"From the effects send on the Boogie, I go into a T.C. Electronic 2290 and a Yamaha GEP50. I've got a Roland GP8, too -- those guitar processors are okay if you use them together with another effect. And I've got the wonderful Eventide Harmonizer, which I use for some of the expansive stereo choruses. I haven't used my Roland GR-50 guitar synthesizer onstage yet, but I'm planning to. The controller is a GK-2."

Entrevista a Barakus (el gutiar tech de Gustavo cerati). en el minuto 4:25 cuenta que el usaba la pedalera Roland GP-8. "Ahi estaban todos los sonidos de Soda".

"This rack over here, at the end, is what we call the guitar rack. You've got a valve preamp and a Roland FC100, which I can use in conjunction with this GP8. All of these get put through the Yamaha DMP7, a digital mixer, where all my patches are stored. One recent thing is this Quadraverb unit that just came out. It does reverbs, delays, choruses and EQs all at the same time, instead of having to have four separate units. A lot of the sounds on our records are made up not by just, say, getting a piano, but by taking a piano and sort of messing about with it through all this type of stuff."

In the magazine International Musician And Recording World from June 1990 we can read :

"Belew's rack is a serious affair - and there are two of them in case one goes down: "There's the GP8 and GS6 ganged together, the GP8 is very noisy and the GS6 has the ability to quiet that down. The G96 also has stereo delays and choruses, and has several guitar sounds that I like that I developed - they sort of sound like Vox amplifiers. There's a Roland pitch shifter, which is a mini rack device. The only thing I use that for is backwards guitar. The two A3s have a variety of sounds that I like, they're very warm sounding units and have modulated delays that actually sound like a double guitar."

"The guitar is DI'd through a GP8 guitar processor and goes via a couple of modules from the original Manor desk; the compressor module is used to really squeeze the Strat sound. You want the guitar to still sound like a guitar-but I might put some flanging underneath, as well as dense, long echo. I'll also use the Eventide Harmonizer on rnost of the sampled guitars. All the guitar parts are DI'd using a processor-miking up an amp is OK for some styles, but I've been using a processor for the last few years and find that I get more precision-more control. It's also more practical when the studio is being operated by one person."

McCabe's search for new sounds saw him go through a dizzying array of effects for the recording of A Storm In Heaven. "I love buying gadgets, and I go through loads of different setups, so what I use changes constantly," he confessed. "For guitars, my standard Strat is the one I really like, and I also have a Gibson ES-335 for a lot of the feedback stuff. I've got a Jazzmaster which I bought mainly 'cos I liked the shape....and then I found out how shit it was. It was TomVerlaine's fault, as usual." "My main Marshall packed in and started to sound horrible just before we recorded the album so I got hold of a Mesa /Boogie (MkIII) combo. For effects I started off with a Watkins Copicat and I used to have one of those old Roland Space Echoes, but at the moment I 've got a Roland GP-8 that I picked up second-hand. It's pretty reliable, it does the job. But in the studio, it's just a case of using anything I can get my hands on - a GS-6, a Roland Jazz Chorus combo....I hooked those up after the Mesa/Boogie, and it's that which gives the great big sound on The Sun, The Sea. "I come up with new ideas just by dribbling guitars over everything and picking out something that makes some sort of sense," he continued."We sample stuff, loop bits I've played and it's sounds great. John(Leckie) has actually tamed me down a bit, really. But live it's different - we never try and exactly recreate the studio sound and I think all our songs will always take on a different character when we play them live."

"I used those with a variety of rack effects like the Yamaha SPX 90, and TC Electronic 2290, and Eventide H3000 in a stereo set up. A little later I also used a Roland GP-8. Slightly off topic, my Dad liked the sound of many of my presets on the GP-8 so I went to Guitar Center and bought him one. I copied all of my presets into it and he used it extensively on his 1988 tour. The clean sound that you hear him soloing with is him playing his blonde Performance Guitar through the GP-8."

According to Guitar Geek rig diagram (which was made around the time BRMC recorded their debut album in 2001), Hayes used Roland GP-8.

Naiv studios worked on re-designing Skee Masks's studio space in 2020. Photos taken by Luis Zeno Kuhn of the finished room reveal much of Skee Mask's gear and workspace. The photos were found on the Naiv studios website under the index section that shows work done for previous clients.

"I think it was on the Tunnel of Love tour that I had all of these foot pedals with chorus and delays running together, and they got so noisy! So I challenged myself to learn how to use a rack-mounted thing. That's how I acquired those [Roland] GP-8s, which are programmed for the E Street Band and my solo work."
