Outside with a Wavedrum and even with an FX pedal, a looper or recorder ..
Im having my DIY soldering solution already for a while.
Now in 2020 there is an easy and cheapo solution for non solderers.
Basics first:
The Wavedrum is powered by 9 Volt DC positive tip ,
current draw 240 mA, maybe a bit more during startup.
This cable gives you 9 Volt from any powerbank USB port,
attached plug is 5,5mm 2,1mm positive tip

THE ADAPTER
5.5.mm 2.1mm to Korg small 9 Volt input

also works for Korg Volka and ... what else Korg ???
