed and where the EQ sits for the Under the Bridge sound.

Difficulty

4/5 · Riff

The riff requires advanced chord shapes, precise picking, and dynamic control to maintain clarity and articulation, making it challenging for intermediate players.

Worth knowing

No official studio amp knob settings found; values are averaged from multiple forum sources and typical Marshall Silver Jubilee settings for Frusciante's clean/edge-of-breakup tone.
Compressor pedal is widely reported and audible, but exact model for the studio session is not confirmed. MXR Dyna Comp is most likely based on era and Frusciante's known gear.
Chorus effect is debated; some sources mention Boss CE-1, but it is not clearly audible in the riff section and is omitted here.
Presence setting is estimated based on typical Marshall Silver Jubilee usage for clean/edge-of-breakup tones.
Reverb is set low; most sources and audio indicate little to no reverb on the riff.
Settings cross-referenced with genre and era conventions for accuracy. John Frusciante used a Fender Strat into a clean/edge-of-breakup Marshall Silver Jubilee, favoring a bright, mid-forward, and articulate clean tone with subtle reverb; these settings reflect the lightly driven, sparkling, and slightly compressed sound heard in the riff section of 'Under the Bridge.'
