KORG KRONOS-73     Boot issues and shutting down
Tracing intermittent faults can be a nightmare, but Clive was able after considerable patience to locate overheating contacts and repaired my Kronos by changing the interconnecting wiring loom.
After thorough soak testing, the unit was returned looking like new, most impressed, not expensive and would highly recommend.

KORG PA80         Multiple issues
Clive was recommended to me by Korg UK. In this day and age of rip off merchants and cowboys it was refreshing to find someone honest and straightforward to deal with. He named a price and stuck with it. I would certainly use him again if the need ever arises.

Roland RD-300SX     Corroded PCB
I have a 15-year old much-loved Roland Stage piano and unfortunately some of the notes stopped working. Clive soon identified and fixed the problem with the circuit board, and gave the instrument a thorough clean too. Good as new! Quick turnaround and very reasonably priced - I would fully recommend him.

VOX  AC15CH     No output. Blown Op-amp and worn valves
Hi Clive,
Just to let you know, back home and have plugged it in and it sounds great. In fact it’s better. As I mentioned, from new it had always been quite muddy on the clean channel when used with my Les Paul guitars.
At the time I bought the amp I had a 2019 Gibson Les Paul ‘modern’ and with it’s super-pokey ‘Burstbucker’ pickups and  it never really sounded that inspiring through the AC15, to the point that I sold the guitar. Since then I’ve acquired a Gibson custom shop ’58 re-issue Les Paul which was better but still not something you’d want to use on the normal channel and I ended up only using it on the Top Boost channel.
This is night and day. It’s now much brighter and actually useable with the Les Paul on the normal channel, and the “Top Boost” channel is every bit good as it was before. I’m super happy with the result, so thank you very much!
I won’t hesitate to recommend you to my friends and should a re-valve be required in the future I will be in touch.

Korg Kross-88   Key Issues
CMB repairs did a great job of fixing our aging Korg Kross digital Piano. It was easy to discuss the job with Clive over the phone who clearly has many years of experience of fixing keyboards and other pieces of audio equipment. He turned the job round quickly as we had a gig coming up. Very professional service with full documentation of what had been done and 3 month warranty. Would thoroughly recommend.

Korg Kronos   Upgrade
Clive did a great job upgrading the memory and hard drive on my Korg Kronos. I dropped the instrument off and collecting it a couple of hours later. I would not hesitate to use his services again should they be required.

Vox VT100   Unit failing after short period of time
Clive was in touch with me throughout the repair process. In fact, owing to the complete debacle created by the courier. The well packed chassis was not only delivered late but damaged. Whilst being adequately packed and insured. They washed their hands of all responsibility and only offered to refund the price paid just to send it and refused any further compensation. No wonder they have now changed their name! Never, never send anything with those charlatans. Then Clive came up trumps. He constructed a wooden cage to screw to the repaired metal Vox chassis to prevent any damage returning it. It came back with UPS and as usual with this company. Arrived damage free. So, I would not hesitate in using his service again. My business, Nobles Music Ltd., was created in 1962 and possibly why it is still here today is the commitment to customer service.

Very good company to know.

Korg Krome-88   Keys rattle and general service
Clive did an excellent job of repairing my sons Korg Krome 88 keyboard. He was not the closest repair centre to us but after providing a very detailed breakdown of the work and the likely parts required from my description of symptoms I decided to go ahead. He went above and beyond in terms of service, quality of work, replacing additional parts without charging extra. The keyboard is as good as new now so we very pleased with the end result.
Korg SP-250   Damaged power PCB
Clive serviced a very old Korg keyboard which needed some repairs. This was completed in a good time frame and in a very professional manner. We were very relieved to keep the same keyboard as we had thought it might be destined for the tip. Thank you Clive.
Roland Fantom-X8   Worn rubber key contacts and faulty push buttons
It’s very hard to find somebody reliable to fix expensive keyboards like my Roland Fantom. Clive at CMB, was clearly very knowledgeable and capable of fixing any problem. He did a great job and I can happily recommend him to anyone with keyboard problems.

Korg Kronos-73   Display issue. Wavestation EX   High pitched whistle.  Behringer XR18  Faulty channel.
I was initially referred to Clive when I took an out of warranty Kronos to Korg UK to have a new screen fitted. Clive obtained the parts and completed the repair quickly, as he was aware I needed it back fairly urgently. It was also returned having been thoroughly cleaned. Whilst in touch with Clive he also repaired a power supply fault I had on an old Wavestation, and then to really test him I asked if he would look at a Behringer XR18 mixer that had a faulty channel. Although I believe he had not had experience of Behringer equipment, Clive identified the fault and ordered the part. Unfortunately the people who let us down were the supplier themselves who took many weeks to supply the parts despite Clive’s chasing. Clive is obviously very knowledgeable and was good at explaining what needed to be done, and where necessary took pictures. It says on his website “so there is nothing I will not take a look at,” and I think I was able to put that to the test! Thanks Clive
