Guitar Amp Repair Long Island

Why is there no sound from the amp?

The best way to look into the problem is by using the elimination method;

  • Make sure the guitar amp is connected to the power mains
  • Ensure the amp is not in standby mode. Some amps need the guitar lead in the input jack to activate. Ensure this jack is connected.
  • Disconnect FX/distortion pedals from both the input jack and the FX loop. The guitar should be plugged directly into the amp.
  • Check if the battery on the guitar pickup is dead if there are any active pickups.
  • If there is no sound after these checks try connecting the guitar and the lead into a new amp.
  • Try another guitar lead if you do not have another amp nearby.
  • If there is still no sound, take the guitar amp to your guitar amp repair Long Island dealer.

How can I safely connect my amp to a speaker?

Always ensure that you use your amp with a speaker load to avoid damage to the amp. The connection should always be done using a good quality speaker lead. You should always take care to match the correct impedance when connecting your amp to its internal speaker using a head/cab configuration or combo.

How do I get rid of excessive noise or interference?

First, ensure that you are using a high quality screened guitar lead.  Next, check the guitar grounding. Electric guitars need earthing. You do this by connecting a ground wire from the guitar’s potentiometer to the bridge of the guitar. You can check if this ground wire is correctly connected by trying to mute the strings with your hand. If the noise level changes the earthing needs to be corrected. Have your guitar amp repair Long Island technician look at it.

Interference could also be coming from an external source. Sometimes the mains socket is the source of this noise. Check if this is the case by using a mains socket in another location. Other electrical equipment can also bring on interference. Try using different mains socket for different equipment to check for this problem.

A buzzing noise is sometimes caused by equipment emitting radio waves, for example, mobile phones or radio sets. Check for this and turn it off.

What speaker cabinet is the best for my amp?

Matching the correct impedance is crucial in avoiding damage to your amp. A higher power rating on the cabinet speaker will damage both the amp and the speaker cabinet. However, the speaker cabinet should be able to handle a higher power rating. This is because amps routinely produce higher peaks than their power ratings. A higher rated speaker cabinet can handle this spike without damage. A 30 Watt amplifier, for example, should be used with a 45 Watt speaker.

When using several amps and speakers at the same time, ensure that impedance matches across all the equipment.

When do valves need replacing?

Failing preamp and power amp valves is to be expected from time to time. Some indicators that they need replacing include;

  • Loss of gain in a high gain amplifier.
  • High pitched squealing and excessive noise.
  • Loss of volume on all output channels
  • The amplifier keeps blowing main fuses
  • High Tension fuses keep blowing.

Having a qualified bass amp repair Long Island technician look at the problem is the best solution as replacing valves involves delicate electrical balancing.

Do I send over the amp for repair or use a local dealer?

This is a question that you will have to sort out when considering repairs for your amplifier. Issues that come into play include;


Is your amp still covered by a warranty? If it is, you have no choice but to take it to your dealer. This is to avoid breaking the terms and conditions of the warranty which in many cases stipulate that only an authorized technician can open it up. This means sending it over if the dealer is not local.


A guitar amplifier is a bulky object.  If you have to send it over to a dealer, you will have to incur hefty courier charges.  The amp could also get damaged in transit.


It is possible to keep checking with the local dealer on the progress of the repairs. This will pressure him to finish the job on time and do quality work. You can also adequately test your amp before taking it home.
