Press Release: The Ruokangas Valvebucker pickup

Ruokangas unveils the Valvebucker® – the first and only tube driven electric guitar pickup in the world


The Valvebucker® is “just one pickup” – and yet, it offers a whole array of different sounds. The Valvebucker® functions in a different way than other pickups, and thus a guitar equipped with a Valvebucker® doesn’t quite fit any old school genre of guitars – its wide tonal spectrum and organic dynamics are simply different from other guitars.

The design architecture of the Valvebucker® circuit is noteworthy, making use of sweet spots found from outside the typical operational points of vacuum tubes, by using relatively low voltages. The power consumption of the Valvebucker® remains within the given values also during startup – an important feature when using commercially available pedal power units. Every Valvebucker® unit is handmade and finetuned individually in Finland. The Valvebucker® design team is: Lassi Ukkonen (the designer of Simble Overdrive, etc), Jorma Kostamo, Jyrki Kostamo and Juha Ruokangas.

The Valvebucker® will be introduced at The NAMM Show 2019. The Valvebucker® is available as a custom option for Ruokangas guitars from January 2019 on, adding EUR 1200 to the cost of an ordered instrument.

The Valvebucker® features include:
Tube amplified active preamp circuit
Military grade triode and pentode NOS tubes with lifetime warranty
Volume and Tone controls
3-way switch for a variety of sounds
2-way boost switch
A floor unit included, to connect the Valvebucker® -equipped guitar with the rest of your signal chain
A 12VAC power supply included
A 10-foot XLR cable included

This is how the Valvebucker® works

Your Valvebucker -equipped guitar comes with a floor unit in the size of a standard guitar FX pedal. You connect the Valvebucker guitar to the floor unit with a standard XLR microphone cable.

The Valvebucker is powered through the floor unit, that connects to a 12VAC power source. Use either your regular pedal power (12VAC, min. 250mA) or the power supply provided with the guitar.

The floor unit has two inputs and a true bypass A/B switch to easily alternate between the Valvebucker -equipped guitar and the rest of your guitars. The signal chain continues through the floor unit normally to your pedalboard and/or amplifier.

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.
