The core of the PSTX is made up of the Swiss models, cymbals that achieve a noisy, dirty, trashy sound quality by the use of specific layouts and varied sizes for the holes. Their silky surface distinguishes the cymbals visually.

The PST X Swiss Flanger Stack is medium-thin and thin in weight and produces earthy, dry and washy tone. Depending on how aggressively you tighten the pair, they offer a range from dry, trashy hi-hat sounds to shattering, noisy-washy crash effects.
