The Diamond Nine Zero Two is an all-new orverdrive circuit from Diamond, having been in the works for years.
The process of developing the Nine Zero Two began as a series of transistor gain stages all lined up in a row. However, each of these gain stages is a different type of circuit, to maximize the amount of harmonics present in the signal.
Much like a real-deal tube amp, the Nine Zero Two is engineered for maximum harmonics for a rich creamy overdrive that stands out from the rest of the pack. The requisite Tone control governs the brightness or darkness of the effect, and was deliberately engineered to lend an air of familiarity to the drive character.
