Review: Bluetone Shadows Jr.

Following in the wake of their very popular Shadows Reverb combo, Finnish boutique makers Bluetone Amps have recently introduced a smaller sibling, called the Shadows Jr.

The Bluetone Shadows Jr. (combo starting at around 1,300 €) is a hand-built, all-valve guitar combo, whose sound is based on the classic Vox AC15. Instead of being a straight, slavish copy, though, the Shadows Jr. incorporates many of the up-to-date features that have made Bluetone such a well-regarded boutique maker.

****

The Shadows Jr. has the clean and business-like looks that active players truly appreciate. You don’t want to be slowed down on stage by a control panel that’s hard to decipher. The Bluetone is clarity itself.

This is a single-channel all-valve combo running in Class AB mode giving you maximum output power at just over 10 watts.

The Shadows Jr. is designed around a trio of 12AX7 preamp tubes and a pair of EL84s powering the speaker. The combo’s power valves are cathode-biased, which means that swapping tubes won’t necessitate a trip to your friendly amp technician.

Bluetone is one of the very few amp makers who use torroidal power transformers. These doughnut-shaped devices (the black thing in the upper left corner) are lighter and more dependable than traditional transformer designs, and they offer more exact tolerances. As a valve amp is highly dependable on a stable and electronically quiet power supply for superior tone, Bluetone decided on using torroidal transformers early on, and they’ve never looked back.

The Warehouse Guitar Speakers Green Beret is an excellent choice for a strongly Brit-flavoured combo. Bluetone break in all of the speakers they use with low-frequency sine waves.

Despite being a compact single-channel combo amp (weighing only around 10 kg), the Bluetone Shadows Jr. offers an amazing amount of different clean and gain tones, thanks in no small part to the amp’s PPIMV master volume and the three-step OPC-switch.

PPIMV stands for ”post-power inverter master volume”, which is the preferred way of master volume design at Bluetone Amps, because it eats up the least amount of an amplifier’s tone, when in use. And if you turn the master volume knob all the way up, a PPIMV design makes the master volume ”disappear” electronically, making it completely transparent.

OPC, on the other hand, stands for ”output power control”. On the Shadows Jr. you have a choice of three settings, giving you 0.2, two or the full 10 watts of power, respectively. The magic of the OPC circuit is that it will turn volume levels down very noticeably without changing the tonal character of your settings, while also leaving almost all of the dynamics intact. Many lesser output power designs will turn a clean setting into an overdriven sound when you select a lower output level. The Shadows Jr. will sound almost the same on ten, two or 0.2 watts – the small tonal differences are the result of the speaker being driven differently. With the OPC at the lowest setting you will get approximately 95 percent of the full ”Shadows Jr. experience” at bedroom/apartment block volume levels. That’s fantastic!

The back panel gives you a choice of using the internal speaker or an external 4- or 8-ohm cabinet.

Bluetone have also included their tasty buffered, switchable effects loop with a dedicated volume control. When the loop is not in use, the circuit can also serve as a handy lead boost.

****

Are you looking for a cool little tone machine with a strong Vox-y flavour, and no-compromise build quality? You should do yourself a favour and try the Bluetone Shadows Jr.

The Shadows Jr. ticks all the right boxes:

You get that classic clean tone with that sweet mid-range ”attitude”. A clean tone that is lively, but never glassy or brittle.

With the front-end volume near the other extreme you’ll get overdrive and distortion that is more gritty and dynamic – think later era Beatles, windmilling Townshend, or multilayered May – than creamy and compressed.

But don’t forget to check out the wide scope of break-up Blues and Rock ’n’ Roll sounds to be had between 11 and 2 o’clock on the volume (gain) control (depending on the guitar used). You’re in for hours of wailing soloing and chunky rhythms without ever needing an overdrive stompbox.

Here’s a Gibson Les Paul Junior on its own:

Demo track number one features two rhythm guitar tracks – a Fender Stratocaster (stereo left) and a Gibson Les Paul Junior (right) – as well as a Hamer USA Studio Custom on lead duty:

The second demo track features a Gibson Les Paul Junior (rhythm left), an Epiphone Casino (rhythm right), and a Fender Telecaster (lead guitar):

****

The Bluetone Shadows Jr. is a fantastic little tone machine for the Vox-inclined player, who likes warm clean tones, dynamic break-up sounds, and gritty late-Sixties/early-Seventies dirt.

The build quality is miles ahead of any mass-produced guitar amplifier – this is a handcrafted boutique-grade valve amp. Modern additions like the PPIMV master volume, the OPC circuit, and the switchable effects loop, also raise this amp above any vintage-style copies.

For many the crucial question with low-wattage amps is volume. How loud is the Bluetone Shadows Jr?

Let’s just say that if you’ve only ever tried 10-watt tranny combos before you’re in for quite a surprise! These are ten (-plus) watts of British-style valve amp majesty, with every last ounce of loudness wrung out of the power amp and speaker.

With the OPC and the master on full, this little chap will easily get you into trouble with your neighbours in your block of flats on clean tones alone. If you don’t need 100 percent clean tones, the Shadows Jr. will easily get you through many rehearsals and gigs in small venues. And there’s always the option to stick a mic in front of the speaker.

