The British Rockgitarrist- and singer Eric Clapton used a "Yamaha GEP 50" from 1989 to 1996 as part of its Soldano / Cornish Guitar routing system , which by Pete Cornish and Michael J. Soldano, Jr. was developed. The effects device was used in the system during Clapton's Journeyman World Tour , his 1992 world tour and rehearsals for the From the Cradle World Tour . It can also be heard on the studio album Journeyman and the live album / video 24 Nights . Other artists who use the audio processor include the English singer-songwriter Bilinda Butcher, the German guitarist Julian Wolf, the Australian guitarist Peter Mengede, and the British rock musician Johnny Marr . Guitarist Joe Walsh of the Eagles promoted the device in the 1980s and put it:

“I've used all kinds of effects and I throw most of them away because they don't make sense for the guitar. What you get for the effect isn't worth putting in your signal path. The GEP 50 is really guitarist-friendly. It offers the widest variety of usable guitar effects that I've come across, and you don't have to go back to college to learn how to use it. I can run through all the programs, change the parameters easily, and get a varied and wide assortment of really appropriate sounds. The GEP 50 gives me things I wasn't initially going for. But I always end up with a great guitar sound. It never lets me down. "

“I've tried all sorts of effects pedals and I throw most of them away because they don't make sense to the guitar. It's not worth the effect you get to drag through your signal. The GEP 50 is guitarist friendly. It offers the greatest variety of useful guitar effects I've seen, and you don't have to go back to college to learn to use it. I can switch through all programs, change the parameters easily and get a large collection of sensible sounds. The GEP 50 doesn't give me the things I originally wanted, but I always end up with a great guitar sound. It never lets me down. "
