Memories In The Studio With The Sony DPS-R7.

In a quaint and quirky recording studio, I once had the pleasure of witnessing a comical incident involving the Sony DPS-R7 reverb processor. It was a session with a band known for their eccentric personalities and experimental sound.

The guitarist in the band had a penchant for using effects in the most unconventional ways. He was convinced that the Sony DPS-R7 was the key to achieving the otherworldly sound he had in mind. As the session began, he insisted on putting the DPS-R7 on everything, from guitars to vocals and even on the drum kit. It was as if he believed the reverb unit held the secrets to intergalactic audio exploration.

Unbeknownst to us, the guitarist had a mischievous streak. He had set the DPS-R7 to one of its wildest and most extreme reverb settings. As the drummer launched into a thunderous drum fill, the guitarist triggered the DPS-R7 with a wicked grin. What followed was nothing short of a sonic tsunami.

The room filled with an ear-piercing reverb wash that seemed to go on forever. The drummer’s drum hits transformed into elongated, psychedelic echoes that left everyone in the studio in stitches. It was like being caught in a time warp of sound, with each snare hit echoing back like a never-ending punchline.

The band, far from dismayed, found this hilarious twist to be the most entertaining thing that had happened in the studio in a long time. They couldn’t stop laughing, and even the normally composed engineer had tears in his eyes.

As the reverb slowly subsided, the band decided to keep the over-the-top drum sound, which they lovingly referred to as the “Galactic Snare.” It became a signature element of the song, and they even added more doses of the DPS-R7’s extreme reverb to other tracks. What started as a prank turned into a defining feature of their music.

The Sony DPS-R7, in the hands of this audacious guitarist, had unwittingly become the studio’s resident prankster, dishing out cosmic reverb jokes that left everyone in hysterics. The lesson we learned that day was that, in the world of music, sometimes the most unexpected and humorous accidents can lead to creative breakthroughs and memorable moments. The DPS-R7, in its own peculiar way, had added a touch of humor and uniqueness to the recording session, and it was a day we’d never forget.
