Review: Vox VX15-GT

****

The new Vox VX15-GT (street price in Finland approx. 155 €) is an ultra-light, modelling practice amp with a 15-watt power amp.

The VX15-GT shares the control panel and signal-processing blocks with its larger brother, the VX50-GTV, but with one crucial difference. While the larger combo’s preamp section utilises Vox’ proprietary Nutube – a modern, low voltage tube – the VX15-GT uses Vox’ patented VET (Virtual Element Technology) digital modelling architecture.

The Vox VX15-GT’s astonishingly low weight (of just under four kilos) is achieved by using a special cabinet that is molded completely from ABS-plastic, as well as the use of a modern, lightweight power amplifier.

The single speaker is a 6.5-inch Vox unit.

The combo is powered by 12 volts DC from an external, laptop style AC adapter.

The internal preset memory holds 11 slots for factory presets (one per amp model) plus two storable user presets. By connecting an optional Vox VFS5 footswitch the number of user presets can be increased to eight.

****

The Vox VX15-GT’s top-facing control panel sports the typical control layout of most modelling practice amps:

Starting from the left we find an E-tuner above the guitar input. The tuner LEDs double as preset programme indicators – when all LEDS are off the combo is in manual mode, with all parameters corresponding to the current knob positions. The amp selector offers you ten different amplifier models – one Fender, two Dumbles, two Voxes, three Marshalls, one Soldano and one Mesa/Boogie. The Line setting disconnects the amp modelling section, so you can use the VX15-GT to amplify a line level signal, such as a synthesiser.

The four smaller knobs in the top row control the usual amplifier functions, namely gain, two-band EQ and programme volume.

The Modulation control lets you choose and adjust one of four different modulation effects – chorus, flanger, phaser (the abbreviation ”ORG” stands for the colour orange) and tremolo. The Modulation knob sweeps each effect’s speed from very slow to very fast. Here’s an audio clip running through the four modulation types, starting with the modulation section off:

The Delay/Reverb control lets you select one out of two delays or two reverbs. This control adjusts the chosen effect’s intensity (its volume in the mix), while the delay speed and the reverb length is set using the Tap Tempo button. For this clip I have set the delay time to almost full. I start off with a dry example and then play two examples of each effect, one with low and the other with high intensity:

As a demo song I recorded short cover version of the Weeknd’s song ”Blinding Lights”. All guitar tracks were played on a Gibson Melody Maker SG and recorded with a Shure SM57. I used only the Vox VX15-GT’s own effects:

Once I got over the unusual, all-plastic construction of the new Vox combo, I was really taken with the range of different sounds and the decent amounts of volume the VX15-GT has to offer.

This is a very inspiring and lightweight package, which, in my view, will work best as a practice (or teaching) guitar combo or in a small home studio setting.

One ”hidden”, but very nifty, feature that I haven’t mentioned is the very efficient, built-in noise suppressor. I was able to use single-coil pickups in the highest gain settings, without any 50-cycle hum!

You cannot compare the 15 watts of solid state power output to the full-on blast of an all-valve Vox AC15, but stick a decent microphone in front of it and you could even use the VX15-GT for the occasional pub gig.

Review: Roland Cube-10GX

****

cube-10gx_angle_black_gal

The new Roland Cube-10GX approaches the company’s popular Cube-concept from a slightly different angle.

****

cube-10gx_front_gal

The 10-watt Roland Cube-10GX (Finnish price approx. 125 €) slots into the model range right between the 3-watt Micro Cube GX and the 20-watt Cube-20GX combo.

Despite its very affordable price, the 10GX is built as sturdily as the larger Cube models, featuring chunky corner protectors, and the metal grille typical of this series.

An eight-inch speaker has been installed into the closed-back, front-ported cabinet.

cube-10gx_back_gal

The backpanel sports connections for DC In (the PSU comes included), Aux In, as well as a combined line level output/headphones jack.

cube-10gx_top_gal

The Cube-10GX combo’s architecture differs somewhat from the rest of the GX-models:

The 10GX doesn’t feature a built-in tuner or an i-Cube-Link, like the rest of the GX-models, but offers a much more open way of offering its COSM-generated amp models.

cube-kit-image_1800

The Cube-10GX lets you choose from a number of different amp models via the new Roland Cube Kit app (Android and iOS). At the moment of writing the app offers eight guitar amp models, plus one bass amp and one amp for acoustic guitar.

Despite the fact that the control panel reads ”Clean”, ”Crunch” and ”Lead”, you can load any of the COSM amp models on offer into any of the amp’s three channels. If you’re a Jazzer, for example, you might prefer to use only clean amps, like Acoustic, JC Clean and Black Panel.

