Hughes & Kettner amps might look like science fiction, but the German firm knows a think or two about classic tone and valves.
This is nicely showcased by the very special Alex Lifeson Signature Edition of the company's flagship TriAmp head.
H&K decided to issue this special amplifier to celebrate 30 years of collaboration between the company and the Rush guitarist – who's their highest-profile endorsee.
The amp is exceptionally well built and finished to a very high standard. It's electronically complex beast and, from necessity, the internals are all PCB-mounted.
The plywood sleeve is covered in thick vinyl with a unique love-it-or-hate-it imitation crocodile pattern.
It's a stunning effect especially as the LEDs are purple for the 'Alex' rather than the standard blue.
It's also very practical, making all the controls easy to see and adjust under any lighting conditions.
The amp has been carefully tweaked to Alex's exact requirements and Rush devotees love that the first 500 have individually numbered front panels and also include a special Rush CD, an R30 tour booklet and a certificate signed by Alex himself.
On the controls front, the 'Alex' is no different from a regular MkII TriAmp, which is to say that it's an incredible piece of work.
The TriAmp has three basic channels, but there's an awful lot more going on inside it, as you might guess from the whopping valve count of 13.
Each channel is designed as a completely different amplifier – having its own preamp circuit, master volume, three-band EQ and dual switchable gain controls for rhythm and lead use.
This gives you three distinctly different voicings and six footswitchable sounds in total.
Add in global master volume and presence and you can count 20 front panel rotary controls. Yet, despite this, the TriAmp is actually very easy to dial in and use.
Around the back you'll find more pro features, including a locking nine-pin 'D' connector for the TriAmp's stageboard, with half-power switching and insert points for the preamp and power amp in addition to the TriAmp's effects loop.
This can be switched in or out of circuit from the front panel or footswitch and has level switching, serial/parallel modes and a mix level control.
There's also a built-in Red Box speaker emulation circuit with a balanced XLR output for connecting the 'Alex' directly to a mixing desk without the need for microphones, either for recording or live PA use.
While the TriAmp doesn't come with it built in, MIDI can be enabled by purchasing a separate plug-in module, thus boosting this amp's versatility even further for those players who want it.
As mentioned, we're effectively dealing with three amps in one box, each with two footswitchable sounds.
Amp number one is primarily for clean stuff and delivers a whole gamut of classic 'Blackface' and 'Tweed'-influenced tone.
This channel incorporates a useful switch called 'tight', which reduces bass emphasis for a much snappier feel.
If you're using a 4 x 12 cabinet, bass frequencies can often end up sounding a little too flabby for decent clean sounds; the tight switch changes this to give a response more like that of an open-backed 2 x 12.
Amp number two is where you go for your favourite British tones; from classic 80s rock to thrash, it's all here, complete with a sweet, polished edge.
Amp number three puts some terrific lead sounds under your command, which are tightly defined and have a lot of character.
Compared to the regular MkII TriAmp, this signature amp's lead tones are subtly different, maybe a little sweeter and with a touch more clarity at higher volume.
There's massive distortion available here, but the most rewarding effects come from backing off the gain control to let the guitar's natural tone come through.
The sustain and definition that you'd expect for a great lead sound is still there at lower gain levels and, with the masters pushed up a little more, the 'Alex' really starts to sing.
In the super-amp league, the Alex Lifeson Signature Edition TriAmp MkII is easily capable of blowing most of the competition away.
Even at this lofty price, we reckon it's one of the top 10 amps in the world at the moment.
We'd urge players who want the best and can afford it to think 'outside the box' and put it on their audition list without hesitation.
