Typically thought of as a "second string" pedal, a Compressor's creative capabilities are often overlooked due to pedalboard space constraints or the subtlety of the effect. The Guyatone ST-2 Compressor/Sustainer puts all these arguments to rest, offering extreme amounts of compression in an incredibly compact stompbox format. The ST-2's variable Level and Sustain controls allow you to dramatically "squash" the input signal, yielding smooth, clean bell-like notes that last for days. In addition, the ST-2 features a direct on/off switch. When engaged, the direct switch blends in a dry input signal at equal volume with the compressed signal, eliminating the attack-altering characteristics common to other compressors. By manipulating these three controls, the ST-2 can be used for a wide variety of applications. With the Sustain control set at maximum, the ultimate "chicken pickin" Guitar tone can be attained. With Sustain at minimum and the Level control above 12 o'clock the ST-2 can be used as a clean booster, perfect for overdriving the front end of an amp. Varying the Sustain and Level controls further will yield everything from subtle compression to signal limiting to note attack-altering effects similar to the SV-2! The ST-2's full-frequency response makes it ideal for use with any instrument including Guitar, Bass and Keyboards.
