I just ordered a Purple MC77, and I already own the 1176LN. Honestly, tracking vocals with an 1176 is always a solid choice—you really can’t go wrong. I also have a CL1B, which is another excellent option.

For pop vocals specifically, you could easily get great results with just a CL1B or an 1176. That said, I think the Purple MC77 would be fantastic for you—it’s a great-sounding unit and a better value compared to the UA 1176 reissue.

If you’re building out your chain, I’d suggest starting with the MC77. Then, once you have more budget, add an opto or vari-mu compressor after the 1176. Some people prefer the opposite order, but I personally like to tame the peaks with the 1176 first, then smooth things out with a more relaxed compressor.

I’d steer clear of the Distressor for vocal tracking. While it’s a versatile compressor and great for utility use, I don’t think it adds the kind of character or tone you’re probably after for pop vocals. I actually bought one to try myself and ended up returning it—it just didn’t do what I needed for vocal tracking.

Hope that helps!