So, don’t expect a Heavy Metal-type volume onslaught, but be prepared for some serious business.

Review: Brunetti SingleMan 16

brunetti-singleman-16-logo-2

Brunetti Amplification is an amp maker from the town of Modena in northern Italy.

Marco Brunetti’s team handcrafts a number of tasty and stylish guitar amps and effect pedals. In addition to custom orders Brunetti also manufactures a range of standard models, of which the SingleMan 16 is the smallest combo amp.

Brunetti-products are distributed in Finland by NordSound.

****

brunetti-singleman-16-front-straight

The main aim behind the Brunetti SingleMan 16 (1,348 €) is to come up with a compact, single-channel design that nevertheless offers a maximum of tonal flexibility for the working musician.

brunetti-singleman-16-front-angle-2

The elegant two-tone finish and the combo’s clear lines make the SingleMan a real looker.

brunetti-singleman-16-full-back

The combo weighs in at a moderate 20 kilos. Its open-backed cabinet is made of high-quality plywood.

brunetti-singleman-16-speaker-and-valves

The Brunetti comes loaded with Celestion’s famous 12-inch Vintage 30, which is known for its precise and multifaceted sound.

The SingleMan 16 is a genuine Class A valve amplifier. The preamp uses a pair of 12AX7 tubes, while the power amp is fuelled by two 6V6GTs.

The amp’s spring reverb unit comes from Accutronics. An on/off-footswitch for the reverb effect comes with the combo.

brunetti-singleman-16-electronics

The amp chassis is precision cut (by laser) from solid steel.

Taking a look inside, we’re greeted by top-drawer components and very crisp workmanship. In contrast to many large-volume manufacturers, Brunetti’s electronics are handwired, and soldered by real people, not robots.

brunetti-singleman-16-back-panel

The SingleMan 16’s back panel offers you jacks for external speakers, the reverb footswitch, and an effects loop (with a dedicated on/off-switch).

****

brunetti-singleman-16-control-panel

The tonal flexibility of Brunetti’s SingleMan 16 combo mainly comes courtesy of the amp’s six modes.

Three modes are provided in the preamp section (by a sturdy mini-toggle), called Tweed, Fat and Smooth. Tweed is the most angular of the three, offering up dry and very dynamic guitar tones. Fat conjures up a warmer, distinctly British palette of sounds. The third mode, Smooth, turns the SingleMan into a bonafide ”cream machine” that’s warm and a bit saggy. Depending on your chosen guitar, Smooth’s richness can be a bit of a mixed blessing. Dark sounding humbuckers might turn into a bit of a mush, here, but spiky single coils will surely benefit from this mode’s innate fatness.

Here’s a clip of the SingleMan 16’s preamp modes when played with a Fender Telecaster (’62 Custom Reissue). The guitar is plugged into the Hi-input, the Volume control is turned to 10 o’clock:

Here’s a similar clip featuring an Epiphone Les Paul Standard (with vintage-style EMG-HZ pickups). Right at the beginning of the clip I turn the Bright-switch from ”off” to ”on”. The guitar is plugged into Lo, with the Volume control still at 10 o’clock:

****

Brunetti’s SingleMan 16 also comes with three power amp modes, which see the power amp running at Full, Moderate (25%) or Quiet (6.25%) levels. Because the output power reduction is achieved by changing the internal voltages in the output valves, switching from one mode to another also has a direct bearing on the combo’s sound and dynamic behaviour. Compared to Full mode, Quiet mode is far fatter-sounding, far more compressed, and seasoned with a good helping of creamy power amp distortion.

Here’s a clip of the three power amp modes, when using a Fender Tele (Volume at two o’clock):

And here’s a similar clip with the Epiphone Les Paul (Volume at one o’clock):

****

The demo track features two rhythm guitars – a Fender Stratocaster (left channel) and a Gibson Les Paul Junior (right channel). The lead track was played on an Epiphone Les Paul Standard:

****

brunetti-singleman-16-front-angle-1

Brunetti’s SingleMan 16 is a fantastic-sounding and surprisingly versatile single-channel tube combo from Italy. It’s practically impossible to dial in a genuinely ”bad” sound, and the combo’s versatility – both tonally, as well as in terms of its output levels – means that the SingleMan 16 will feel equally at home on stage, in the studio, and in your living-room. For extreme clean headroom or bone-crushing amp stack sound pressure, you should probably look elsewhere, but I’m pretty sure most guitarists will find ”their” sound easily using the SingleMan 16.

Testipenkissä: Brunetti SingleMan 16

brunetti-singleman-16-logo-2

Brunetti Amplification on maineikas vahvistinpaja Pohjois-Italian Modenasta.

Marco Brunettin tiimi valmistaa käsityönä laadukkaita ja tyylikkäitä kitaravahvistimia sekä efektipedaaleja. Custom-töiden lisäksi Brunettin valikoimasta löytyy myös useita omia vahvistinmalleja, joista SingleMan 16 on teholtaan pienin kombo.

