I love mine. If you like Markbass, then you'll like this. It's been a few years since I had a LM3, but it feels like a more powerful version of it. It's about as user friendly as they come. I don't EQ more than a notch either way of 12 o'clock, but the filters are there to quickly get 'old skool' or 'modern'.
If you're not a Markbass fan though, it's nothing new.
