A twin-type pedal featuring a vacuum tube preamp reminiscent of PLEXI and an analog tremolo function. The MAGNUM59 preamp is a twin-type pedal featuring a vacuum tube preamp reminiscent of PLEXI and an analog tremolo function. Each can be used independently. There are many pedals in the world that are based on the PLEXI sound. When designing, HTJ-WORKS focused not on the "quantity" of sound, nor the "quality" of sound, but on the sound pressure. Absolute sound pressure during performance, without losing dynamics or picking harmonics, making the space vibrate. What was needed for that was, after all, the inclusion of a vacuum tube. The 12V DC voltage is boosted internally to over 200V. The MAGNUM59 is designed based on an amplifier. It's a warm, seductive sound, like THE HARD ROCK. This product is highly recommended for those who have never felt the characteristics of an amplifier in a pedal before. ■【Various Controls】 ● Right side: Preamp switch (red LED on) ● Left side: Tremolo switch (green LED on) ※ When using both effects simultaneously, the center lamp turns yellow. ◯ PREAMP ● VOLUME = Gain adjustment ● TREBLE/MIDDLE/BASS ● MASTER = Volume adjustment ● INTENSITY = Effect level send amount ◯ TREMOLO ● SPEED = Adjustment of the oscillation speed (can be visually confirmed by the LED) ● PLEXI/MODERN switch Two types of preamp characters ● FM/AM switch The sound's oscillation width changes Thank you for viewing.
