We repair all types of musical instrument amplifiers, effects pedals, and pro audio gear at our workshop in North London. This includes the repair, servicing, or modification of the following types of equipment:
- Guitar amps: valve/tube, transistor/solid state and hybrids.
- Effects pedals and pedal boards.
- PA amps, active monitors/speakers and mixers.
- Pro audio preamps and outboard effects.
- Electric guitars/basses: pickup replacements and wiring mods.
Although we may be able to guess what is wrong with your equipment based on the symptoms, we can't know for sure until we look inside and take some measurements. We therefore can only give you a quote once we've inspected the equipment at our workshop. Nevertheless, we can give you some ballpark prices of some typical jobs that we do. Note that your equipment may have more serious faults than those described below, in which case we will give you a custom quote before we proceed so that you are fully aware of how much your repair will cost before committing to it.
A guitar amp service starts at £60 labour + parts (inc VAT) and includes cleaning of pots and connectors, inspection and repair of solder joints, replacement of faulty valves, and biasing of the output stage (if necessary). Standard production valves are usually around £14 per preamp valve and £21 per output valve (inc VAT), but they can be considerably higher if you want specific NOS valves.
A full service (as above) and a recap - i.e. replacement of old electrolytic capacitors which is typically necessary in vintage amps - starts at £125 labour + parts (inc VAT). An amp like a Fender '57 Tweed Deluxe has 3 large and 3 small electrolytics. A good quality replacement set for such an amp would cost £25 (inc VAT).
Here's an example of a repair job on a guitar amp. This amp had a faulty relay. A repair like this would cost £65 (inc VAT) including the replacement part.
A pickup replacement starts at £50 labour + parts (inc VAT). The cost of a wiring mod such as coil taps or custom switching arrangements costs the same as a pickup replacement.
A treble bleed mod costs £30 (inc VAT).
