All pre-WWII guitar amps are muddy-sounding and uninspiring pieces of junk. Right? No, wrong!

Granted, some of those old-timers are almost completely geared towards clean Jazz tones, but you might be surprised by some of the forward-thinking features many of the early guitar amplifiers include.

The brand-new Bluetone Atlantis Reverb combo (1,950 €) is a handcrafted Finnish all-valve amp, that is based on one of the most fascinating old designs, the Gibson EH-185 (c. 1940). The original Gibson combo included an active two-band tone stack, which is a feature still only found in a handful of guitar amp designs.

For Bluetone’s Harry and Lauri the ball started rolling, when a customer ordered a quasi-replica of the EH-185 from Bluetone. Intrigued by the challenge, the guys came up with a number of ways to realise the vintage circuit with modern components.

The Bluetone Atlantis Reverb takes these updated circuits, and combines them with a number of Bluetone’s modern features, to arrive at a modern and roadworthy alternative to the late-1930s original.

This is what the Atlantis Reverb looks like on the inside – super clean workmanship and top-notch components in a easy-to-service PCB layout.

The Atlantis is a single-channel guitar amp; the input section comprises controls for volume (gain) and the two-band active EQ (cut and boost), as well as a switchable preamp boost and a Bright-switch.

The effect section features an Accutronics spring reverb unit and Bluetone’s own, beautiful bias-modulated tremolo. Both effects can be switched on and off.

The output section sports a switchable Solo-boost and a post phase-inverter Master-volume control. The post phase-inverter design means that turning the Master full up takes the control out of the circuit completely.

The back panel offers additional speaker outputs, an unbalanced line-level output – with its own, built-in dummy load and level control – as well as the DIN-port for the footswitch unit.

A three-switch footswitch unit is included with the Atlantis Reverb combo, as is the necessary cable.

The Bluetone Atlantis’ preamp isn’t your run-in-the-mill 12AX7-based design, but instead runs a pair of NOS 6SL7-tubes and one 6SN7 to achieve its special tones. Both models were very popular among tube HiFi enthusiasts in the 1990s, but are extremely rarely seen in modern guitar amps.

The power amp can run most of the common octal power amp valves, such as the 6V6GT, the EL34, the 5881 or the KT66. The design is cathode-biased, which means you can drop in a new pair of tubes without the need for manual biasing. The only thing to remember is that if you want to use a pair of 6V6GTs you have to put the small switch (hidden in the picture by the back panel) to ”6V6GT” to prevent any damage to the amp. All other valves are supposed run on the 6L6GC setting.

From the workshop the Bluetone Atlantis Reverb comes equipped with a pair of 6L6GCs, giving you a Fender-style power amp with an output somewhere between 25 and 30 watts.

The black round thing in the picture’s right-hand corner is a toroidal mains transformer. The guys at Bluetone swear by toroidal mains transformers, because of their reduced weight, great reliability and superior (read: lower) hum-induction levels.

The combo’s cabinet is a traditional Fender-type open-back design. The speaker is a 12-inch Celestion Neo Creamback unit rated at 60 watts.

The cabinet is made of lightweight and ecologically sound solid paulownia wood, making the Bluetone Atlantis Reverb far lighter to carry than what you’d expect from a 12-inch speaker equipped traditional design.

• Mic: Shure 545SD
• Preamp: Universal Audio Volt 2

The Bluetone Atlantis Reverb combo’s forte definitely lies in its clean and break-up tones. The cleans have a charming chime to them that’s all their own – the sound, at least to my ears, is even sweeter than on a Fender ”Blackface” offering a lot of three-dimensional depth to your playing.

The two-band active EQ allows you to tailor the amp perfectly to any guitar you might pick, proving to be a very effective tool both on stage and in recording situations.

Overdriven sounds have their charms, too, as long as you don’t expect any creamy distortion from the Atlantis Reverb on its own. This combo’s crunch is of the late-Sixties/early-Seventies type, perfect for early-Santana, classic The Who, or T. Rex style excursions, which put dynamics and attitude front and centre.

The Atlantis also works exceedingly well with all types of effect pedals.

If you have an opportunity to test drive one of these beautiful handcrafted gems, you should definitely grab it!

Testipenkissä: Bluetone Bluesmaster – suoraan asiaan

Tässä videossa ei ole käytetty efektipedaaleja.
Alkuperäinen Musicmaster Bass 1970-luvulta oli bassolle tarkoitettu harjoitusvahvistin.

Fenderin alkuperäinen Musicmaster Bass -kombo oli mielenkiintoinen tapaus. Musicmasteria oli ajateltu alkavalle basistille sopivaksi harjoitusvahvistimeksi, ja sitä myytiin jopa paketissa samannimisen ”halpabasson” kanssa. Kombo oli kuitenkin jonkinasteinen pettymys, sillä sen soundi oli suhteellisen ponneton ja potkuton.

