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.
This is essential for cellists that sing or for just about any instrumentalist that sings or wants to mic up their instrument. The above stand is the base for this item. A straight stand with no boom is pretty much good for singers that are standing only. Even singers generally like to sing into a mic with a boom arm. This one is super solid. Never slips on me.
Together the above stand and this boom fit in a carry-on size bag and that is awesome. I like to bring this to gigs even if the venue has mic stands because often times mic stands at venues are crappy quality and they are so beat up by all the bands that come use them that they're very janky sometimes. I like to just bring my own. it adds 5 pounds, but it's worth it to me!
