I've had the 1973 for about 2 years now and it's finally found it's proper home. I am so very happy with it that I am actively trying to find a second one... though I doubt I'll actually buy a second one, you never know. It took me a while to get used to MB compression with no control over ratio. Read more
I'm a lover of lower than 2:1, which is this unit, and so I had to use it a lot to get used to how to set a 2:1 MBC. Next, I had to get used to the fixed attack and release settings. Again, once I learned what I liked, it became a breeze.
I also had to get used to the crossover slopes, which are far more gentle than most crossovers I'm used to working with. Generally I'm used to a 12db/oct slope, but I'm pretty sure this one is a 6db/oct. That was the trickiest difference for me to get used to. It made it harder to hear the little changes, but now that I know what I'm listening for, I find it cleaner, with less smearing at the crossover points... I don't know if that's just all in my head.
Over all, I find this unit clean for a FET circuit. Which makes it far more useful on a variety of stuff, and because of that it lives on my 2buss.
Now, there is one thing that bugs me about it, and I've found I can live with it. Instead of soloing the band you want to listen to, you mute the bands you don't. I know this is a cost savings measure, and a small inconvenience for some, but I do have to dedicate a moment's thought to it before I use it.
I haven't yet found a use for the low end enhancement circuit OR the high frequency boost. Neither sound right to me, so i just don't use them at all. Which is fine.
Recall is easy enough, despite the lack of steps or detents on the threshold and gain knobs. And the blend, bypass, and metre calibration are all nice to have, too.
Super happy with this thing. Highly recommended for a solid state MBC.
