Richard recommended this to be fitted to an Auden Chester I was purchasing from him, and it's great. Honestly, it's not going to worry a mic for tone, but as an undersaddle system and at a much keener price point than a good mic or blended pickup, I wouldn't expect it to, it's unfussy and straightforward so it's perfect for my needs right now. Unintrusive (soundhole controls), and a good range of output level with the onboard volume control, sounds great just plugged straight into a desk which is again absolutely what I need. The tone wheel takes a little getting used to, coming as I do from the 3 band EQ side-mounted controls brigade, as it's a single wheel. It's not the most radical tone pot ever, but it is very good at capturing the sound of the guitar and allowing you to adjust to the room you're playing. I like it a lot!
