Custom Tones Ethos Overdrive. I've used this with care only in my room, so I don't think there are any noticeable scratches. This is famous as a Dumble-style overdrive, but personally, I think the clean channel is exquisite. I've connected it to vintage Fender amps and Two Rock amps, and it made the clean sound of tube amps even better. I also owned Klon and EP Booster as clean boosters, but this was easier to use than either of them, and I enjoyed the clean sound more. It's easier to understand than a Klon (perhaps Klon is for experts), and the level control is easier to use than an EP, allowing for fine adjustments. As a result, I got rid of the others and kept this Ethos, but this time I'm putting it up for sale to raise funds for updating my equipment. Comes with the original box and manual. Please refer to the images for the condition. Sound output has been confirmed.
