Tunstall’s pedalboard is complex. The most important element remains her Akai Head Rush pedal. She’s been building loops with it since the beginning of her recording career. But there’s a lot more in the signal chain. Tunstall plugs her guitar into a Boss SY-300 Guitar Synthesizer (sitting just off the board), then a Boss LS-2 Line Selector, which splits the signal to two signal chains–one for FOH and one to her amp.
Her amp signal starts with at Boss TU-3 tuner, then a Supro Drive, a Supro Tremolo, a Boss SD-1 Super Overdrive, a Boss CE-2w Chorus, and an Electro-Harmonix Holy Grail reverb.
The FOH signal chain starts with another TU-3 before hitting a Boss OC-3 Super Octave and then a Klark Teknik DN200 DI. The Klark splits the signal out to FOH and a Mackie mixer that Tunstall uses to submix a vocal mic, a direct guitar signal and a Roland Handsonic HPD-10 before hitting the Akai Head Rush. From the Head Rush, the signal goes back into the other channel of the Klark and then finally to FOH.
