Thank you for viewing! This is the JEN TD-1 Platinum Drive. It's a distortion pedal that uses a vacuum tube. Please note that it runs on AC power. ☆ Operation has been confirmed. I'm not sure if it's because of the tube, but the tone on the high frets is very glossy and sounds quite good. The gain range is honestly so high that you only need up to the 12 o'clock position on the knob. Around the 9 o'clock position is where the tone is the most glossy, and I recommend it. Each knob has a click, so fine adjustments are easy. Also, it doesn't move easily if you just brush against it, which I think is also a merit. It seems that many people change the vacuum tube to a 12AU7. Both the tube and the op-amp are socketed, so you can enjoy changing them to your liking (see photo 5. Only photo 5 is a photo from when I purchased it). Recommended for those who want to add personality to their pedalboard. Because it looks tough!