Viime vuosina jotkut kitaristit ovat kuitenkin alkaneet nähdä Musicmaster-komboa edulliseksi mahdollisuudeksi päästä käsiiksi aitoon Silverface-soundiin. Totta, tämä kombo on varsin riisuttu ilmestys, mutta se on kuitenkin täysputkikone. Lisäksi se ei ole keräilymalli, minkä ansiosta Musicmasterin modaaminen omaan tarpeisiin ei tunnu lainkaan pahalta ratkaisulta.

Tästä ilmiöstä meidän stoori alkaa:

Suomalainen vahvistinpaja Bluetone on hiljattain alkanut valmistaa oman käsintehdyn ja parannetun version Fender Musicmasterista. Uutukainen on tarkoitettu nimenomaan kitaristille. Uuden kombon nimi on Bluetone Bluesmaster, ja sen hinta on – valituista optioista riippuen – jossain 960 ja 1.190 euron välillä.

Bluesmasterin signaalitie on periaatteessa sama kuin alkuperäisessä styrkkarissa, mutta muutamalla parannuksilla, kuten Low Cut -bassoleikkuri ja Bluetonen oma OPC-tehosäädin. Kolmiasentoisen OPC:n (Output Power Control) ansiosta Bluesmasterin lähtötehoa pystyy pudottamaan jopa vain kahteen wattiin, ilman että kombon soundi muuttuisi ratkaisevasti.

Koska alkuperäinen Musicmaster oli tarkoitettu halpavehkeeksi, Fenderin insinöörit poistivat kaikki ylimääräiset komponentit, jotka eivät olleet välttämättömiä saada bassosignaalia vahvistetuksi kaiuttimelle. Ehkä epätavallisin ratkaisu oli toteuttaa Musicmasterin vaiheenkääntäjää muuntajalla, kun se hoidetaan yleisesti putkella.

Niin kuin näkee kuvassa (yllä) Bluetone on käyttänyt samaa ratkaisua myös uudessa Bluesmasterissa. Putkien lisäksi – yksi 12AX7-putki (etuaste), sekä kaksi 6V6GT-putkia (pääte) – siellä näkyy kolme muuntajaa. Piennemmät niistä ovat vaiheenkääntäjä ja audiomuuntaja, kun taas se isompi musta kapistus on kombon sähkönsyöttöä varten.

Kitaristien suosituin modifikaatio vanhaan Musicmasteriin on alkuperäisen Fender-kaiuttimen vaihtaminen johonkin soundilta tukevampaan.

Bluetonen Bluesmasterissa on jo valmiiksi asennettu alkuperäistä laadukkaampi ämyri. Kymmenentuumainen Warehouse Guitar Speakerin G10C/S kuuluu WGS:n American Vintage -mallistoon, ja sitä tunnetaan sen selkeästä ja lämpimästä soundista. Tämä malli tykkää myös efektipedaaleista. Bluetone tarjoaa optiona myös toisentyypistä kaiutinta Bluesmasteriin (tsekkaa Bluetonen tuotesivulta).

Takapaneeliin on asennettu virtakytkimen ja pääsulakkeen lisäksi ainoastaan kolme kaiutinlähtöä.

****

Vaikka Bluetone Bluesmaster -kombo voi vaikuttaa ensituntumalta hieman kuivakkaalta ja suorasukkaiselta, se lisää eittämättä jotain maagista lisämaustetta soundiin.

Vahvistin lisää nimittäin annoksen hienon musikaalista kompressiota jo puhtaaseen meininkiin. En puhu sellaisesta kompressiosta, joka puristaa nuottien atakkia kasaan, vaan tässä vahvistin ikäänkuin lisää nuotien häntäpäähän lisää eloa. Bluesmasterista saa näin enemmän sustainia vaikkapa puhtaaseen kantri- ja bluessoittoon, ilman että atakin napakkuus kärsisi tästä.

Koska Bluesmasterissa on kyse matalatehoisesta putkivahvarista ilman master volyymiä, kannattaa mielestäni ehdottomasti kokeilla rauhassa läpi minkätyypisiä soundeja saa aikaiseksi Volume-säätimellä, sekä vaihtamalla Low- ja High-tulojakkien välillä.

Bluetonen Bluesmaster-kombo ei tarjoa massivisiä määriä puhdasta headroomia, mutta sen sijaan siltä saa esillä todella herkullisia reunasärösoundeja, jotka reagoivat erinomaisesti soittajan dynamiikkaan ja kitaran volume-säätimeen. Kombo toimii hyvin myös efektipedaaleilla.

Volume-säätimen ”loppumetreillä” pikkukombosta lähtevät myös maukkaita särösoundeja. Huom: koska kyseessä on non-master volume kombo, Bluesmaster soi täydellä säröllä suhteellisen isolla äänellä, jopa kaksiwattisena, ja voi silloin olla liian äänekäs kerrostaloon.

Kaikki demobiisin kitararaidat on soitettu suoraan Bluetone Bluesmasteriin ilman pedaaleja. Kitararaidat äänitettiin Shure 545SD -mikrofonilla Cranborne Audio Camden -mikkivahvistimen kautta audiosekvensseriin.

