音色：

1.当balance(平衡）钮，选择用前（磁铁）拾音器时，温暖，饱满，干净，满意的中高频，使无品特有的“猫叫”充分得到表现。
   while put the balance control in front,using magnetic pickup(the humbucker).
    the tone is warm,plump,clean.make the fretless bass sounds more feeling like a cat in oestrus.
2.当balance(平衡）钮，选择用后（压电）拾音器时，音色磁性十足，带有钢味，典型的箱贝斯音色。
    while put the balance control back,using the piezo pickup,the tone is full of magnetism，typical acoustic bass sounds.        
3.当balance(平衡）钮，放在中间（前后拾音器同时 ），一种很有表现力的音色，humbucker  拾音器甜甜的音色中又夹着一点野味，一丝的“嘶叫”，很有味道！
    while put the balance control in the mid position,very activale sound.the humbucker sweet sounds with a little metal voice.
the switch,makes the  humbucker two coil series or parallel) get you full tone control.
