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.

****

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.

****

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.

Buying an electric guitar, part 4 – What accessories do I need?

In this last part of our series we take a look at what a beginner needs to make the most of his/her new guitar.

• Amplification

An electric guitar needs some type of amplification. Yes, it’s true that you can play an electric guitar unplugged, too, but to develop a good technique you should use an amplifier regularly. Especially with solid body guitars there’s always the temptation to play them too hard, when playing unplugged.

You can either go for a headphone amp…

…or a practice amp, meaning a small, low-powered combo.

• A cable (aka a lead)

You will need an instrument cable to connect your guitar to your amp. Most leads that come with less expensive guitars (sub 1,000 €) are very cheap and nasty – don’t use them.

A quality guitar cable is made from sturdy cable material, which is well-shielded from electromagnetic interference, and it sports two quality plugs.

If you use a Gibson SG-type guitar or any semiacoustic with an output jack mounted to its top, you should get a guitar lead that has an angled plug to use with the guitar. The angled plug will put less mechanical stress on the crucial area around the jack.

****

• A bag or a case

The safest place for your instrument, when it’s not played, is a well-made gig bag or a hard case.

A well-padded gig bag is lightweight and easy to transport, especially if you travel by public transport or by bike.

More expensive guitars – especially those with set necks – should really be stored in a case. You should also opt for a case if you plan on transporting your instrument in the back of a van or in a trailer, as a case is much sturdier than a gig bag.

****

• A stand

On stage – or during practice session breaks – you should put your guitar in a guitar stand, when you’re not playing it. Leaning it against the amp or leaving it lying on the floor will result in accidents sooner rather than later.

If your guitar is finished in nitrocellulose lacquer (which means all Gibsons, some upper range Fenders, many luthier-made instruments), you have to make sure to buy a stand that won’t react chemically with your guitar’s finish. Some stands have padding that can leave marks on your guitar, or even cause the finish to blister. Some guitarists even line the contact areas of their stands with linen or cotton cloth to protect their nitro-finished instrument.

****

 • A tuner

A digital tuner will help you play in tune with the rest of the band. It is also an indispensable tool for setting your guitar’s intonation.

Tuners are available as clip-on units…

…table top tuners…

…or as floor ”effects”.

****

• Strings

It’s a very good idea to have one or two sets of strings in your gig bag or case, in case you break a string.

If you’re unsure about the correct gauge, ask the shop assistant (or the seller) to tell you what gauge the current string set on the guitar is. You can find more information about string changes HERE.

****

•  Plectrums

Most guitarists use a plectrum (aka a pick) to strum their electric guitar.

Picks are available in a plethora of different materials, thicknesses, colours and sizes. Luckily, plectrums are also quite inexpensive, so I’d suggest you try a few different picks, before deciding on your personal preference.

The Making of a Bluetone Amp – Part 4

Bluetone part 4 – 2

So here’s the finished guitar amplifier:

The new Bluetone Crossroad 2+2 amp head is fitted inside its cabinet, and Bluetone’s game-changing wifi-software is up and running smoothly.

Bluetone part 4 – 3

Bluetone’s wifi-protocol makes it easy to check and readjust the tube bias on your amplifier’s power tubes. No engineering degree or special tools needed – you only have to have a mobile device or computer to hand.

Bluetone part 4 – 4

The amp head is accessed as a web-address. The correct bias values for the power amp valves fitting your amp are listed in the owner’s manual. All you have to do is to type the new bias values into the correct fields, and save them by pressing the ”Change Bias” buttons.

Bluetone part 4 – 1

This is what the finished half-stack looks like. It has already been taken home by its lucky owner.

The Making of a Bluetone Amp – Part 3

Bluetone Pt3 – 1

The time-consuming process of hand-wiring, assembling and soldering the innards of the new Bluetone Crossroad amp head was practically finished by the start of last week. The only thing still missing was the software to run the wifi power valve biasing (the traditional, hardwired bias adjustment already worked, of course).

Bluetone Pt3 – 2

Bluetone Pt3 – 3

Bluetone Pt3 – 4

This is the way a custom-made guitar amplifier should look on the inside – exemplary workmanship and top grade components.

Bluetone Pt3 – 5

Bluetone Pt3 – 6

Bluetone Pt3 – 7

There was still a tiny bit of adjustment work to be done on the metal chassis to make it fit properly into its cabinet.

Bluetone Pt3 –8

When all is finished the control panel should be flush with the cloth grille.

From a tonal perspective the Crossroad-head was all dialled-in, thoroughly checked and rearing to go. Matti and Harry gave me a run-through of the sounds offered by this amp’s three channels, and I must say it sounded fantastic!

Only a few hours after my visit to Bluetone’s HQ, I got a message from Harry that the wifi-application had arrived for inclusion in the head.

Näin syntyy Bluetone-vahvistin – osa 4
