The Nine Zero Two is a versatile yet simple overdrive / distortion based on multiple discrete transistor gain stages placed in series. Each stage in the series uses a different type of gain circuit, resulting in a complex, nonlinear amplification response – a response that approximates the rich harmonics of overdriven tube gain stages. They’ve also included a simple, amp-like tone stack to complete a very familiar overdrive package. Underlying this outward simplicity is a wide range of tone possibilities, with gain ranging from light dirt to smooth saturation. And yes, ‘902’ is the telephone area code for Nova Scotia, the home of Diamond Pedals.
