6 Playing Sounds Installing Batteries * Batteries are supplied with the unit. The life of these batteries may be limited, however, since their primary purpose was to enable testing. Insert the included batteries as shown in figure, being careful to orient the batteries correctly.
7 Playing Sounds Turning on the Power Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.
8 Using the Effects When the power is turned on, the FILTER/TONE, DRIVE/SYNTH, and DELAY/MODULATION are switched off. Also, the expression pedal will function as volume pedal.
9 Using the Effects COMPRESSOR/LIMITER fig.0110 This comprises two effects, one that evens out the volume of the input signals to provide lengthy sustain (compressor), and one that prevents distortion by suppressing only the peaks in the sound (limiter).
10 Using the Effects FILTER/TONE fig.0120 Included here are eleven different effects that alter the particular characteristics of the bass sound itself. You can select and use any one of these effects at a time. FILTER/TONE pedal The filter tone is alternately switched on and off each time you press the pedal.
11 Using the Effects DEFRETTER This effect allows you to use a conventional bass to simulate a fretless bass. SENS/BOTTOM knob Adjusts the amount of defretter effect applied in response to the input sound. DEPTH/TONE knob Adjusts the tone. Turn the knob to the left for a milder sound, or to the right for a sharper sound.

14 Using the Effects DELAY/MODULATION fig.0140 This provides the delay effect, in which the sound is slightly delayed and is fed back to the direct sound, and the modulation effect, which adds a sort of swell to the sound to give it greater breadth. The ME-50B comes equipped with eleven different delay and modulation effects.
15 Using the Effects ANALOG DLY/0-400 ms DLY/300-1400 ms DLY ANALOG DLY: This gives a mild analog delay sound. The delay time can be set within the range of 100 ms to 500 ms. 0-400 ms DLY: Delay sound of 0 to 400 ms delay time. 300-1400 ms DLY: Delay sound of 300 to 1400 ms delay time.
