Here’s a short Blues demo of the Tech 21 SansAmp Character Plus Screaming Blonde. The Screaming Blonde offers two channels of Fender-type amp simulation and a switchable Tube Screamer-style overdrive.

If you’ve always lusted for a hand-soldered guitar amp you were left with two options until quite recently:
You could either buy an expensive boutique/custom shop amplifier, or – if you’re handy with a soldering iron – opt for a DIY amp kit.
Now there’s a third choice for those of us neither well-heeled nor technically savvy:
British company Juketone offers a range of tasty Fender tweed inspired, hand-wired guitar amplifiers at very moderate prices, thanks to Chinese production and selling direct via the Internet.
****
The Juketone True Blood (250 £; introductory offer for a limited time only) is the company’s smallest combo.
The True Blood is based on Fender’s legendary 1950s Tweed Champ (specifically the 5F1 version), with a few small tweaks.
Tweed Champs have been built with several differently shaped cabinets over the Fifties, depending on their exact vintage. The True Blood comes in the all-straight cabinet seen on most mid-Fifties originals, while Fender’s current Custom Shop version features the later angled front.
The tweed covering on our review sample was very neat and crisp.
The combo’s cabinet is made of plywood, except for the back covers, which looked (and felt) like MDF-board.
The two most important differences between a vintage Champ and Juketone’s True Blood combo lie in the speaker-type and rectifier valve choices.
In addition to the two audio signal valves – a Ruby Tubes 12AX7 and a 6V6GT – Juketone has chosen a slightly less-known 6Z4 rectifier tube. The 6Z4 used in Juketone amps is a Chinese version (aka the Sino 6Z4) that is not compatible with the American rectifier valve of the same name.
Jensen has traditionally been the speaker brand of choice for vintage tweed amps, but their bass response very often sounds a bit flabby by modern standards. In my opinion, Juketone has made a very good decision in choosing a more British-voiced speaker for their True Blood combo. The eight-inch Celestion Super 8 could be described as an alnico-driven version of their popular Eight 15.
Inside the metal amp chassis you will be greeted by high quality components and clean workmanship. This is genuine hand-soldering using soldering lugs riveted to a fibreglass board.
You’d be foolish to expect the wiring to be on the same, insanely high level – in terms of its neatness – as generally seen on boutique-grade amps, but the True Blood is definitely in line with Juketone’s ”affordable boutique” ethos.

Maybe the most important part in the charm of a 5F1-type Champ (or Champ clone) is the directness of this small combo’s approach to tonal nirvana. There’s no master volume, no tone control, no effects – just a single volume control, and the straightest signal path from input jack to speaker known to mankind.
To some, this type of diminutive Fifties practice amp looks like it’s hopelessly ancient, but the Tweed Champ still has a lot of fans.
The Juketone True Blood’s secret to success lies in the combo’s interactive behaviour. The most traditional way to use the True Blood would be to dial in the maximum amount of volume (and distortion) needed, and then control the amp using the guitar’s own volume and tone controls. Thanks to the naturally rich compression this combo produces when pushed, turning down the guitar volume for cleaner sounds will result in less of a volume drop than expected. Here’s a short clip using a double humbucker guitar (Hamer USA Studio Custom):
If you need more clean headroom from your True Blood (Blues harpists, listen up) than what the factory 12AX7 has to offer, you could easily drop in one of a number of ”cooler” 12A_7-family replacements, such as a 12AU7 or a 12AT7.
Here are three clips of a Fender Telecaster, a Gibson Les Paul Junior and a Hamer Studio Custom, respectively, with their bridge pickups selected. Each clip has been recorded with the combo’s volume control set to ”6”, ”8”, ”10” and ”12”, using a Shure SM57:
The Juketone True Blood’s low volume and tasty compression make this combo an excellent choice for use in the (home-) studio. Just add a little EQ and compression, and season the result with a bit of reverb and/or delay during mixdown, and you’ll be surprised at how big this little chap really sounds:
****
I can only recommend Juketone’s True Blood warmly for use as a living room and recording amp.
Laying your hands on a hand-wired tweed-style combo has never been so easy or affordable. The warm, big bass response of the Celestion speaker is a definite improvement, at least in my book!
This Juketone combo is a serious alternative to your run-of-the-mill mass-produced practice. It sounds pure and sweet. A hand-soldered combo, such as this, is also far easier to repair (or modify) than a PCB-based design.
Jos on halunnut itselleen uuden, käsinjuotetun putkivahvistimen, vaihtoehtoja on tähän mennessä ollut käytännössä kaksi – joko ostaa kallis boutique- tai custom shop –vahvistin, tai kasata vahvistin rakennussarjan pohjalta.
