BOSS ST-2 Power Stack This is a BOSS drive pedal developed with the powerful sound of vintage stack amps as a reference. It achieves everything from a fat, crunchy sound with good note separation to a fierce distortion that surpasses a fully cranked stack amp, all with a single SOUND knob. It also has TREBLE and BASS knobs, allowing you to correct the sound to match the desired sound or band ensemble. The ST-2, which achieves a wide variety of sound creation while being a compact pedal, will be active in any situation. This BOSS distortion pedal was born by thoroughly analyzing the characteristics of vintage stack amps. It realizes the powerful distortion sound that many guitarists long for, which shakes the air, in a compact pedal. It also achieves the delicacy of a vacuum tube amp, which dynamically responds to picking nuances. In addition, it supports a wide range of sound making with simple operability with four knobs. It works regardless of genre. The SOUND knob, which simultaneously changes the amount and character of the distortion, realizes a variety of sounds. On the left side of the knob, you get a crunchy sound with softness and a bell-like tone, and in the center, a powerful drive sound like a vintage stack amp played at a high volume. Furthermore, turning it to the right creates a fierce distortion sound, as the name ULTRA suggests, as if a booster was added to a fully cranked stack amp. ■ Guitar Effects Pedal ■ Power Stack ■ Controls: Level, Bass, Treble, Sound ■ Power: 006P (1 piece), AC adapter (PSA-100) ■ Current consumption: 36mA (DC9V) ■ Dimensions/Weight: 73(W) x 59(H) x 129(D)mm, 440g The item for sale this time is "like new". I bought it experimentally when using a Stratocaster, but I have only used it (connected and played) a few times, and there are no scratches. Of course, it works without any problems and comes with the "instruction manual and box". It's almost like new, but it's still "used", so please refrain from purchasing if you are sensitive to such things.
