HI CAN YOU PLEASE TELL ME WHY MY FENDER RUMBLE 100 BASS AMP DISTORTS AT LOW VOLUME? EVEN THOUGH THE SPEAKERS IS NOT BLOWN


A common reason for 'distortion' with all bass amps can be either that the screws holding the speaker unit to the cabinet have worked loose or that there has been a build up of dust particles in the corrugations around the edge of the speaker cone, which rattle especially on the lower notes.
The solution is simple - remove the front grille and check the screws are tight. Use a vacuum cleaner to remove dust from the rim of the speaker cone.

Input jack is broken


VERY common problem... this is why you ALWAYS loop your cable through the handle. One trip over a guitar cable and the yank sideways destroys the jack... AND the jacks are really weak and poor to start with... Take the thing in for repair, or if you are electronically adept replace the jack yourself. MOST of these have the jack soldered to a circuit board and one often has to remove all the front knobs and the nuts holding the volume controls and move the bord back to remove and replace the jack...

Bass Guitar Keeps sound keeps cutting in and out.


There is an inconsistency in your text. You indicate that cables were swapped and problem still existed...
You said:... "i have tried using it on a different amp and still fine".

If you tried it on a different amp and it was still fine then the guitar is probably OK.

THEN your amplifier is in question as the root of your problem.

What is the amp you have? The guitar is the CB-42, but what amp do you have?

MANY intermittent problems with amplifiers are often with the input jack itself. These jacks are easily broken by tripping over a cable plugged into them.

My Fender Rumble 25 makes a terrible crackling sound when the volume is turned up over the 4 or 5 mark. I don't think the speaker is blown as the same sound comes via the headphone socket.


Here is the schematic:http://www.fender.com/support/amp_schematics/pdfs/Rumble_Bass_Schematic_-B21.pdf Check the tubes to see if one is loose in its socket. Do not attempt to repair this yourself unless you have amplifier repair experience as it is easy to get a bad or life threatening shock without the correct test gear and troubleshooting procedures.I hope this helps.

Plug in broken


you can buy a new quarter inch jack at radio shack. These have a tendency to go bad due to all the wear put on them. Buy a new on and sotter the connections on. I think you will find your problem.

Fender Rumble 100 210 pop noise then hum after strong low e note


I just fixed my bass amp with a similar problem last week: the problem is related to a loose connection on the PCB board (likely).
A bass amp is a rough place for circuitry: the low rumble and power shake a bass amp more than a guitar amp.
In my case, the power transistors needed to be re-soldered and then the grounding bolts and screws needed to be removed and cleaned because the connection was bad. Remember that when two different metals needed for an electric connection are toughing, there is the likelyhood that corrosion WILL happen.
My bass amp did basically the same thing yours did: sounded good at low volumes, but at higher volumes it would act up.
In short, there is nothing you can do (unless you are a repair person): you need to take it to a local music shop and have a tech fix the intermittant contact problem: someone who knows what they are doing should only take an hour at most.

Hope that helps!
