Small guitar amp only works at certain volume levels?



Asked by: Bryan Saller

The most obvious culprit is the volume potentiometer: It may be defective or dirty. Try applying, contact cleaning spray, or another specific product, and whipping the knob back and forth. Another less obvious reason could be the wrong type of potentiometer installed by a technician (linear instead of logarithmic).

Why is my amp not picking up my guitar?





Check if the amp or PA you are plugged into is turned on. If using a mixer, make sure it’s not muted and that all cords are plugged in all the way. Is the amp/cable working with other guitars? Always make sure your amp is working and the cables are in good working condition.

Why does my guitar amplifier keeps cutting out?

Check the plug for damage, and then carefully inspect the cord all the way back to the amp. If it cuts out and back in with no change in volume, its probably a loose connection somewhere in the signal chain. Take a close look at your cables, and wiggle the plugs and jacks.

How can I make my small amp louder?

How to Make your Amp Sound Louder

  1. Change the position.
  2. Use a booster pedal.
  3. Swap out the speakers.
  4. Add a microphone.


Why is my amp volume low?





At times the vacuum tubes can have temperature problems and that can cause you to face issues with the low volume on your amp. If you are feeling that the volume might be dropping out on your Tube amp, you will need to make sure that you are giving it appropriate rest and that will help you out.

How can you tell if an amp is bad?

Test the sound by unplugging the sound cables or colored RCA wires.

  1. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers.
  2. If the noise doesn’t stop, then you probably have a faulty amp to replace.


How can you tell if an amp is blown?

You can usually tell if it's blown because the piece in the middle is gonna be split apart if this fuse is blown it means either there's a problem back by the amplifier.

Why does my amp fade in and out?

Sounds like a faulty tube, probably preamp judging by the symptoms. Try reseating them first, and if that doesn’t work swap each preamp tube with a known good tube until the problem goes away.



Why is my guitar amplifier buzzing?

More often than not, when your amp is making a humming sound, it’s caused by dirty power, a bad ground connection, or fluorescent lighting. Below are a few things to consider when dealing with this pesky hum.

How do I fix my guitar amp from buzzing?

Quick Tips

  1. Turn up the guitar’s volume and treble controls so that the guitar signal overrides hum and noise picked up by the guitar cable and guitar amp.
  2. Ask the guitarist to move around, or rotate, to find a spot in the room where hum disappears.
  3. Flip the polarity switch on the guitar amp to the lowest-hum position.

What is amp clipping?

Clipping occurs when more power is required from an amplifier then it is able to deliver. Once the maximum amount of power supply voltage has been reached, it becomes impossible to amplify the incoming signal without compromising its form. This means that the signal is amplified but in a very distorted form.



How do I know if my audio is clipping?

You’ll know when you have severe clipping because you’ll hear it. It sounds like the audio is starting to ‘break up,’ which is light distortion. The more severe it is, the more distorted the music begins to sound until it can become unrecognizable in an ocean of noise and loudness.

What does amp clipping sound like?

When a signal is amplified past its output threshold its high points are flattened.

Will a capacitor stop my amp from clipping?

You need to turn it down you don't need to do that you're going to make your subs fail prematurely. So in order to you to help minimize clipping from an amplifier.

Do I need a capacitor for a 1000 watt amp?

Sizing Caps



The general rule is to add 1 Farad of capacitance for every 1000 watts RMS of system power. Note that it does not hurt to use more capacitance than this rule and many systems use 2 or 3 Farads per 1000 watts RMS.



Are audio capacitors worth it?

A: Not really. A cap prevents the sound from deteriorating due to under-voltage, but doesn’t actually improve the sound. It supports the amplifier by feeding it the power it needs for short bursts. So, while not improving sound quality directly, a cap does make it easier for the amp to perform its best.
