"ACCORDION!!!" was the Jono response. Makes sense, as Weird Al and John Linnell both play accordion.
I looked online and ... man, accordions are pricey! The big professional ones *start* at $1000, and the "beginner" ones start at $400. Jeez! And apparently buying via the internet is not always recommended because it's composed of a bajillion parts that might wiggle and break in shipping.
By now Jono had found youtube videos of people playing Tetris with Accordion, and the super-cool theory-friendly bass note schematic and was getting increasingly excited. Even though the right hand chromatic button system is pretty cool and easy for transposing, Jono decided he wanted a piano accordion for transferable skills.
At this point, I'd found an ebay accordion that seemed to be in my price range (~$400), but Jono's like "so sketchy!", so I looked for info about the sketchy ebay accordions, and in the process, found an accordion shoppe in Oakland! With accordions ranging from $200 to $7000. So we made plans to visit on Saturday.
The rest of the week, Jono looked up a ton of accordion youtube videos and got increasingly excited. Until finally it's Saturday, so we hustle up the Oakland to the accordion shoppe.
It's the sketchiest storefront ever: you enter through a side door and it's an enclosed room in an empty warehouse. But this dude was there and we went in and there were a ton of accordions!
Jono quickly decided on a 34 key 72 bass accordion that's like this one, except red. That plus the instruction book came out to about $790, so I paid for part of it, and Jono paid the rest. It comes with a 1-year warranty, as well as a 75% trade-in deal. (So if Jono ever wants to upgrade...)
So now we have an accordion! It's pretty cool! :D
