Some comments from you

The Deluxe sounds marvellous, and both of the Mods have done exactly what was intended. The power scaling particularly is vastly superior to other forms of attenuation. Out last night and switched to the second reduction setting and kept all the dynamics; marvellous.

Hi Dennis, The pedal is great ! Great range of tones. And I appreciate the quality and attention to detail in the construction: for example the detente, and the fact that the knobs have set-screws and are not just push-on. I was also delighted to find that you'd signed it to me when I looked in at the battery compartment! , A M Edinburgh Sep 2011

Hi Dennis,  The valves came today and the wee orange terror is sounding great. Thanks for your help the other day in getting the Marshall back in business. The work and support we have had from you has been top notch. Thanks again. Paul Murray, Aberdeenshire July 2011.

Dennis, You did an excellent job on the Fender twin. It sounds fabulous! Thank you. John Hall Dumfriesshire Jun 2011

A quick note to say thanks again for the work on the Ampeg. The combination of 2 Marshalls and the Ampeg on Saturday night was fairly mind blowing, it sounded absolutely huge and I don't think I've ever been so satisfied with my bass sound. It sounds superb through the new Aguilar cabinet aswell! We had a great show and there will be more to come...

Just a small note to let you know how happy I am with the service and the mods you carried out on my little 1986 JCM 800 Combo a couple of weeks ago.

 It is now a wonderful sounding amp that can finally give me the tones I've been chasing for many many years. The 25 year old amp was in pretty poor shape when I took it down to you and you've done wonders with it. I've had many high end amplifiers over the years (JCM's, Jubilees, JVM's, Blackstars etc.) but this little old combo now beats any of them - amazing! I will definitely be recommending you to anyone who needs a good amp tech they can trust!

I mentioned the purpose of my call was to thank you for the excellent job you did to the repair of my Boogie MK4. 

I had initially given it up for dead as it had already been inspected and returned un-repaired by two other amp/ valve specialists. 
After being recommended by Boogie UK office to contact you, within the week, you had received, repaired and shipped the amp back to me in full working condition.
On extensive testing over the last few months, I am very pleased to report that not only has the amp been fully repaired without any problems, but it seems to sound better than ever. The clean tones are stunning, lead saturation sings and the crunch settings for rhythm are perfect.
I cannot help that smile of satisfaction that comes as a result of hearing the superb tone of the amp. Thank you Dennis, an excellent job done for a very reasonable fee and good support throughout and after the repair. Can't do any better than that!        Jonathan Rumbold Ipswich Jan 2011

Just to let you know, my amp is sounding absolutely spot on!  Sounds like a completely different amp and that's in a good way.  Played through it pretty much every day since I got it back and I've got it set exactly how I wanted it to sound, gigged it on Friday past and it sounded perfect there too, thanks for making that happen!

I just wanted to say a great thank you for the pedal - it sounds great and no more tone suck when bypassed. Andy from Edinburgh May 2010 - MXR Phase 90 true bypass mod

Hi Dennis, Just a quick note to thank you for the fantastic service you provided. When a local repair guy who had 40 years experience with valve amps told me that he couldn't repair my Nomad 45 I thought it was probably terminal. However, after being advised by Westside to speak to you about the issues, my fears were allayed. You virtually diagnosed the problem over the phone and gave an accurate estimate of the cost. After receiving the amp you had it working within hours and ready to ship back to me the same day, and I can honestly say it sounds better now than it did brand new out of the box. In fact, it sounded so good, that I rang you for some advice on problems I was having with a dual rectifier that I wasn't aware of before, and the support and advise you gave enabled me to resolve the issues. So again, I would like to thank you for your time, expertise and the great service you provide which is pretty rare these days. Thanks. Geoff Healey (Wales) March 2010

"Last night's show was a blinding success and Andy is really chuffed with the way his amp is sounding. So thanks again for all you hard work. Davis" (Ocean Colour Scene backline Edinburgh Feb 2010).

Dennis, I got my Fender twin home last night.  It sounds BRILLIANT!  My  Guild X175 sounds better than it has done for years  and no feedback.  My Stratocaster sounded just fantastic.  There is hardly any noise of any description from the amp.  I have been putting up with a really sick amp for years - wish that I had sent it to you earlier! You have done a marvellous job and I’ll be playing my electric guitars a lot more as a result. I hope I get the chance to come down and meet you sometime. David Walker  Aberdeen Jan 2010

"I first went to Dennis' workshop 3 or 4 years ago after I heard the band "Avast!" playing in Dundee. Andy the guitarist had probably the clearest and most articulate rock sound coming from his Marshall JMP head that I had ever heard. Of course Andy's great playing helped but he told me about Dennis and how he had tuned his amp to perfection. I had two old JMP heads so I took them along for repair. They needed a bit of attention but I now have that great solid beefy Marshall growl but with good clean power available also. He's fixed lot's more of my amps since, from a weird WEM powercat to an old Leslie cabinet. The thing about Dennis is that he has a broad and deep technical knowledge and he combines it with his musicality so he can tune your amps to your taste. Gregor Philp". Dundee Dec 2009

    Just to say thank you very much for your hospitality yesterday, the guys were very impressed, you have 2 more fans. They were very interested in your advice about the strings & the other technical stuff, talked about it all the way home. It was good of you to take an interest. John Wood. Fife 2009

Hi Dennis, I rehearsed tonight with the new improved Fender CVR and I'm blown away. Tone tone tone!!!! It's fantastic and I believe I've been missing out all the time I've owned it as it's never sounded so warm and full. I hit a low E string and it sounded like a grand piano. Soloing with my modded Blues Driver was incredible. I really enjoyed coming to your workshop today and will definitely spread the word. Thanks again, Chris McSweeney, Dundee 2009
