I had a Sledge for 2 years. Sold it recently. Fun/easy to program. The front panel is what I liked the most- very intuitive. I'll attempt to explain why I sold it: I found that I had grown tired of the "odd" audio. It was almost like a reverb effect was always on, even though there wasn't. Specifically what I'm referring to is that there was this odd "hollow sound" that began to bug me. I hadn't noticed this problem at first, and I suspect that most folks may not notice the subtlety right away either. In fact, when I first got it I had done some side by side comparisons with my other synths and had noticed nothing of the sort. But over the long-haul, I started noticing the "problem" when I'd play it for like a half hour, then immediately switch over to another instrument, like the Nord Lead 4, or PEK. At such point the jump to improved audio character with any other synth was striking. I have plenty of VA's, so the issue I'm referring to is not a digital versus analog thing, or anything like that. I also checked every cord and mixer input to make sure I was overlooking those factors. But what I found (in my opinion) was that the issue was due to the audio amplifier. Also, the output balance level between when you'd turn effects on or off was horrible. If Sledge could fix that issue, I would be able to recommend it for certain niches/interests.