• Komppikitarat: Gibson Les Paul Junior (vasen kanava), Fender Stratocaster (keskellä), Fender Telecaster (oikea kanava)

• Soolokitara: Hamer USA Studio Custom

****

Uusi Bluetone Bluesmaster lunastaa kaikken mitä se lupaa. Minun mielestäni tämä on erinomainen Silverface-tyylinen putkikone blueskitaristille. Bluesmaster on käsintehty laatuvahvistin, joka tarjoaa rutkasti parempaa työnjälkeä kuin esikuvansa, ja joka on valmiiksi modattu kitaristille sopivaksi. Bluesmasterin ”riisuttu” olemus myös tarkoittaa, että soittimesi soundi pysyy mallikkaasti ehjänä matkalla tulojakista kaiuttimeen.

Review: Bluetone Bluesmaster – Straightforward and to the point

No effect pedals were used on the guitar parts in this demo.
The original Fender Musicmaster Amp is a practice bass amp from the 70s and early 80s.

Fender’s original Musicmaster Bass amplifier was an odd concoction. The Musicmaster Amp was meant as a practice amplifier for beginning bassists – and sometimes even sold in a pack with the starter bass guitar of the same name – but it fell strangely flat of expectaions. The amp was underpowered and sounded flabby and uninspiring as a bass amp.

More recently, though, guitarists on the hunt for good bargains have come to realise that the Musicmaster Amp is a relatively inexpensive way to buy a genuine ”silverface” Fender. It’s a stripped-down valve amp for sure, but it still deliveres a lot of character, when used with an electric guitar. And because it isn’t a collectable Fender model, people feel free to modify the original for their own purposes.

This is where it starts to get interesting:

Finnish boutique amp maker Bluetone has released its own handcrafted and improved version of the Fender Musicmaster a few weeks ago, meant expressly for guitarists. This new guitar combo is called the Bluetone Bluesmaster, and it will set you back between 960 to 1,190 euros, depending on your chosen options and finish.

The signal path closely follows that of the original, but the Bluetone Bluesmaster adds such handy features as a Low Cut switch and the company’s own three-way rotary OPC-switch. The OPC-circuit (Output Power Control) enables you to drop the Bluesmaster’s output power from its full 10-12 watts down to something like 2 watts, virtually without any negative impact on the amplifier’s tone.

The original Musicmaster amp had been designed to reflect its low price tag. Fender’s engineers got rid of any components that weren’t strictly necessary to get the audio signal from the input to the speaker. Their most interesting – and quite unique, as it turns out – decision was to use an audio transformer for phase inverter-duties, instead of the much more common option of using a valve.

As you can see in the photo above, Bluetone has used the same basic design for the new Bluesmaster combo. Next to the three tubes – a single 12AX7 for the preamp, and a pair of 6V6GTs for the power amp – there are three (!) transformers. Two small ones for phase inversion and signal output, respectively, as well as a larger toroidal transformer for the combo’s power requirements.

The favourite modification on old Musicmasters is swapping the weedy-sounding original Fender for a beefier speaker.

The Bluetone Bluesmaster does this for you and comes workshop-equipped with a 10-inch Warehouse Guitar Speaker G10C/S. The G10C/S is part of WGS’s American Vintage range and is known for its clear, but round top end, as well as for its pedal-friendliness and smooth breakup. Other speakers are available as an option, too (see Bluetone’s website).

Apart from the power switch, the back panel offers a trio of speaker outputs.

Although the Bluetone Bluesmaster seems very straightforward and upfront at the beginning, there really is some sort of magic tone thing going on with this all-valve combo.

The sound may seem a bit dryish at first, but you will quickly notice a very enticing dose of juicy compression, even on very clean tones. This compression isn’t the ducking type, well known from many master volume amps and distortion pedals, which ducks the note attack and squashes the whole signal. Here we have a Country- and clean Blues-friendly type of compression that seems to lift the sustain phase of each ringing note.

Because this is a relatively low-powered tube combo without separate gain and master volume controls, it really makes sense to experiment with the Bluesmaster’s High- and Low-inputs and the combo’s volume control, to get the full picture of what sounds you can glean from which combination of guitar and settings.

The Bluetone Bluesmaster doesn’t offer tons of clean headroom, instead it has that magic clean-but-breaking-up tone zone down to a tee. The combo also works well with effect pedals.

There are also some chunky overdrive and distortion voicings available in the higher reaches of the Bluesmaster’s Volume-control. You should be aware, though, that, this being a non-master volume combo, running this amp at full tilt even at only 2 watts of output might get you into trouble with your neighbours in a block of flats.

All of the demo song’s guitar parts were played through the Bluetone Bluesmaster without any effect pedals. The guitar tracks were recorded with a Shure 545SD going into a Cranborne Audio Camden preamp.

• Rhythm guitars: Gibson Les Paul Junior (left), Fender Stratocaster (middle), Fender Telecaster (right)

• Lead guitar: Hamer USA Studio Custom

****

The Bluetone Bluesmaster does what it says on the proverbial tin. In my opinion, this is a very nice and straightforward silverface-inspired Blues amp for guitar. The excellent build quality and very sensible modifications and improvements result in a quality tube combo that will surely give you a lifetime of aural pleasure.
