My son has two "toy" accordions, one is a First Act the other a "Child Prodigy". Here is some first hand info. Both have seven treble buttons but how they correspond to the 10 buttons on a cajun accordion is different. the first act has buttons 3-9 (1,2,& 10 missing). The C.P. has buttons 1-7 (8,9,10 missing). The first act has buttons like a real accordion while the CP has metal flapper/button combos. they break, I JB welded his flappers many times before getting him the First Act. A screaming 3 year old can make a grown man try just about anything. "FIX MY CORDION DADDY!!!" The first act is much better IMHO. More usable buttons and he hasn't been able to break it. he plays it every day, if i've got mine he's got his. I did have to replace the thumb strap on it but only cause i broke the original w/ my adult sized thumb.
Would you buy a Ferrari for someone who has never driven a car before to practice on? The concept of the Toy Accordion is to give a beginner a cheap learning and practice tool to see if they can learn to play the Cajun Accordion. I would rather spend and lose $20 on a toy then $300 to $1000 on something that I find I can not learn to play.
Who said that you can not teach an old dog new tricks? 61 and still learning as I grow older.