****

cube-10gx_angle_gal

Let me deal with the ”bad news” first: Sadly, the Cube-10GX offers only a single effect section, in contrast to all the other Cube GX -combos. The 10GX gives you the choice between either a chorus or a delay or a hall reverb or a (very wet) spring reverb. And there are no effect combinations on offer.

The new combo’s main focus lies in the easy-to-swap amp models, and improvements in the sound of both the amp and the COSM-models. For a 10-watter the Cube-10GX is surprisingly loud. Thanks to its much larger speaker the new combo sounds much fuller and more grown up than the Micro Cube.

The updated COSM-models sound noticeably more transparent and fresher, without any additional background hiss or noise. The 10GX’ well-designed three-band EQ section lets you tailor the sound to your requirements.

Loading a new amp model into one of the Cube-10GX’ channels via the Cube Kit app is fast and easy, and doesn’t require any special cables. You only need a fitting mini-jack adapter to hook up the guitar lead to your smartphone (or tablet). All the necessary data is then transmitted from the Android- or iOS-device to the amp via the guitar cable. The whole process takes only a few taps and a couple of seconds.

The factory default has the Jazz Chorus amp model loaded into channel 1. I’m playing my Fender Telecaster with a little chorus added from the combo:

Here’s another Jazz Chorus clip, but this time seasoned with some Surf-type spring reverb:

The Classic Stack model is the factory setting for channel 2. It is Roland’s version of a Marshall-stack. I’ve added some delay for this clip:

I loaded the Brit Combo (AC30) model into channel 2, using the Cube Kit app. I’m playing my Telecaster with some reverb from the combo:

”Orng Stack” stands for Orange-stack. This is what it sounds like, played with my Gibson Melody Maker SG:

The factory default for channel 3 is the R-fier Stack model. First a clip using the Telecaster, and then an example Played with the Melody Maker SG:

The Cube Kit’s Acoustic model provides an easy solution for amplifying your acoustic guitar. I’ve used a Tanglewood dreadnought equipped with a magnetic soundhole pickup by Seymour Duncan:

The Cube-10GX even sounds surprisingly good as a tiny bass combo (all audio clips have been recorded with a Shure SM57):

****

Roland’s Cube-10GX (and the cool Cube Kit app) makes it possible to turn this little combo into the amp you really need. A Blues player will probably load his (or her) Cube-10GX with the Black Panel-, Brit Combo-, and Tweed-models, while a Metal guitarist will prefer the chunkier COSM-models on offer (like the Classic-, Metal- and R-fier-stacks).

The Cube-10GX sounds great and is a real little shouter. Despite offering fewer built-in effects than the rest of the GX-range, the Roland Cube-10GX still offers a lot of fun at a very competitive price.

Testipenkissä: Roland Cube-10GX

****

cube-10gx_angle_black_gal

Hiljattain ilmestynyt Roland Cube-10GX on Cube-perheen uusin jäsen, joka lähestyy firman suosittua Cube-reseptiä hieman toiselta kulmalta.

****

cube-10gx_front_gal

Kymmenwattinen Roland Cube-10GX (hintaluokka 125 €) asettuu vahvistinteholtaan kolmiwattisen Micro Cube GX:n ja 20-wattisen Cube-20GX-kombon väliin.

Kymppi-GX on edullisesta hinnastaan huolimatta samaa vankkaa tekoa kuin sen isot veljeksiä. Reilunkokoiset kulmasuojat ja Cube-sarjalle tyypillinen metalliritilä suojaavat kombon tehokkaasti monilta kolhuilta.

Koteloon on asennettu kahdeksantuumainen kaiutin.

cube-10gx_back_gal

Takapaneelista löytyy virtaliittimen (verkkolaite kuuluu hintaan) lisäksi aux-tulo, sekä yhdistetty kuuloke- ja linjalähtö.

cube-10gx_top_gal

Cube-10GX-kombon arkkitehtuuri poikkeaa toisista Cube-perheen GX-malleista:

Muiden GX-kombojen viritysmittarit ja i-Cube-Link-lähdöt puuttuvat tästä mallista, mutta niiden tilalle uudessa Cubessa tarjotaan huomattavasti avoimempi rakenne COSM-vahvistinosiossa.

cube-kit-image_1800

Cube-10GX tarjoaa nimittäin uuden Roland Cube Kit -appsin kautta (Android ja iOS) kitaristeille mahdollisuuden valita ja vaihtaa oman Cuben COSM-mallinnuksia oman maun ja käyttötarpeen mukaan. Tällä hetkellä Cube Kitistä löytyy kahdeksan sähkövahvistinmallia, yksi vahvistinmalli mikitetylle akustiselle kitaralle, sekä yksi bassovahvistin.

