When it comes to pitch-related effects, isn't DigiTech the go-to brand? I found it invaluable for drop tuning in metal sounds!! It's especially recommended for those who don't want to buy a multi-effects unit! You don't feel much latency, and it functions as a pitch shifter without any issues! Comes with an unopened DC adapter! A red guitar effects pedal capable of 7-step pitch changes. - Model Name: DROP-V-01 - Function: TRUE BYPASS - Color: Red - Controls: Knobs and switches - Country of Manufacture: China - Output Terminals: Guitar output - Number of Settings: 7 settings - Brand: DigiTech
