I went to the London Bass Guitar Show this year and I have to say this distortion pedal absolutely blew me away! It's geared towards metal bass players primarily as it uses the same principal as the likes of the dUg pedal and DG X series by splitting highs and lows and distorting the upper frequencies while keeping clean and compressing/limiting the lows. I have to say it was far more intuitive to use and get a massive tone from than the other pedals mentioned. The owner/designer was on the stand and very knowledgeable and enthusiastic, explaining that he comes from a recording background. He's basically put the tried and tested processing used in metal bass recording into a very easy to use package. I thought I'd share my experience of this pedal in case TB'ers are interested in keeping an eye out for it. Unfortunately it sounds like it isn't out for a while as it's a bit of a start-up company. If they are at any trade shows or exhibitions go check them out in the meantime. There doesn't seem to be a great deal on their website yet - Landing page - TRONDHEIM AUDIO DEVICES AS but I believe there are a few vids on YouTube that give examples of what it sounds like. Massively impressed and can't wait for the release!
As far as I know, they've been handing out some of the preorder units, like mine. I don't think it's available over the counter yet due to production limitations but things are happening
If I remember rightly from talking to the designer, the Mid control is in fact a crossover frequency control rather than a traditional Mid gain. I think I remember him saying that the top end distortion crossover is fixed, and this controls the LPF on the clean, compressed low end part. Unlike other crossover based distortions this creates a gap in the mid frequencies, the size of which is controlled by this 'mid' control, giving the apparent effect of a mid boost and cut. It was a little while ago now so I may have got the details mixed up there, but I think that was the gist of it.
I like it a lot, I almost don't feel I need anything else for the kind of music I'm playing, which is mostly metal. I've gone to just this and a Boss GEB-7 for minor tweaks only. It's very responsive, you can easily hear the sound change when turning the knobs and it tightens the sound a lot somehow if that made sense haha. As for the internal specifics, I am not sure if it's set or not but I know that the mid control is different from a +/- xdb at xhz so I guess you might be right I like that you can turn on/off only the drive by engaging/disengaging the pedal, there's no bypass or anything.
