John Mayer’s Two Rock Combo

access_time First seen circa 2004

John was seen using the amp during a televised gig played on June 19, 2004 (video below). Based on the footage, the amp could be a K&M Jade model (which was in production around that time according to A List of Two-Rock Production Models from the K&M-Era) but it’s really really hard to tell anything for sure.

If you have knowledge of these early Two Rock combo amps and happen to recognize the one on the video, be sure to get in, touch. Until we manage to identify it, the amp will simply be listed as a “Two Rock Combo”.

Fender '65 Princeton Reverb

John has used this amp occasionally on stage with Dead & Company, circa 2017. To which purpose he used such a small amp for stage performance is unknown, but could perhaps be that he simply liked the reverb on the amp. Embed from Getty Images

Fender Dual Professional

This amp became a part of John’s usual stage setup from around the same time he began using the PRS J-MOD 100 amp – his own signature model from PRS introduces in early 2017.  Usually, with Dead & Company, he would have the Fender Dual Professional sitting between two J-MODs, and a Victoria Reverberato unit sitting on top of it.

Two Rock Custom Reverb

John started using Two Rock amps sometimes prior to the 2004 summer tour (if you know of a specific date when he started using them, please leave a comment below) and continued using them as his main amps over the next few years. In 2004 specifically, he was mostly seen using a single or two Two Rock Custom Reverb heads, sometimes with the cabinets rotated backward, and sometimes with a Fender […]

Fender ’65 Super Reverb Reissue

Used during the later part of the Room for Squares tour starting from 2002. The amp can be seen during the concert in Birmingham, Alabama which was released as a live CD and DVD titled ‘Any Given Thursday’, and on the music video for the song ‘Why Georgia’ – which also shows some backstage footage, as well as on some 2003 gigs (see photos from Elton John AIDS Foundation’s 11th Annual Oscar […]

Fender Hot Rod Deluxe

This guitar amp was seen sitting behind John onstage during The Andre Agassi Charitable Foundation’s Show at MGM Grand in Las Vegas, Nevada on October 2, 2004 (photo below). Given that the amp is mic-ed up, and positioned right behind John, it seems most likely that it was used by him (as opposed to someone else in the band). However, this seems to be the only occasion during which the amp was […]

Fender Tonemaster

This is the amp that was often seen next to the Super Reverb on stage during the Room for Squares tour circa 2002. It is unknown whether John actually used this amp since it could’ve been used by the guitarist standing to his right (if you happen to know who exactly played guitar with John around this time, please get in touch).

2004 Fender Vibro-King Limited Edition

John was seen using this amp on occasions in 2004/2005 alongside a Two Rock Custom Reverb. Based on the photos, the amp that John used was a limited edition which was available only during the 2004 NAMM show, with Western Hand Tooled Tolex, and a matching cabinet (for reference and photos, see 2004 Fender Vibro King Cowboy Tolex Amplifier).

Fender Vibro-King

This seems to be the amp that John used in the earlier part of the Room for Squares tour, based on the footage from ‘Your Body is a Wonderland’ video (photo below), and on some live footage recorded in 2001. It is possible however that the amp was not always used by him (see photo below, the amp is used by the person on the left).

This has been John’s main amp since circa 2017, when it first became available, both with Dead & Company and on his solo gigs. He’d usually have two amps sitting on stage, with a Fender Duo Professional sitting in between them, and a Victoria Reverberato Reverb/Tremolo unit sitting on top of it.

Fender Deluxe Reverb Amp

According to a Periscope stream that John did in 2015, this amp was built by Chris Flemming from the Fender Custom Shop. Chris apparently had help from Alexander “Howard” Dumble of Dumble Amplifiers. John mentioned using the amp while playing American Pie on David Letterman, and on tons of other stuff (although he doesn’t go into specifics, unfortunately).
