Repair Terms

I charge a £15 diagnosis fee and quote you a price for the repair so if you decide not to go ahead (or fix it yourself or somewhere else), that is all you will pay.
For a diagnosis and a repair I normally charge £40 for up to one hours labour then £15 per half hour after that. The minimum cost for a successful diagnosis and repair is then £40.

Common Services

Guitar amplifier repairs and modificationsIMG_1397

I can repair most makes and models of guitar and keyboard amplifiers of both the solid state (transistor) and thermionic valve variety.

If you have found details of a particular mod on the net that you would like to have done, just email me some links and I’ll see what I can do.

Valve (tube) testing, replacement and biasing

Loss of power, slow warm up, valve rattle and crackles and pops are all possible possible symptoms of tired valves. A well gigged amp can easily wear out tubes in 6 months. Book it in for a valve test now.

Guitar effects pedal repairs

It is usually the foot switches that go on these and they can be replaced quite cheaply.

Mixing Desk Servicing

IMG_1509I have worked on Soundcraft, Allen & Heath, Yamaha, Dynacord, Studiomaster, Behringer and other makes of mixer. Common faults are scratchy and broken faders, dead channels and power supply faults. I have done a lot of work on the Dynacord Powermate series of portable powered desks that seem to be so popular with pub circuit singers and musicians.

PA power amp repair

Some PA rack mount amps can be fixed economically, depends what’s gone and make/model.

Audio cable fabrication and repair

From re-soldering a headphone jack to making up custom multiway cables. Call me for a competitive quote.

Speaker testing and replacement

IMG_1527If your cab isn’t sounding as good as it used to, you may have a damaged driver or faulty wiring. Bring it in for a quick diagnosis.

PAT safety testing

Get your amps (especially vintage ones) safety tested if you don’t want to risk going to rock heaven in the footsteps of Keith Relf of the Yardbirds. He sadly died from electrocution while playing through an badly earthed guitar amp. Valve amps can use HT supplies in excess of 500 Volts DC which is more than enough to stop your heart! A lot of venues ask to see proof of PAT testing before they let you play. A PAT test on a guitar amp, mains cable and multiway extension including a certificate would only cost you £10 and it may save your life.
