Repairs Pricing

For repairs I charge by the hour.  £30 per hour in 15 minute chunks based on a no fix – no fee basis.

I know that some people may find the idea of an hourly rate off-putting when it comes to repairs.  But don’t worry I act fairly; look.

  • So if I a repair jobs starts to take longer than discussed originally then I will have called you to discuss how to proceed. You will never get a shocking bill
  • and if I have to spend a lot of time figuring stuff out for your amp, then that is my problem and not yours – I get the experience but I don’t pass that cost on to you. 
  • Bottom line: I only charge for what I have done to your amp that you will get benefit from.

I have written guide lines in what I can achieve in various time frames just to help set the clients expectation really.  Take a look through and see if you can find your fault!

30 minute jobs
What can be achieved in half an hour is kind of limited to jobs that don't require removing the amplifier chassis from the cabinet.
Bias Check and Adjust Some amps have an easy to access bias measurement point e.g. Marshall like JCM900 onwards, most open back combos with down hanging tubes allow the connection of a bias probe
Simple Part Replacement Covering easy access components like footswitches, fuse replacement, simple soldering jobs etc
Cabinet Repairs Feet, Jack Sockets, Handles
60 minute ball park
Tasks where no fault diagnosis is required since the faulty part is apparent; typically can be done in an hour.
Damagded Part Replacement Involving no, or very little fault diagnosis e.g. jack sockets, control potentiometers (pots), switches, cables, reverb tanks.
90 minutes zone
Significant faults but clearly just one problem
Reverb Problem Usually faulty tank, leads or drive circuitry (valve or op amp typically)
Volume cutting out recognise this? Volume fine, then low – almost strangled, then bang the top and it's fine. Or loud pops when tapped. Try the amp later and it's fine. Go to gig or rehearsal and it lets you down. Usually bad connections in the amp probably one of the biggest problems I deal with. Repair is reliable if solved thoroughly and with the right kind of voodoo.
Distorted Sound guitar sound like a robot or metallic sound like a mobile phone too near the amp. Faulty valves or op-amps
Noise Whistling, Rustling like the rumble of old vinyl, Hiss, Buzz and Hum – or a combination of those. All familiar sounds with a variety of causes (faulty pre amp tubes, bad connections, leaky caps, failed filter caps) and sometimes just a characteristic of the amp's design or construction.
Transformer replacement Usually takes a couple of hours especially if there is metalwork adjustments required.
two hours zone
Diagnosing faults takes time. I reckon I can solve most faults in two hours but often a single problem to the musician is technically a few problem in the amp, so this is where the guide starts breaking down. I'll try and give a few examples of faults, and there cause
Dead Amp No lights or some lights but no sound. Lots of causes – please don't replace fuse with a bigger one
Burning smells Turn it off and get in touch – you will stop further damage