Brittiläinen Juketone tarjoaa kuitenkin kolmannenkin vaihtoehdon tweed-faneille – edullisia, Fender-henkisiä putkivahvistimia, jotka suunnitellaan Englannissa ja valmistetaan Kiinassa.
True Blood perustuu suurilta osin legendaariseen 1950-luvun Fender Champ -komboon (5F1-versio), johon Juketone on tehnyt pieniä muutoksia.
Tweed-Champeja on rakennettu 1950-luvun eri vaiheissa kolmella eri kaiutinkotelolla. True Bloodin kaiutinkotelo on kokonaan suorakaiteinen (niin kuin 1955/56-malleissa), kun taas Fenderin Custom Shop -versiossa pohja on syvempi kuin kansi (50-luvun lopun versio).
Tweed-kankaalla päällystetty kotelo on valmistettu lähes täysin vanerista, lukuun ottamatta takalevyjä, jotka ovat kuitulevyä.
Tärkeimmät erot vanhan Champin ja Juketonen True Bloodin välillä löytyvät tasasuuntaajaputkesta ja kaiuttimesta.
Audio-osaston Ruby Tubes 12AX7- ja 6V6GT -putkien lisäksi vahvistimesta löytyy hieman harvinaisempi kiinalainen 6Z4-tasasuuntaaja, joka ei ole yhteensopiva samannimisen amerikkalaisen putkityypin kanssa.
Vanhoissa tweed-Champeissa on yleensä Jensen-kaiutin, mutta Juketone on valinnut komboonsa selvästi brittiläisemman, kahdeksantuumaisen Celestion Super 8 -mallin, joka on alnico-versio saman valmistajan suositusta Eight 15 -kaiuttimesta.
Metallisen vahvistinkotelon sisältä löytyy kauttaaltaan laadukkaita komponentteja, jotka on juotettu siististi lasikuitulevyn juotoskorviin.
Työnjälki ei kuitenkaan (luonnollisesti) ole aivan samalla viivalla verrattuna esimerikiksi Bluetonen valmistamiin boutique -vahvistimiin, joissa styrkkarin sisälmykset näyttävät suorastaan taideteokselta. Juketone True Blood tarjoaa kuitenkin hämmästyttävän laadukkaan putkivahvistinelämyksen todella edullisesti.
****
Tärkeä osa 5F1-tyypisten Champien (ja Champ-kloonien) viehätystä on se, että ne tarjoavat soundille suorimman mahdollisen tien kitarasta kaiuttimelle. Ei masteria, ei taajuuskorjaimia, ei efektejä – yksi kanava, kaksi tuloa ja pelkkä volume-säädin, siinä kaikki!
Vaikka tämä 1950-luvun harjoituskombo vaikuttaakin monien silmistä muinaisesineeltä, on Tweed Champillä silti yhä monta ystävää.
Juketone True Blood -kombon salaisuus piilee vahvistimen interaktiivisuudessa. Luontevin tapa käyttää tällaista pikkukomboa on asettaa sen volume-säädin täysille (tai lähes täysille), ja hallita soundia soittimen omilla volume- ja tone-säätimillä. Vahvistimen tuottaman luontaisen kompression ansiosta saadaan eloisia ja täyteläisiä puhtaita soundeja myös pienelle säädetyillä humbuckerilla.
Jos kaipaa True Bloodilta hieman enemmän puhdasta headroomia (esim. huuliharppua vahvistettaessa), kannattaa etuasteessa kokeilla 12AX7-putken sijaan 12A_7-perheen hieman ”heikompia” malleja, kuten esimerkiksi 12AU7 tai 12AT7.
Tällä tavoin soivat Telecasterin, LP Juniorin ja Hamer Studio Customin tallamikrofonit True Blood -kombon kautta. Jokaisessa klipissä kombon Volume-säätimen asennot ovat ”6”, ”8”, ”10” ja ”12”. Taltiointiin on käytetty Shure SM57-mikrofonia:
Juketone True Bloodin pieni teho ja muhkea kompressio tekee kombosta myös oivan työkalun (koti-) studiossa. Hieman kaikua ja kompressiota, sekä pieni ripaus EQ:ta lisämausteiksi miksausvaiheessa, ja lopputulos kuulostaa paljon isommalta ja mehevämmältä kuin uskoisi:
****
Juketone True Blood on mielestäni oiva valinta suoraviivaista putkikomboa olohuoneeseen tai kotistudioon etsittäessä.
