I want a small amp for my living room playing. Mostly all clean sounds with a little gain sometimes. I want some reverb and delay. I like the fact that with the THR10C,I can set my effects up via computer and then have 5 presets to choose from. The Champ 20 is relatively cheap. I don't think the 10C is still available so I would have to find one used. I don't need loud. I have a feeling the effects on the 10C would be of higher quality. Any input is welcome.
