voicelive 3 by tc helicon
While I don't use this edition of the VoiceLive 3 by TC Helicon, I do use the previous version and it is an amazing multi-effects processor for voice and guitar (in my case cello) as well as a looper. Highly recommend this piece of gear for serious loopers.
BOSS RC-300 LOoper
I used to use the Boss RC-50, but that has been discontinued. I upgraded to the RC300 and I use this looper as well as the VoiceLive3 from TC Helicon.
BOSS Acoustic Guitar Hardware (AD-10)
This is the preamp that I plug my cello into before. it goes to the VoiceLive 3 or the BOSS LoopStation. It has a great Anti-Feedback knob as well as Acoustic Resonance and an Ambience knob. It is a looper unto itself, can run off 6 AA batteries, it has a boost button, it has a good EQ, it has a compressor, it has delay, and it has a tuner. This thing is pretty awesome. It was recommended to me by Josh McClain who is an awesome cellist who you should check out.
K&M mic stand
I love this mic stand. I even made a https://www.youtube.com/watch?v=h88JoSwKK_kYouTube video about how to fix it if it breaks which is very rare. These are the best mic stands for travel. Get the telescoping boom arm below as well.
