Blackstar HT-DRIVE Effect Pedal Used overdrive pedal. I believe I am the second owner. I used it a little when I first bought it, but it was very heavy and difficult to use because it's 22V, so I kept it in storage since then. There are no issues with the sound or operation. It uses a vacuum tube boosted to 22V, producing a thicker sound than other effect pedals. The box is damaged, and the main unit also has many scratches if you look closely. Included accessories: Instruction manual, warranty, original adapter. Shipping is planned via Letter Pack Plus, but if it doesn't fit, it will be via Mercari delivery.