Vaikka kombon etupaneelissa lukee sen kolmen kanavapaikkojen kohdalla Clean, Crunch ja Lead, käyttäjä saa valita appsin kautta vapaasti kanaviin juuri niitä COSM-malleja, joita hän itse haluaa – vaikkapa vain puhtaita vaihtoehtoja, kuten Acoustic, JC Clean ja Black Panel.

****

cube-10gx_angle_gal

Kerron sen ”huonon uutisen” ensin: Olisin kernaasti nähnyt myös uudessa Cube-10GX-mallissa kaksi efektiosastoa, niin kuin esimerkiksi Micro Cube GX:ssä! Kymppi-GX-kombossa voi valita joko choruksen tai viiveen tai kaiun tai (reilusti annostetun) jousikaiun, eikä yhdistelmäefektejä ole tarjolla lainkaan.

Uutuuskombon painopiste on siis selvästi vahvistimen soundissa ja entistäkin parannetuissa COSM-mallinnuksissa. Cube-10GX on yllättävän äänekäs vahvistin 10-wattiselle kombolle, ja sen kahdeksantuumaisen kaiuttimen ansiosta tämän Rolandin yleissoundi on paljon syvempi ja aikuisempi kuin esimerkiksi Micro Cubessa.

Uudistetuissa COSM-malleissa on myös selvästi rapeampi, erottelevampi soundi, ilman lisättyä kohinaa. Kymppi-GX:n musikaalisesta kolmialueisesta EQ:sta on todella paljon apua soundien muokkaamisessa.

Soundien vaihtaminen Cube Kit -appsilla onnistuu erittäin helposti ja – mikä on parasta – täysin ilman erikoisjohtoja. Tarvitaan vain puhelimen (tai tabletin) ja kitarajohdon väliin sopiva kuulokeadapteri, jolla saadaan ohjelman dataa kulkemaan Android- tai iOS-laitteen kuulokelähdöstä kitarajohdon kautta Cube-10GX:een. Muutama täppäys vaan ja valitun kanavan COSM-malli on vaihdettu uuteen.

Tehdasasetuksena kombon ykköskanavassa on valittu Roland Jazz Chorus -kombon mallinnus. Tässä soitan Fender Telecasterilla ykköskanavan läpi ja chorus-efekti on päällä:

Myös tässä käytän Jazz Chorus -mallia, mutta tällä kertaa Surf-tyylisellä jousikaiku-efektillä:

Classic Stack on kakkoskanavan tehdasasetus. Se on Rolandin COSM-versio Marshall-stäkistä, jota kuullaan tässä delay-efektillä höystettynä:

Latasin Cube Kitillä kakkoskanavalle Brit Combo -mallin (AC30). Soitan Telecasterilla ja käytän kombon kaikua:

Orange-stäkkiä matkiva Orng Stack -malli kuulostaa tällaiselta Gibson Melody Maker SG:ltä soitettuna:

Tehtaalta on asennettu kolmoskanavaan R-fier Stack -malli – siis Rectifier-meininkiä (ensin Telecasterilla, sen jälkeen Melody Maker SG:llä soitettuna):

Cube Kitin Acoustic-malli tarjoaa nopean ja helppokäyttöisen ratkaisun akustisen kitaran vahvistamiseen (tässä Tanglewood teräskielinen magneettisella Seymour Duncan -mikrofonilla):

Cube-10GX kuulostaa yllättävän isolta myös bassovahvistimena (kaikki ääninäytteet äänitetty Shure SM57:lla):

****

Rolandin Cube-10GX tarjoaa firman oivan Cube Kit -appsin ansiosta jokaiselle kitaristille juuri sen vahvistimen, jonka hän tarvitsee ja haluaa. Bluesmies (tai -nainen) voisi esimerkiksi ladata kymppi-GX:n kolmelle kanavapaikalle Black Panel-, Brit Combo-, sekä Tweed-mallit, kun taas rankan musiikin ystävä voi tehdä pikkustyrkkarista metallimusiikkiin erikoistuneen koneen (esimerkiksi valitsemalla Classic-, Metal- ja R-fier-stäkit).

Cube-10GX:stä lähtee niin paljon – ja etenkin niin laadukasta – ääntä, että tämän kombon (muihin GX-malliin nähden) supistetulla efektivalikoimalla ei ole mielestäni oikeastaan niin paljon väliä. Roland Cube-10GX tarjoaa todella paljon vahvistinta edulliseen hintaan.
