CE-2B отличается в звуковом тракте от CE-2 емкостью конденсатора С14 (она меньше, чем у CE-2) и наличием гасящего задержанный сигнал потенциометра Level. И все!
Все одно и то же, даже сервис мануал на них один.
Просто у меня есть СE-2, японский, поэтому и продаю.
Разницы в звучании у них практически нет, в отличие от цены!
CE-2/CE-2B differences
The CE-2B circuit is almost identical to the CE-2 with only a few differences. The most obvious change is the additional 250kΩ E.Level potentiometer inserted in series with R22 (47kΩ). Also, a component of the high-pass filter, the C14 capacitor, located just before the mix control, is changed from 0.033uF to 0.012uF. A CE-2B with the E.Level knob turned fully clockwise will sound almost like the CE-2, but with the chorus effect applied to slightly higher frequencies.
Transforming a CE-2B into a CE-2 is simple. First, change C14 (0.033uF) to 0.012uF. The level knob acts as a short if set to the max., so the removal is not necessary, just remember to always keep it turned fully clockwise.
If you want to completely eliminate the function of the level knob, short all its 3 pins together. Alternatively, you can remove the wires that go to it and solder the 47k (yellow, violet, orange, gold) resistor directly in the board.
There are other component changes you could make, but they will not affect the quality of the sound.
