Tästä samasta ongelmasta olenkin jo kirjoittanut moneen ulkomaiseen forumiin niin en jaksa tätä erikseen taas suomentaa. Kysykää jos jotain jäi epäselväksi ja tosiaan nyt tarvitsen asiantuntevampaa apua. Eli siis tässä pianossa on pickupit jotka muuntavat kielten värähtelyn suoraan ääneksi jolloin saadaa suhteellisen puhdasta ääntä verrattuna tavalliseen mikitykseen... hyvänä esimerkkinä sähkökitara jossa myöskin pick-upilla muodostuu äänet.


I have bought now one of the rarest and the most compact CP pianos; CP-60M . However, this was not used for years... it was just laying in some dusty storage with terrible smell of smoke... but well, otherwise the condition is almost perfect naturally because this was not banged up with tours and traveling...

After I got it, the first thing I noticed it was of course very out of tune because of years of unuse and there is a few other things I was already expecting from old unused acoustic piano which are purely mechanical problems and can be fixed pretty easily. The power source was also missing but I managed to build up my own.

After I got the power on, first thing I noticed was unexpected disappointment because the tremolo was NOT panning stereo like in Eletric Grand models ... is it true or is it just somehow broken??? I just loved so much hearing the CP-70 and -80 models where the tremolo was so awesome stereo effect. I am wondering because still this CP-60M does have 2 audio channels like it would be stereo???

But the real problem is that the upper registers are really silent when listening the output. it seems like there would be some problems with it's pick-ups because I noticed the the difference starts exactly in same position where the third (when counting them from left to the righ) pick-up starts. I mean the last hearable note is the last one with the second pick-up and the next unhearable note is the first of in third pick-up.

However I have checked that the electricity is working on them and there is no any point where would be bad solderings. I can hear pick-ups when touching them with my hand. So what is the problem? I mean I can hear the notes but the volume difference is huge! I can barely hear those silent parts and mostly they contain just noise. And I mean there is no any parts working and parts not working, but there is the point I mentioned that the whole left side is fully working and the whole right side is barely hearable with noise. I have checked and watched and examined but there is no anything visible to notice and the strings are in correctly positioned on the pick-ups that they should work.



So I need help because I am not really expert with these things as I presume that the problem could be in electronic side.
