Josh Homme has used the Pultec EQ1A Equalizer in his studio equipment setup.
At 0.18 you can see a pair of original Pultec EQP-1a EQ units sitting in his rack.
"These Pultec Eqs are very old, very sought after and sre probably around $7-8,000 each. When I got them years ago they were cheaper," says Steve Vai about the Pultec Program Equalizer EQP-1A which he uses in his studio equipment setup.
You can just spot a pair of the EQP-1A's in the rack in the video at 4:22 at Prince's Paisly Park.
Used for the ending guitar solo in "Walk This Way", as stated by engineer Jay Messina in this March 21, 2017 Mix Online interview.
The guitar solo that ends the track in a fade is all one track, Messina says. “When we mixed, that was probably a 30 ips delay on the opposite side of the lead track, which is what gives it that spread,” he says. “That was probably a Fender Twin. At Record Plant, we used to have these vintage amplifiers. They were small amps that had really meaty power without tearing your head off with volume. Probably three mics [were used]: a Sony C37, which provided the meat and bottom end of the sound, an SM57, and a Sennheiser MD421, which provided the edge. The combination of all three was compressed through a UA 1176, followed by some boost at 5k in a Pultec EQP-1A.”
In the video titled "INSIDE: Charlie Puth Home Studio" by Caleb Simpson on YouTube, at the 0:05 mark, a pair of Pultec Program Equalizer EQP-1A units can be clearly seen positioned in an Argosy Eclipse rolling rack on the right side of the screen, confirming their use in Charlie Puth's studio setup.
In a post on Instagram, Wolfgang Gartner hints at upcoming music releases while featuring the Pultec Program Equalizer EQP-1A, a key component in his studio setup.

Bob Dylan's sound engineer says, "Digital is fine as long as you record what you want to hear. I use Neve 1073 and Pultec EQP1A EQs, [Universal Audio] LA3 compressors, and dynamic microphones through tube preamps to get the sounds I want before they’re recorded," in this article about recording Bob Dylan.
KSHMR used it to boost some frequencies on the vocals of his track "Extreme", with the Bassjackers
Second on Andrew's blog post for home mastering. Andrew says, "The curves on this EQ just seem to have a very musical shape. I give a boost around 60hz for my low end presence and I like a broad bandwidth lift at 12khz to make things sparkle. Both of these I'll dial in to taste, but on the boost knobs I rarely go above 3 for treble and never above 2 for bass. The occasional mids-heavy track will also benefit from a mild dip at 500 or 700."