Brunettin tuotteita tuo maahan Pohjanmaalainen yritys NordSound.

****

brunetti-singleman-16-front-straight

Perusidea Brunetti SingleMan 16:ta (1.348 €) suunniteltaessa pääasiallinen tavoite oli toteuttaa mahdollisimman monipuolinen ja hyväsoundinen yksikanavainen kombo kätevässä ja kevyessä formaatissa.

brunetti-singleman-16-front-angle-2

Kaksivärinen viimeistely ja SingleManin selkeät linjat tekevät kombosta erittäin tyylikkään.

brunetti-singleman-16-full-back

Kombo painaa 20 kiloa, ja sen kotelo on tehty laadukkaasta vanerista.

brunetti-singleman-16-speaker-and-valves

Kaiuttimeksi on valittu Celestionin maineikas 12-tuumainen Vintage 30, joka tunnetaan tarkasta ja kolmiulotteisesta soundistaan.

Brunetti SingleMan 16 on aito A-luokan täysputkivahvistin. Etuaste pohjautuu kahteen 12AX7-putkeen, ja pääte on rakennettu kahden 6V6GT-putken ympärille.

Kombon pohjaan on asennettu laadukas Accutronics-jousikaiku, jonka voi kytkeä päälle tai pois myyntipakettiin sisältyvällä jalkakytkimellä.

brunetti-singleman-16-electronics

Vahvistinkotelo on leikattu laserilla ruostamattomasta teräksestä.

Kotelon uumenista löytyy kauttaaltaan erittäin laadukkaita komponentteja, ja työnjälki on esimerkillisen siistiä. Toisin kuin monien muiden vahvistinvalmistajien tehtaissa, Brunettin elektroniikka juotetaan käsin, eikä robotin avulla.

brunetti-singleman-16-back-panel

SingleMan 16 -kombon takapaneelista löytyy liittimet lisäkaiuttimelle, kaikukytkimelle, sekä efektilenkki omalla päälle/pois-minikytkimellä.

****

brunetti-singleman-16-control-panel

Brunetti SingleMan 16:n monipuolisen soundin mahdollistavat kombon tarjoamat kuusi toimintamoodia.

Etuasteen jämäkkä pikkukytkin tarjoaa kolme moodia – Tweed, Fat ja Smooth – joiden toiminta ulottuu pelkkiä EQ-käyriä syvemmälle. Tweed on moodeista kulmikkain ja kuivin, ja se tarjoaa hyvin laajan dynamiikka-alueen. Fat vie SingleManin soundia lämpimämpään suuntaan, joka on luonteeltaan selvästi brittihenkisempi. Smooth-moodi taas tarjoaa erikoisannoksen kermaa ja muhkeutta. Riippuu käytetystä kitaramallista, onko Smoothin kermaisuudesta hyötyä vai meneekö se jopa liian pitkälle. Yksikelaisilla mikrofoneilla Smooth kuulostaa taivaalliselta, mutta paksunsoundisella kaulahumbuckerilla soundi voi muuttua hieman puuroiseksi.

Tällaisilta Brunettin etuvahvistinmoodit kuulostavat Fender Telecasterilla (’62 Custom Reissue). Kitara on liitetty Hi-tuloon ja Volume-säädin on kello kymmenessä:

Tässä samantyyppinen pätkä Epiphone Les Paul Standardilla soitettuna (kitarassa vintage-tyyliset EMG-HZ-mikit). Pätkän alussa laitan Bright-kytkimen päälle. Kitara on liitetty Lo-tuloon ja Volume on kello kymmennessä:

****

Brunetti SingleMan 16 -kombon päätteellä on kolme eri tehomoodia. Tarjolla on Full, Moderate (25%) ja Quiet (6,25%). Koska tehon rajoitus on toteutettu laskemalla kombon pääteputkien sisäisiä sähköjännitteitä, muuttuu moodivaihdon seurauksena myös SingleManin dynamiikka ja soundi. Quiet-moodissa soundi on Full-moodiin verrattuna selvästi paksumpi, runsaalla kompressiolla ja kermaisella säröllä höystettynä.

Tässä on päätemoodien esittelypätkä Fender Telellä soitettuna (Volume kello kaksi):

Ja sama Epiphone Les Paulilla (Volume kello yksi):

****

Demobiisissä on kaksi komppikitaraa – Fender Stratocaster (vasen kanava) ja Gibson Les Paul Junior (oikea kanava). Soolo-osuudet on soitettu Epiphone Les Paul Standardilla:

****

brunetti-singleman-16-front-angle-1

Italialainen Brunetti SingleMan 16 on erittäin maukas ja monipuolinen tapaus yksikanavaiseksi komboksi. Se kattaa yllättävän laajan skaalan erialisia laatusoundeja, ja päätteen toimintamoodien ansiosta kombo sopii käytettäväksi kaikkialla, olohuoneesta studion kautta klubilavoille. Jos on suuritehoista stäkkiä vailla tai tarvitsee vahvistimeltaan ehdottomasti paljon puhdasta headroomia, SingleMan 16 ei ehkä ole paras vaihtoehto, mutta muille sillä on kosolti annettavaa.
