" - What kind of guitar synthesizer do you use on the solo record? (1978) - I used an ARP Avatar, I called them up and told them that I wanted to use their synthesizer and said that I would endorse it for them, and they said, ah, well, you know, they’d take $150 off the price, $200 maybe, and I said, Oh, I won’t bother then. If they want to take a few hundred dollars off, big deal. [Ed. Note: An ARP spokesman responded that company personnel were pleased when they learned that Ace was interested in using their products, and they recognized that Kiss could introduce synthesizers to a new, younger market; however, as a matter of policy ARP does not trade equipment for endorsements.]"

"My studio was called Pi West, and the initial bank of keyboards there when John and I started out working together were the Sequential Circuits Prophet 5 Rev3, a Prophet 10, an early ARP Quadra and two ARP Avatars — one Avatar was integrated with a Sequential Circuits Model 700 programmer — an ARP Sequencer, an Oberheim Four Voice, and an Emulator 1 sampler. I also had the Linn LM1 drum machine, which drove our main arpeggiator, the ARP Sequencer, using clock pulses."

“I went to the London Synthesiser Centre and picked up an ARP Avatar, which looked like a Moog and had a setting called Hex Fuzz that I liked,” he tells us from his studio in the States. It came with a pickup that would go into my guitar, and I ran it through a little telephone extension speaker or my Fender Twin. I got a lot of the ambient sounds for ‘India’ off that, and the solo for ‘Fall’. I learned how to do the same thing with gain and distortion in the end – it’s a lot less hassle!”

"New toy in the house! And after getting all the pre-done mods right and exchange bad pots with better ones, it'a great modular Avatar now. And added some of my mods also..."

In a review from Muzines, Paddy Kingsland discusses his use of the ARP Avatar synthesizer.

In an interview with Canadian Musician magazine, Domenic Troiano mentions, "I just got an ARP Avatar and want to learn how to use it. I want to try some other synthesizers as well. I haven't bothered with the synth up till now because you had to alter your touch so much; it wasn't like playing guitar. They seemed to have solved that problem and now they have to overcome the polyphonic thing. The Avatar is great but to play one note all the time is a drag. They're coming up with new technology all the time." This confirms that Troiano uses the ARP Avatar synthesizer.
