Took my BK-7 on a gig with my midi accordion for the first time yesterday at a Farmers Market in Dublin.
Myself and Denis my Sax player played a mixture of some French musette waltzes ,bossa novas, tangos, light jazz and even Acker Bilk's Stranger on the shore with strings on the RH.

I used LH for styles/backing and live reeds with no electronic sounds on RH for most of the gig.
I was very pleased, as the gig went very well. The audience/shoppers were the sort of people who like this type of music, "organic this and free range that".
I'm definitly sticking with the BK7 for some time to come
