Phil Collen

In this video, Phil Collen mentions he uses the Mesa Boogie Dyna-Watt 20/20 power amp in his rack rig.

In the Jackson Guitars demo video, Phil Collen is seen using the EVH 5150 III 100-Watt Tube Head.

Phil Collin uses blackstar silverline. I have seen numerous video clips of him playing the silverline when giving demos on how to play def leppard songs. You can see the silverline he is plugged into on this clip (the marshall is not being used)

"On Pyromania the guitar sounds were recorded using a Marshall 100 watt amp." The image shows a Marshall JCM 800

"Yeah, absolutely. I actually use a Cyber-Twin as well. Actually, I was on Jimmy Fallon -- I jammed with the Roots and everything -- and I played this Cyber-Twin. And I loaded all my presets from home on to the one in New York, and it sounded exactly the same. And actually, the big gig we’re doing next week -- I’ve got my Def Leppard C rig, which is my Marshall JMP-1, which I’ve been using for like 15 years, and a Fractal. And it’s my C-rig – we have an A rig, we have a B rig, and we have a C rig."

You can see at 33:18 the gold Marshall preamp in the rig.

"[Interviewer:] From a guitar perspective, is it true that there are no traditional amps on Hysteria and that you and Steve Clark played all your parts through a Rockman unit, which is essentially a headphone amplifier?

[Collen:] Pretty much. I used a small Gallien-Krueger amp on the demo for “Love Bites,” which made it on to the record, and also on a bit of “Animal”—that little feedback thing in the intro is me leaning hard on the Krueger. But otherwise the sound is all Rockman. And the reason for that was there were so many layers of tracks, and the sound was so huge that if you had had a massive Marshall sound it wouldn’t have fit sonically. The guitars would have smothered the vocals and drums. They really had to fit in a specific slot. Plus, Steve and I weren’t playing straight power chords; we were doing all these inversions and partials and different things that required definition. That would have been lost with a big, overdriven-amp sound."

" Fender put this little G-Dec. Do you remember the G-Dec? You could punch in and you could just play with them. It was the second G-Dec, it wasn’t the very first one. It was the second one, which I still use. It sounds great. I’ve actually done gigs with it. Me and Debbi actually did a thing in a theater, and I’m like, “There’s no way I’m going to hear this thing.” But I put it there anyway. I just tilted it up and used this thing and it sounded killer. So, it shocked me. I actually just used one of the standard presets on there as well and like, “Wow!” It was on fire!."

Used for Hysteria, as stated by recording engineer Nigel Green in this 2017 interview.

When Mutt finally arrived on the Hysteria album he didn’t want to go through that again so we decided to go for processed guitar sounds using something called a Rock Box. Other times we would us a Rockman, made by Tom Scholz. The Rock Box had similar settings to the Rockman: a clean sound and a distorted sound. The difference was you could turn off the chorus and effects on the Rock Box allowing you to use your own effects.

So the plan was we were pretty much going to use either the Rockman, or Rock Box for everything guitar wise. If the sound was not right after we added EQ or some outboard gear then we’d maybe change to a different guitar or add some kind of effects pedal. Sometimes I would blend a Roland studio flanger in to beef some of the power chord sounds. We pretty much would try anything to make it work, but in the end if it wasn’t cutting it Mutt and the band would change the guitar part altogether.

In this interview previously published about the Rockman x100 being used on Hysteria, Phil Collen mentions a small Gallien-Krueger amp that was also used in “Animal” and “Hysteria.” The amp is none other than the Gallien-Krueger 250ML that was manufactured throughout the 80s. It produces sounds that very closely mimic the Rockman, but with much more power at 100 watts!

In this Youtube video Phil demos his signature model played through an EVH 5150. It’s a 100W EL34 model because of the gold color and position of the knobs.

Phil Collen is confirmed to have used the Randall RG100HT guitar amplifier head, as evidenced by an article on steveclarkguitar.com. The article states, "Both Phil [Collen] and Steve [Clark] use a sound system [for this tour] consisting of a Randall RG100 guitar pre-amp and T.C.1210 from TC Electronics (Expander + stereo chorus / flanger) and a T.C.2290 (digital delay)." Additionally, the image above from the 1980s shows Steve Clark’s rack containing three rackmounted Randall RG100HT amplifiers, further supporting this claim.
