It will sound like </FONT> <DIV><FONT size=+0>a piano version of a solid-body electric guitar without an amp. However, </FONT></DIV> <DIV><FONT size=+0>even though it would be nicer to have an amp, I have tuned a couple CP-70s </FONT></DIV> <DIV><FONT size=+0>without an amp - its doable. The lack of amplifier is less a challenge than </FONT></DIV> <DIV><FONT size=+0>the scale."</FONT></DIV> <DIV><FONT size=3></FONT> </DIV> <DIV><FONT size=3>Yes, they do need an amplifier, IF you are not using an ETD. However, be aware that an amplifier adds another layer of EQ annomolies that I choose not to want to contend with. If you have to use an amplifier, set all the settings on "flat". Tis' better to add a good microphone, if the ETD can't "hear" the strings adequately, IMO.</FONT></DIV> <DIV><FONT size=3>As for the "scale", I've evaluated them and have found that the Scale is actually well thought out and predictable. They are just different, in regards to what we normally have trained ourselves to "listen" to, in the tuning process. It is far better to tune these with an ETD, IMO.</FONT></DIV> <DIV><FONT size=3>I agree with you, Terry, they are really "cool" and I wish that Yamaha had continued with this technology. Ah, the possibilities....endless, IMO.</FONT></DIV></DIV> <DIV>Regards,</DIV> <DIV> </DIV> <DIV>Joseph Garrett, R.P.T.</DIV> <DIV>Captain, Tool Police</DIV> <DIV>Squares R I</DIV> <DIV> </DIV> <P></P></BODY></HTML>
