Vox VBM-1 Amplifier KAT Speaker Modification

Knight Audio Technologies (KAT) has developed a “drop-in” speaker upgrade for the popular, discontinued Vox VBM-1 Brian May Special amplifier. It costs £35.00 + shipping direct.

An alternative upgrade option which some people have carried out involves buying a Dai Ichi brand DC65-30 speaker (still available from Wagner Online in Australia at the time of writing) and fitting a 390 microH 1.3A ELC16B radial inductor (choke), RS part no. 6755576 and a 2.2 microF capacitor, RS part no. 7270473.

However, this original option is ultimately more expensive and involves soldering. Check out the product on the KAT website and view the straightforward installation video on Nigel’s YouTube channel.

Text from the KAT website:

“This is a brand new speaker/filter combination enabling VBM-1 users and Deacy Amplifier-style project builders to get their amps closer in tone to the real Deacy Amp.

The KAT DSP 6.5 TC has been developed primarily as a replacement for the Celestion G6 unit that is sadly no longer in production. It has an on-board filter network that tailors the frequency response to give the full-bodied mid range tones of the real Deacy but without the HF ‘fizz’ that seems to dominate most 6.5″ twin-cone drivers.

A by-product of this development was the realisation that this unit could be dropped straight into the Vox VBM-1 giving immediate results. The Vox VBM-1 is a great amplifier, but, it is a little let-down by its stock speaker unit that tends to suck-out the precious mid range tones and enhance the unwanted high frequency ‘fizz’. The KAT DSP 6.5 TC is a straight swap-out with the stock VBM-1 unit with no soldering required to undertake the works. Just 11 screws and 6 minutes will have the works completed and the tone of the amplifier improved many-fold!

The KAT DSP 6.5 TC can also be used in your own Deacy amplifier-style projects to give your amplifier that great Deacy ‘honk’!”

Brian May Red Special Replica Full Design and Build

I am pleased and relieved to report that the approximately three year labour of love to make a replica Brian May Red Special guitar is finished. I have written 60 numbered articles covering every part of the project plus four additional articles describing the design process, covering tools and tips and listing the materials, parts & suppliers. These are richly illustrated with hundreds of detailed pictures and should be of general interest to Queen and Brian May enthusiasts including anybody who is considering embarking on a similar mission. This has been like undertaking a second PhD in terms of the time and intellectual effort I expended so please check out the project pages on this website here:

Seiko 5 Sports Brian May Limited Edition

The Red Special now inspires a new Seiko 5 Sports watch whose dial echoes the design of the guitar which Brian and his father built in the early 1960s. Seiko celebrates Brian’s creativity and his music with this Seiko 5 Sports watch. Brian commented: “I am delighted to see this watch come alive, and proud that the creation of me and my dad all those years ago has inspired this collaboration. I love my Seiko and it has served me well for many years. I will wear this new one with pride.”

The dial has the same red and black color scheme as the Red Special and features a delicate wood-like pattern like the body of the guitar. Special markings on the case back. The watch is offered as a limited edition with Brian’s signature on the case back and comes with “LIMITED EDITION” and the serial number 0001/9000-9000/9000.
The presentation box also contains a commemorative coin that is based on the sixpence that Brian has used throughout his career as a plectrum.

CNC Cutting MayStar Mother-of-Pearl Inlays

I had been wanting to try some inlay work for a while, for a challenge and something different to do. I constructed the shape by overlaying arc and line segments over a zoomed high resolution image, adjusting all the positions until the spacings were symmetrical taking account of photographic parallax then finally traced over that with a polyline. Care needs to taken to get the feed rates and spindle rotational speed correct first time because this small (42 x 22 x 1.0 mm) sheet of mother-of-Pearl (nacre) cost £7.49 from Rothko and Frost. Next I need to compile the cutout toolpath for the perspex. This is not as straightforward as simply linearly scaling up the object in CAD and using it as a subtrahend to create a rebate. The entire object needs to be reconstructed from a closed polyline which has an outline that is uniformly larger by the cutter diameter.

Travel Guitars

Pictured below are the first guitar I made: a 3/4 scale Red Special which was signed by Brian May in December 2017 and Guyton RS Transporter No. 9 of 25. One of several suitable options to obtain the Brian May tone away from home is a Vox MV50 AC compact guitar amplifier head, a traditional style treble booster and a good quality set of monitor headphones. Just because… Why not? Let’s hear it for travel guitars.

This emulation software is one of the cheapest and most straightforward ways to recreate many of Brian May’s tones, especially the complex three amplifier, twin delay Brighton Rock solo. It is ideal for quiet practice when used with a suitable interface such as the iRig HD2 and monitor headphones and as a travel outfit. Renowned professional guitarist Jamie Humphries helped develop the tone patches and you can watch him demonstrate the software on this official video:

Brian May Guitars Treble Booster Classic

Made in the U.K. and engineered by Brian May’s electronics guru, Nigel Knight, this compact, multi-mode treble booster pedal combines three uniquely-voiced circuits that faithfully replicate Brian’s most recognisable tones from the 1970s, 80s and 90s. The tones representing each decade have been meticulously modelled on the actual vintage equipment used by Brian during each period of his career – his germanium transistor Dallas Rangemaster from the 1970s, the silicon BC149 transistor powered Cornish TB-83 installed on his pedal board throughout the 80s, and an original 1998 Greg Fryer strap booster.

Nigel Knight analysed every nuance of the original circuits to realise an authentic reproduction of their tonal responses and output profiles. This 3-in-1 treble booster provides amateur enthusiasts and professional guitar players alike the opportunity to select the distinctive sound of their favourite Queen era using a switch and level control based on the lathe-turned aluminium control knobs fitted to Brian’s Red Special guitar. Whether you seek to replicate the heavier Queen tracks such as Stone Cold Crazy, the live sounds of the 1986 Magic Tour or explore your own ‘New Horizons’ with Brian’s more recent works, this will be the only treble booster you will ever need. Available now from Brian May Guitars and Knight Audio Technologies:

If you aren’t already aware of Jake Lizzio’s instructional material, I recommend you check out his YouTube channel, Facebook page and website, Signals Music Studio. I have read and watched a lot of information about music theory in recent years but none comes close to Jake’s ability to make this topic accessible and fun. Check it out whether you’re a beginner or an advanced guitar player.

In the embedded video below he explains why he believes that the chord progressions in We Are The Champions (enthusiast code WATC) are perfect. I agree with him, but it’s sure nice to understand why.

Guyton RS Transporter #0817154 (No. 9 of 25)

In January 2019, I was very pleased to be able to acquire Guyton RS Transporter #0817154 (No. 9 of 25). I am the instrument’s third owner after it was originally commissioned by Craig Farley of Queen Tribute band Forever Queen. I’ve been unable to see them play live because most of the venues they play at are in the south of England. Check their pages out:

The Guyton RS Transporter was designed by Red Special community stalwart Martin Pitcher and is expertly realised by Suffolk luthier Andy Guyton. It has achieved the distinction of replacing the scalloped fretboard Guyton Red Special as Brian May’s pre-concert warm-up guitar.

In the unlikely event that you’re not already familiar with this guitar, please check out Craig’s unboxing video on YouTube where he makes a significantly better job of demonstrating it than I ever could
. The guitar is designed to be a travel variant of Brian May’s original Red Special with woods, neck dimensions, Adeson Tri-Sonic pickups, pickup spacing and controls closely reflecting those of the original instrument. It is obviously headless and makes good use of the JCustom XS tremolo bridge.
