Fix A Speaker With No Sound Bass Cabinet Amp Manual For YourBass guitar amplifiers come in a variety of shapes and sizes. Make sure the bass amp is firmly plugged into a power source and the power source is turned on. Double-check the volume and tone controls on the amplifier and on the bass guitar. It is not uncommon for a knob to be turned all the way off by accident. The volume knobs and tone knobs usually have to be turned to at least one or higher for the bass amp to produce sound. A bad cable can produce scratchy, crackling sounds, intermittent sound or no so sound at all. ![]() Refer to the manual to identify the type of fuse(s) and the location of the fuse(s) in your bass amp. It may be necessary to remove a panel cover to access the fuses. If the fuse is blown, it will have a brownish, burnt appearance. Weak or bad tubes can be responsible for amplifier problems ranging from no power, a weak or muddy sound, or a distorted sound. Properly functioning tubes have a warm, orangeyellowish glow. A bluish-purple glow means that the tube is weak and underpowered. An intense, reddish glow indicates that the tube is being overpowered. If the wires are loose, disconnected or frayed, they must be re-soldered to make a firm connection. Clean the amplifier potentiometers, or pots, with contact cleaning spray. The pots on the amp need to be periodically cleaned because dirty ones can produce static-like noises and hissing noises. Spray the pots with contact spray and turn the knob back and forth to work the cleaning solution into them. A bad speaker may produce no sound at all or it may produce a distorted or muddy sound. Remove the speakers from your cabinet if its not possible to examine them without removing them, depending on the type of cabinet. Small rips or tears in speaker cones can be repaired with tape or glue. If the cone and coil have separated, the speaker must be replaced.
