Undertaking A Guitar Amp Repair

By Donald Wilson


Both solid state and vacuum tube amplifiers will require regular checkups and occasionally a fault repaired. Most guitarists will at some point need a guitar amp repair. A few points should be taken into account before opting to have the work carried out.

The other type is a combo with the speaker built into the cabinet; these are more common for home use due to the size and affordability.

Most musicians will keep spare valves with them, especially if performing regularly and it is important that the correct tubes are used. When servicing or fixing a tube model it is advisable to have an expert carry out the work due to the voltages involved.

Using these factory components ensures that the value is not affected and that they will be of the correct spec. Many manufacturers and registered dealers will still stock items for older models and these should be used when available. The factory is also the better choice for carrying out the work due to their specialist knowledge.

After ensuring that the correct replacement items have been sourced and the appropriate tools are available to be used, the repairs can be done.
