a couple of questions: the TS100 you linked to looks great and seems to also have the option of powering via micro USB. Have you ever powered yours in this way? Also, there appears to be a TS80 model which has is powered only via USB-C. I'm very intrigued by this for portability and convenience. Also, USBC has the potential to deliver higher power levels than earlier iterations of USB which for this application seems to be a positive.
For context, I'm not looking to get into particularly difficult/complex soldering work, only the kinds of jobs associated with a bass guitar i.e. pickup & preamp wiring.
