Worked fine yesterday. Today it will not ignite. Opened adaptor. Fuse seems not blown. Ideas?
Are you getting 9V at the shiny barrel thingy? If not, you need a new supply. Contact BBSupport to see if they can get you one under warrantee. Otherwise, any 9V supply that can provide at least 300mA will work. Must be negative - tip, positive - barrel like most pedal power supplies.
Exactly what @Rob22315 said. 
Try using another 9 volt (not higher), center negative, and 300+ mA power supply. See if it works. If it does, then the issue is the power supply and we can send you a new one. If not, then email me at support@mybeatbuddy.com and we will see what to do.
Thanks. Ordered a spare. Will let you know.
