・EVA Electronics PHC-VIC 30V Variable Impedance Control ・Purchase Price: ¥36,300 (tax included) ・Unused item, stored at home ※This is a stabilizer that allows for stepless adjustment of input impedance from high impedance to low impedance. It boasts an overwhelming dynamic range with 30V operation. Input impedance can be adjusted steplessly from 2MΩ to 50kΩ. The impedance of many passive guitars is 250kΩ to 500kΩ, but the common 1MΩ input is too wide, allowing extra noise and unpleasant frequencies to enter. By gradually reducing the knob and tuning, unwanted, scratchy, and spiky bands are removed, giving the impression that only the original thickness and brilliance of the guitar (bass) are extracted. By supplying an external power supply of DC9-18V, it is boosted to 30V and stabilized by a newly developed power supply circuit for operation. #EVA Electronics #Eva Electronics #EVA #Eva #PHC-VIC30V #PHC #VIC #30V #Sound Stabilizer #Variable Impedance Device #Variable Impedance #Impedance #Buffer Amplifier #Buffer #Effect Pedal #Bass Effect Pedal #Effect Pedal Board #Pedal #Pedalboard #guitar guitar #bass #bass #Preamp #Enhancer #Comp #Compressor #Equalizer #Wide Range #Piezo #Wood Bass #Acoustic #Acoustic Guitar
