It is mentioned by jesse that David Gilmour has not one but two lazy 20 combos

In a 2011 performance with Imelda May, Jeff Beck is seen using two Lazy J 20 1x12" Combo Amplifiers, as captured in a YouTube video by andron544.

In a video by TheGigRig titled "Radioheads New Touring Pedalboards Design, Build and Gig for Ed O'Brien and Colin Greenwood," it is confirmed that Ed O'Brien uses a Lazy J 20 18W 1x12" Combo Amplifier. The video, which provides a behind-the-scenes look at the setup for Radiohead's performances, shows this amplifier being used by O'Brien at the 5:45 mark. The video narrator remarks on the harmony between the Hiwatt and Lazy J amplifiers, stating, "It was beautiful seeing the amps that he was using, the Hiwatt and the Lazy J, the way they complemented each other."

Beginning with the 30 March 2010 Royal Albert Hall gig, Pete has used a Lazy J Model 20 amplifier and matching extension cab alongside the Fender Vibro-King amplifiers. (Vibro-Kings appear to also be on line, but shielded behind plexiglass.)

The amplifier is a copy of a tweed Fender Deluxe, and are made to order by Lazy J Projects in the UK. The amp is 18 watts, two channels, with one 12? Celestion Blue Alnico speaker.

In this interview, Bernard cites the Lazy J 20 as his favorite amplfier.

“Phil Harris called and said he’d found the best new amp he’d ever heard. The Lazy J had everything, but with its own character. Plus, it has a voltage control which acts as a master. The Normal and Bright channels affect each other’s tone, even when not in use. I asked Jesse (Hoff, Lazy J maker) to fit a spring and tremolo unit to give me my perfect portable amp. It’s my only amp for Trans. The only problem with my Lazy J is how long I’ll have to wait for a backup.”

"The Lehle Dual feeds my 1964 Vox AC10 Twin and Lazy J J20. The Vox is cross patched between both the normal and vibrato channels. The Lazy J uses the brilliant channel with the normal dialled in equally but not active. 1964 Grey panel Vox AC10 Twin: brilliant channel (high gain), out of low gain into vib/trem channel high gain. The Lazy J normal channel is active and colours the tone even when it is not plugged in."

In this video Tom Quayle tests his new pedalboard, through this amp.

In a video by That Pedal Show titled "Our Guitars & Gear: Dan’s Lazy J 20 Combo," Daniel Steinhardt discusses his use of the Lazy J 20 1x12" Combo Amplifier.

Freed also talks gear, with his Senn Pomona, 1965 SG Special, B-Bender equipped Pomona, Lazy J amp, and his minimalistic pedalboard.

"I try to use mostly the straight sound from the Lazy J amps without any pedals. If there was one pedal I could not be without it would be the ZenDrive that helps put the sound over the top for a really grimy tone that I like for solos." - Nalle Colt.

My Lazy J 20, which I take everywhere with me. Jesse Hoff who designed it absolutely nailed this amp. It’s loosely modelled on a 50s tweed Deluxe but it really has its own sound and the way it works is really unique. You can get everything you need, tone wise.

In this Instagram post from Stanton Edward, he shows his two amps he's playing in 2022 with The Wallflowers, a Lazy J 20, which he confirms in the comments, along with his Fender Deluxe Reverb.
