Mick Grondahl

At 40 seconds into the video "Jeff Buckley - Last Goodbye | 120 Minutes | MTV | New York | 1/10/1995," Mick Grondahl can be seen playing a Fender Jazz Bass. He has also used this instrument in the majority of Jeff Buckley's shows and likely used it to record the album "Grace" (1994).

In the YouTube video titled "Jeff Buckley - Grace (from Live in Chicago)," Grondahl's amplifier, positioned to the left of the drum riser, can be identified as a Mesa/Boogie Bass 400+ Amp Head, paired with a custom-built matching Mesa/Boogie cabinet featuring a slanted base. This amplifier was used during Buckley's 'Mystery White Boy' tour and is likely the source of the overdriven tone on the track 'Eternal Life' from Buckley's studio album 'Grace' (1994).

In the YouTube video titled "Jeff Buckley - Grace (from Live in Chicago)" on the jeffbuckleyVEVO channel, a Mesa/Boogie Road Ready 4x10 and a Mesa/Boogie Road Ready 1x15 bass cabinet can be seen positioned behind bassist Mick Grondahl.

Mick Grondahl, the bassist for Jeff Buckley, confirmed in a discussion on TalkBass.com that he used the Electro-Harmonix Sovtek Big Muff for recording Grace, Sketches for My Sweetheart the Drunk, and during live performances.
