Compact-Practice of Oct.27:  Merely 3 people gathered. Chel, Hil and Cin. Asa phoned me he must stay home to fix his home electricity network after replacing ADSL with optical cable system. Yow to be absent this week.

Chord Progression studies: Chel showed us how chord progressions occur in The-Beatles' numbers. There I've got to know I should have taken more time to see chord progression of every tune and make a plan how to play the KB in detail, according to information the note of the tune shows.

KB Amplifier: GB-30 of Rolland, old one, is a Bass Guitar amplifier. They say its speaker is not so good. I found it at the corner of our practice site. When I've started KB playing, I used this as KB amplifier. Then Andy used it for his steel guitar. I remembered Portico Hall's stage, where we could not use our Bose-Phonic system and I used YAMAHA's guitar amplifier, which gave so miserable sounds. I drew out this GB30 to use again. Tried it. Not bad. Line-out impedence from WK3700 is 3 kiloohm. Phone-out impedence is 200 ohm. I connected Line-out to the imput HIGH of GB30. The sound was good. I wonder why its sound was so uncomfortable when I used Andy's old KB (Casio 61-key).
