Thank you for viewing! This is a HIWATT wah pedal. It's a manly pedal with a metal chassis! The sound is also manly! It's not your average wah. The Q control knob on the side has a unique range. And the treadle is like a metal file! Manly! It's heavy. After purchasing it new, I touched it a few times and it has been sleeping for a long time (*˘꒳​˘*) Zzz... If you are looking for a wah like a Crybaby, I have other wah pedals for sale, so I would appreciate it if you would consider those. The AC adapter seems to be center-positive, and I couldn't find that type of adapter, so I haven't been able to check it. I have only confirmed the sound with batteries. ★ There is no scratchiness, but there is the inevitable wah noise. If you don't like wah noise, I have a BOSS V-Wah for sale, which uses infrared for the treadle, so there is no noise. Recommended! ★ Smoke-free, no-pet environment. ★ One-owner item. ★ However, it is an old item, so I cannot guarantee its operation m(_ _)m ★ No claims, no returns, please m(_ _)m ↓ The following is an explanation by AI, but the brand name is wrong (*^^*) 【High-Quality Wah Sound】 The I-WATT wah pedal is an essential effector for guitarists. It creates a variety of tones and adds depth to your performance. 【Durable Design】 The silver metal body and grip tape surface are designed to withstand long hours of use. You can use it with confidence on stage. 【Easy Connection】 It can be easily connected using a 1/4-inch jack, and the volume knob allows for smooth volume adjustment. - Brand: I-WATT - Type: Wah Pedal - Color: Silver - Surface Material: Grip Tape - Connection Terminals: 1/4 inch jack - Adjustment Knob: Volume Knob Thank you for viewing.
