Review: Bluetone Load Box

Finnish boutique amp company Bluetone has released a Swiss Army Knife-style lifesaver for valve amp users on stage and in the studio.

The Bluetone Load Box (370 €; incl. 1.5 metre speaker cable) is a professional quality dummy load (100 W/8 Ω) in a very compact format (only slightly larger than a big paperback) that doubles as a DI-box for guitar amps.

As any valve amp user should know, using an amplifier with a valve-driven power amp without a speaker (cabinet) connected – unless expressly allowed by the manufacturer – is a surefire path to disaster. The results of driving an amp without a speaker load can range from the output transformer catching fire to larger-scale component meltdown inside the amp, depending on the volume levels the amplifier is played at, and how quickly the fuses react.

This is where load boxes – also called dummy loads – come in. A load box allows you to run a valve amp safely without any speaker connected, while usually also offering signal attenuation and/or line level outputs. As a result, you are able to direct inject any amp into a PA system or recording equipment, as well as running the amp at full tilt without blasting everybody off the stage.

Doing away with the speaker (cabinet) isn’t as straightforward as you might think, because the impedance stated on a speaker is only nominal. The speaker, being an electromechanical transducer, behaves in a frequency- and signal level-dependent way, which results in dynamically shifting impedance values.

This means that a dummy load is a much more involved design than just a few resistors thrown together. Dummy coils, and a heap of capacitors and resistors are needed to simulate realistically the behaviour of a speaker, to attenuate the speaker signal (by dissipating part of it as heat), and to produce a quality DI-signal.


Bluetone’s Load Box has a very clear and logical layout:

The left side carries all speaker-related connectors, offering an input, as well as both an attenuated output (Speaker Out) and a straight speaker output (Speaker Through). Why would anyone need two speaker outputs? The answer is simple: If you want to run an isolated cabinet backstage at full speaker output for the FOH engineer, and an attenuated speaker signal for the backline to keep onstage volume levels manageable.

The right side sports two output jacks – one is carrying a headphone signal, while the other one is the balanced output for connection to a mixing console or a soundcard.

The controls and switches are self-explanatory:

Top left is a four-way rotary switch for speaker attenuation, with ”Off” muting the Speaker Out signal completely. I should also mention that you can use the Bluetone Load Box without any speakers connected, regardless of the selector setting.

The middle knob is the headphone level control. Because the Load Box is a completely passive design – meaning there’s no need for any sort of power supply – the output level of the headphone output is directly dependent on the signal level (and wattage) of the connected amplifier. On the early production model used for this review the headphone signal can be a tiny bit on the quiet side, when using a low-wattage amp and power hungry headphones. This is a known issue, and Bluetone will increase the signal level in future.

The line level output offers a healthy output levels. If you need an XLR connector for the Load Box’ balanced output, Bluetone offers a handy adapter for 20 €.

A three-way mini toggle gives you two different types of cabinet simulation – 1 x 12″ and 4 x 12″ – while its two-way counterpart makes it possible to bypass speaker simulation for the Line Out signal.

The Bluetone Load Box’ dummy load and attenuator work really well in dropping volume levels while keeping virtually all of your amp’s tone intact. Now you can run your non-master volume valve amp at pub-friendly levels, without sacrificing your sound.

Bluetone’s DI-output captures your amp’s tone without the need for a speaker cabinet and microphones, which is great news for home recordists and small project studios. The Load Box’ analogue speaker modelling offers a fine solution for capturing your sound with the least amount of fuss.

Here’s what my Fender Strat sounds like played through a Bluetone Shadows Jr. combo on clean settings, and recorded with a Shure SM57:

Here’s the same clean example direct recorded with the Load Box set to 1 x 12″:

Here’s a distorted clip with the sound of the Shadows Jr. recorded with the SM57:

And the same clip recorded through the Load Box:


In my opinion the Bluetone Load Box offers great value for money. Bluetone’s compact Load Box is a product every owner of a valve amp that doesn’t come with output attenuation built in should at least consider adding to his/her equipment.

The clever bit is how Bluetone has managed to fit the different functions into a lightweight, easy-to-carry, handcrafted piece of equipment. The Load Box is a sturdy device that will get the job done with the minimum amount of fuss, and it comes at a fair price.

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: Tokai TJM-140

We at Kitarablogi HQ received a very special instrument for review this time – the new Tokai TJM-140, which is based on Fender’s Jazzmaster.

When the original Jazzmaster was released in 1958 Fender aimed it squarely at Jazz and Lounge musicians, who had found the company’s earlier offerings much too bright and Country-sounding. The Jazzmaster also was Fender’s first model with a rosewood fingerboard, something their sales force had been requesting for years (for cosmetic reasons).

Sadly, the new model wasn’t received very enthusiastically. Most Jazz guitarists still felt that Fender guitars were nothing more than mere breadboards with strings, while others complained that the new control setup was too complicated. A shame, really…

Over the last years Jazzmaster-type offset guitars have definitely become en vogue again. Thanks to this trend Tokai, too, has decided to come up with its own version of this guitar classic.


