In this March 1, 2021 Guitar World article, EVH's guitar tech Tom Weber explains that Eddie had three custom Dunlop picks, a red, white & black 'frankenstripe' pick (most likely Max-Grip .60), and two custom-molded EVH Herco Flex 50s in silver (onstage use) and gold (backstage handout).

"Weber went on to explain that Eddie had a red, white and black striped pick, and also a “Herco 50 in silver, which were the picks that he played onstage. And then we had the same thing in a gold pick, and he carried those around in his pocket basically so that if he wanted to hand one to somebody, the only way you were gonna get a gold one is from Ed himself."

In a photograph of Kevin Shields' pedalboard from 2008, Dunlop Herco Flex 50 Nylon 0.65mm Guitar Picks can be clearly identified in the bottom left corner, situated next to his Ibanez AD9.

In this article, it says, "Cragg uses D’Angelico 80/20 Brass strings (.012–.054) on Young’s acoustics, and Dean Markley Super V’s (.010–.046) on his electrics. Picks are nylon Herco Gold Flex 50s. “Neil used those when I first started working for him, and he still does today.”

A detailed gear diagram of Robin Finck's Nine Inch Nails stage setup, traces the signal flow of the equipment in his 2014 guitar rig. Herco Flex 50 Picks are seen as part of this set up.

In a Facebook post by "The Professionals - COOK 'N' JONES and all the others," it is confirmed that Steve Jones uses Dunlop Herco Flex 50 Nylon 0.65mm Guitar Picks.

Duffy's official website states that Duffy has been using Herco Flex 50 picks since roughy 1978, recommended to him by Johnny Thunders.

"DUNLOP HERCO PICKS"

"Billy always plays with Dunlop Herco Flex 50 medium guitar picks and was first turned onto them by Johnny Thunders as he explains here… “Thunders gave me one of those picks, himself, back in ’77 or ’78 when he was playing Manchester University. He was at a payphone and he pulled one out of his pocket while he was on the call and handed it to me. I’ve never played anything else since. Another thing: I play with the pick “sideways,” compared to the traditional grip, and always have done. Not a lot of people know that.”

"For a number of years Billy has had his own custom versions made exclusively for him by Dunlop and initially they were embossed with DUFFY and an Iron Cross graphic and made in Manchester City Blue and then Gold (to celebrate City winning the English Premier League in 2012)."

"The current design is an embossed Billy Duffy silhouette logo and are made in white and black to match his Gretsch Signature Falcon Guitars."

Billy Duffy's official website states that Thunders turned Duffy onto Herco Flex 50 picks while touring around roughly 1978.

"Billy always plays with Dunlop Herco Flex 50 medium guitar picks and was first turned onto them by Johnny Thunders as he explains here… 'Thunders gave me one of those picks, himself, back in ’77 or ’78 when he was playing Manchester University. He was at a payphone and he pulled one out of his pocket while he was on the call and handed it to me. I’ve never played anything else since. Another thing: I play with the pick 'sideways,' compared to the traditional grip, and always have done. Not a lot of people know that.'"

In this article from March, 1977's edition of Guitar Player Magazine, Bolin states that he uses Herco Gold "heavy" gauge guitar picks, chewing them with his teeth for a length of time before concerts to make them more flexable, as Bolin describes it a "feeling somewhere between a heavy and medium thickness" pick.

WHAT ABOUT YOUR EQUIPMENT?

BOLIN: I'm using two HiWatt tops with four Sound City bottoms. The Stratocaster I use is a stock 1963. It's very hot, and I really don't know why. I use Ernie Ball Extra Super Slinky for the Strat, because my hands aren't very strong. I use heavy picks, Herco gold, but I chew them all day first. It loosens them up and gives them a feeling somewhere between a heavy and medium thickness. [Ed. Note: Bolin also had two other Strats, one with a Telecaster neck, an Ibanez Explorer he used for slide playing, and a $160.00 Yamaha Acoustic that sounded great.]

DO YOU PERFER THE HIGHTS OF A FENDER TO THE THICKER GIBSON SOUND?

BOLIN: Yes, I like the cutting sound of a Fender. With Les Pauls, at least for me, I can get only two or three different tones. That's it. But with the Strat, I can use it on about everything I play. I keep the amp on full bass with no treble and also use a Sam Ash Fuzztone [manufactured by the Sam Ash Music stores of New York, no longer available]. You can't get those anymore. I have the fuzz on all the time with attack, volume, and tone all the way up. It doesn't sound like a fuzz, really. It just gives the guitar so much more bite and attack.

HOW DO YOU GET SUCH A SMOOTH TONE WITH THE FUZZ ON ALL THE TIME?

BOLIN: Having the bass up on the amp is the ticket. Plus you have to work a lot with the tone controls on the guitar. You have to use a lot of bass, because the Strat has such a thin sound. The tone I have now is somewhere between a Strat and a Les Paul. [Ed. Note: Bolin also utilized a phase shifter, built by a roadie, and an Echophlex, which he mounted waist high for access onstage.]

ONE OF YOUR CHARACTERISTICS AS A GUITARIST SEEMS TO BE TRIPLETS. DO YOU HAMMER YOURS OR PICK EACH ONE?

BOLIN: I probably play them too much. I pick each one. I think the ability to do that, again, comes from the drums. The drums strengthened my wrist, which allows me to keep my picking hand relaxed when I play. That's important, and it comes form doing it for a long time. How good you play triplets, or anything really, comes from the way you say something with the guitar, the way you attack the notes. You have to attack with confidence. Practice gives you that, I guess. For me, practice isn't doing scales but doing things like writing, jamming with other people, or playing gigs.

LOOKING BACK, WOULD YOU HAVE DONE ANYTHING DIFFERENTLY?

BOLIN: A lot of times I wish I would have learned to read [theory]. But I'm very impatient. I used to try and take things in leaps and bounds. Now I've realized it's got to be step by step.

[V.G.]: How are your Stratocasters set up?

[M.R.]: I have the tremolos blocked off – I don’t use the wang bar at all. It’s too trendy. In fact, I don’t even screw in the bars.

[V.G.]: What kind of strings and picks do you use?

[M.R.]: Ernie Ball Regular Slinkys, .010-.036, and Herco gold picks. I like that rough grip they have. When I play, I turn them around and use the round side so I can get harmonics. I grip so there’s only a little bit of plastic showing, and use the rough edge to scrape the strings.

Tom says he has used Herco 50s since 1972 around the 4:50 mark. because he likes the grip on them.

His older gear remains at home.

“I have a very small collection,” he explains. “I’m not like Neil or Stephen.”

In addition to his Springfield-era ’59 ES-355, he owns a ’61 D-28 that stays home, a ’53 J-200, ’55 Gretsch Roundup, and a ’57 Gretsch Chet Atkins. He really likes his D’Angelico Excel ASG 100 and EX DC Standard, and Herco Golds are his longtime pick choice; he uses GHS Bronze strings.