Se on helppo ja edullinen tapa saada itselleen aitoa tweed-tyylistä soundia. Celestion-kaiuttimen tuoma jäntevä keskialue ja muhkea basso ovat minun mielestäni ainoastaan plussaa!
Juketone-kombo on varteenotettava vaihtoehto tavallisille, massatuotetuille pikkukomboille – eikä vain hyvän soundinsa ansiosta. Käsinjuotetun elektroniikan etuja ovat myös helpompi huolto ja modifiointi.
In a way Blackstar Amplification’s new Artist Series breaks new ground for the British amp maker.
Until now most of Blackstar’s designs were based on the typically British tones of EL34 and EL84 power tubes, often associated with Marshall designs.
The new Artist combos feature power amps built around 6L6 valves, as used in many of Fender’s classic designs. According to Blackstar the new Artist amps are designed to combine the best bits of the typically British Class A tone (with two ECC83s in the preamp section) with the dynamic range and chiming top end of a 6L6 power section.
Kitarablogi.com was given the opportunity to take the smaller Artist model – the Blackstar Artist 15 (current price in Finland:799 €) for a spin.
****
The Blackstar Artist 15 looks like a typical Blackstar combo – black vinyl covering and a dark grey grille cloth.
For a combo that comes equipped with a single 12-inch speaker the amp’s cabinet is rather large. The reason for the cabinet’s size becomes clear when you look at the Artist 15 from behind.
The combo’s Celestion V-Type G12-speaker has been placed deliberately to one side of the combo. Blackstar doesn’t tell us exactly why this configuration has been chosen, but I’d wager that the idea behind this is to harness the benefits of a large, stiff front baffle and a larger cabinet – namely: a crisp attack, and a warm, full bottom end.
Celestion’s V-Type comes loaded with a ceramic magnet. According to Celestion this speaker combines a classic tonality with a modern power rating.
The Blackstar’s back panel sports a whole array of connectors for things such as external speaker cabinets, a speaker-emulated line out, an effects loop, as well as the channel footswitch that comes with the amp.

Blackstar’s Artist 15 is rated at 15 watts of output and features two preamp channels:
Channel 1 is the so-called boutique channel, designed to put the least possible amount of components between your guitar and the speaker. This channel sports only two controls – Volume and Tone – before the signal is sent on to the master section.
Channel 2 gives you the full Blackstar-experience – you’ll find separate Gain and Volume knobs, a three-band EQ section, as well as Blackstar’s proprietary ISF-control. Setting the ISF knob to zero will result in bright and sinewy Fender Blackface-style sounds, while ISF at full on will give you muscular, Marshall-type tones from this channel.
In addition to the Master Volume control, the Artist 15’s master section also includes the level control for the combo’s very nice digital reverb.
Channel 1 clearly has a much rounder and warmer basic tonality than the (more versatile) second channel. With clean settings Channel 1 will give you a fuller mid-range compared to the more Fender-like, chimey Channel 2.
Here’s what Channel 1 sounds like played clean with an Epiphone Casino (first clip) and a Gibson Melody Maker SG (second clip):
…and here’s Channel 2 played with the same guitars:
The Artist 15’s channels also differ in the amount of gain they offer:
Channel 1 will take you from clean all the way to Rockbilly-style breakup and traditional Blues overdrive, while Channel 2 offers more than enough dirt for chunky Rock tones.
Here’s Channel 1 at full gain (Casino and Melody Maker SG):
…and here are two clips of Channel 2 with Gain full up:
The rhythm guitar tracks on the demo song have been recorded with a 1970s Japanese ES-335 copy (made by Kasuga; left channel) and a maple-necked Fender Stratocaster (right channel). The lead is played on the Kasuga:
****
The new Blackstar Artist 15 isn’t your typical two-channel combo, which offers you a clean channel and a dirty channel. This is a valve amp that’s all about choices and flexibility.
Blackstar have noticed that pedalboards are becoming en vogue again, which is why their new Artist combos offer enough headroom for clean tones in both of their two channels.
For pedal users the big advantage of the Artist 15’s architecture lies in the fact that the combo offers two high-quality clean variants in the same amp. Channel 1 is a back-to-basics boutique-/AC30-style channel, while Channel 2 offers a much broader range of clean tones, all the way from Fender to modern Marshall.
Of course, you’re free to use the Blackstar Artist 15 in the traditional channel-switching fashion, too, which will give you a top-notch clean sound from Channel 1, and a very versatile array of quality overdriven and distorted tones from Channel 2.
Either way – the Blackstar Artist 15 hits bull’s-eye, in my opinion, and I can only recommend checking one out for yourselves.