The Tokai TJM-140 Silver Star (reviewed version: 1.495 €; basic model: 1.445 €) is a top-quality Japanese rendition of the Jazzmaster model, which stays faithful to the original classic in most respects, with a few modern improvements. The review sample has been customised further with a set of Seymour Duncan Antiquity pickups.

Tokai’s TJM-140 strongly channels an early-Sixties spirit – this guitar comes with the original, small Fender-style headstock, as well as an unbound rosewood fretboard with small dot markers.

Beneath its classy Olympic White finish the curvaceous body is crafted from alder, while the satin-finished neck is maple.

Putting the truss rod adjustment at the headstock end is one of the welcome improvements on the TJM-140.

The Tokai sports a set of fine Kluson copies made by Gotoh.

This model comes with 22 medium-sized frets. The fretwork is very clean.

Leo Fender had a thing for vibratos, which he called tremolos. For the Jazzmaster he came up with a special new system. The Jazzmaster-vibrato (which was later used on the Jaguar, too) comprises a front-installed vibrato/tailpiece-combination, paired with a separate bridge. The bridge stands on height-adjustable poles inside long ferrules, and it rocks slightly back and forth during vibrato use. The Tokai Silver Star uses a well-made Japanese copy of the original system.

You don’t need to be a guitar expert to see that Leo Fender was aiming for a Gibson P-90-vibe with his flat and wide Jazzmaster pickups. Both the P-90 and Jazzmaster pickup have similar coils, but their magnetic structure puts them apart. Gibson’s P-90 uses two long bar magnets placed underneath the coil, either side of a metal spacer, to magnetise its pickup. Fender, on the other hand, uses six slug magnets, which also serve as the pickup’s pole pieces.

The pickups in Seymour Duncan’s Antiquity-set are reverse wound/reverse polarity, resulting in a hum-cancelling middle position on the toggle switch.

The special feature of Jazzmasters is the so-called rhythm circuit. The slide switch above the neck pickup switches between the lead and rhythm circuits. In rhythm, only the neck pickup is selected, with a slight treble roll-off and its own set of volume and tone control wheels.

The solo circuit uses the regular set of controls – a three-position toggle, plus master volume and tone. Each circuit works independently of the other’s settings.


In my view, every guitarist should try a Jazzmaster- or Jaguar-style guitar once in his/her life, just to experience that comfortable offset body. Some players feel that the offset waist of a Jazzmaster is even more ergonomic that a Strat.

The Tokai TJM-140 is a fine example of a Jazzmaster-style guitar. Our test sample is light in weight, the neck’s oval C-profile feels great in your hand, and the guitar arrived with an expert setup.

Still, the Jazzmaster-vibrato will continue to divide opinions for the foreseeable future. The push-fit vibrato arm isn’t as foolproof as the screw-in Stratocaster arm, and it tends to swing rather loosely, when not in use. With a contemporary string set of 009- or 010-gauge you will probably run into some problems sooner or later, due to the shallow string angle over the bridge. Forceful strumming and/or large bends tend to cause light string gauges to jump out of the bridge saddles’ grooves, spoiling your setup and tuning in the process.

You cannot blame the Tokai TJM-140 Silver Star for using a faithful copy of the original vibrato, because this guitar is meant to be a vintage-inspired instrument. Nevertheless, it’s important to know about any possible pitfalls and solutions.

The easiest way to get a Jazzmaster-vibrato to play nicely is to use the correct string gauges of the late 1950s – read: flatwound 011s or 012s with a wound g-string. If this seems unbearable there’s always the screw-on Whizzo Buzz Stop, a Bigsby-style roller that adds much-needed downward pressure at the tailpiece. Others like to take the far more drastic step of replacing the whole Jazzmaster-system with a Mastery-vibrato, a replacement made specifically for use with modern strings.

Tokai’s TJM-140 Silver Star nails the Jazzmaster tone like a champion. The Antiquity pickups give you lots of chime and sparkle, but the top end is much warmer than on a Strat, and there’s a nice dose of mid-range chunk. The rhythm circuit rolls off a little bit of the neck pickup’s treble, but still keeps things from going all dark and muddy.

Here are a few clips of the Tokai TJM-140, recorded with a Bluetone Shadows Jr. combo, a Boss SD-1 overdrive and a Shure SM57:


Tokai’s TJM-140 is a pro quality Japanese version of the Fender Jazzmaster. The Tokai plays and feels great, and its sound really leaves nothing to be desired. The original Jazzmaster-/Jaguar-vibrato might become a deal-breaker for some, but I feel the original system adds a lot to this guitar’s sound and mystique. Tokai uses a high-quality copy of the original vibrato, which works as smoothly as it should. Taking this instrument for a spin is highly recommended!
