Bluetone introduces the Load Box

Bluetone’s brand-new Load Box is a 8 ohm/100 watts multi-purpose reactive and passive attenuator for live use and recording.

It comes with the following features:

  • Scalable 100 W dummy load with -12 dB, -15 dB and -20 dB and Off  steps for output level attenuation, even up to total silence.
  • Speaker Through jack, which is parallel with the Speaker In jack. This also works with a 4 ohm speaker output from the amplifier.
  • Speaker Out jack carrying the attenuated guitar signal.
  • Analogue cabinet simulator with 1×12″, 4×12″, and off (bypass) settings.
  • Balanced adjustable Line Out with a jack connector.
  • Dry–PA/Rec switch for the line level signal.
  • Adjustable Headphones Out for use with headphones.

The Load Box is completely passive, which means it doesn’t require a power supply to function.

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.
