Obviously cost is the idea behind this, but just wondering if a simple recap or power supply section would help with noise.. AND also help to eliminate a partiular minor problem i have…
Every once in a while, if I"m playing in one register (upper/lower, etc) and hit a note that's drastically in the other register, a tiny high pitch (5K maybe?) comes in, albeit at low volume, with the note and stays until i hit another note. Well, usually it goes away upon the next note, but occasionally it stays if i remain in the same register.
It's almost like the instrument is reacting to the extreme frequency change.
It doesn't apply to a particular voice, as i've tested this out with the board open and watched the voicing to see. It just happens every once in a while, and on no particular voice.
I've had random unexplainable high pitches like this be eliminated from other equipment, mostly mixers, by addressing the power supply to some capacity. Once it was a full replacement, other times just a recap.
Anyone have any thoughts on this kind of thing?
