Randall RT503
Thursday, September 2nd, 2010
Many people associate Randall with its artists. Dimebag was a long-time user of the company’s solid-state amps and co-designed the Warhead. Likewise, Kurt Cobain used a solid-state Commander to record Nirvana’s debut, Bleach.
But Randall knows a thing or two about valves, too (take Kirk Hammet’s use of his RM120KH to inflict crippling high-gain tone), and is now offering its pure valve designs at a more affordable price with the RT Series, a family of traditional valve amps aimed at valve first-timers.
There are four amps in the range: a 50-watt, two-channel head and combo, and a pair of three-channel heads available in a 100 or 50-watt format. The latter RT503, our review model, gives you the full three-channel design (clean, OD1 and OD2) with separate EQs per channel for a more manageable output level.
It comes fitted with a pair of US staple 6L6 output valves, but these can be swapped for EL34s if you’re after a more British flavour. Biasing valve amps is usually best left to the experts, but the Bias control on the back of the amp lets you replace, swap and bias the valves yourself.
Randall’s clean sound has been divisive, but the RT’s dedicated clean channel goes some way towards remedying this. Boosting the preamp all the way for pushed sounds can get fizzy; it’s better to let the 6L6s do the work by keeping the preamp gain below three-quarters and pushing the power section. The reward ranges from spiky funk with our Strat’s singlecoils, up to a slightly driven jangle with humbuckers.
The clean channel’s bright switch is subtle, but once you’ve cranked the output you’ll notice the extra bite. Tipping OD1′s gain control just above zero results in a solid ‘in between clean and dirty’ tone. Above this things get progressively heavier with almost enough gain for metal at the top.
Select OD2 and you might as well don a poodle wig, bust out the pentatonics and write an album that becomes known by its sleeve colour. This is ‘Tallica territory. Where OD1 is fairly wide and open sounding, OD2 is tighter, meatier and, to our ears, more scooped.
The sub £1,000 price bracket has become a regular stomping ground for amp builders. While this amp does an admirable job of providing a range of sounds for different genres, Randall’s heritage rightly implies a penchant for the heavier end of the spectrum, and the RT503 seems happiest when you really allow it to wail.

Crafter GLXE-6000/RSB
Tuesday, August 10th, 2010
Crafter was once a predominately budget acoustic name and there are still models, such as the Lite and Silver Series, that occupy these lower price points.
Inexorably, however, the brand has been moving upmarket, exemplified not least in recent years by the all-solid-wood TV Series and the thin-line Slim Arch hybrid electros.
The most significant jump towards the pro sector came in 2007 with the launch of the GLXE cutaway grand auditorium electros, where high-grade all-solid timbers and specs were the order of the day, and whose ongoing 3000 and 4000 models nowadays retail over £1,000.
Upward evolution continues with the flagship GLXE-6000/ RSB, carrying a price tag just shy of £1,499. An appreciable sum of money, then, but the presentation is appropriately in the luxury mould, strikingly conveyed by the guitar’s back and sides.
Rather than simply the rosewood of its cheaper stable-mates, the 6000 adds a centre portion of lighter-hued bubinga to the back and across the end-block, the two timbers separated by coach-lined fillets of maple: very tasty, as is the quality of the body’s gloss livery and the instrument’s overall standard of build and detailing.
Decoration on our sample’s super-clean, reassuringly cross-silked German spruce top includes rosewood-bound abalone purfling, a sound-hole rosette of similar shell surrounding a central ring of back-matching bubinga, and a wing-style ebony bridge carrying a small bird-in-flight inlay at either end.
This theme is continued for the position markers along the ebony fingerboard, which is smartly edged in two-ply black/white binding. Up on the ebony overlaid headstock sit a set of gold Gotoh 510 deluxe tuners.
Gearing is 18:1, which provides very smooth adjustment; although some players may feel they’re a little low-geared. They do look the part, though.
Quite a few Crafters come with semi-wide finger-style necks, and this is what we find on the 6000. Kicking off at 44.5mm across the nut, the satin-finish one-piece mahogany affair broadens a fair bit further up, but thanks to a reasonably moderate-depth ‘C’ profile and a gentle fretboard camber, it’s a comfortable, fast playing handful, fulfilling the requirements for both accessible strummage and spacious, well-defined picking.
There are, however, a couple of aspects on our sample that merit a bit more attention: the fret ends feel a tad sharp, even if the fretting is otherwise nicely fitted and dressed; similarly, the front corners of the bone nut need rounding off to eliminate slightly painful contact against the side of your hand when moving back to open-position playing.
Arguably, and despite a speedy, lowish overall action, the nut slots would benefit from being cut lower to reduce the risk of finger-pressure intonation wobbles, which occur occasionally at low positions on the A and bottom E strings. These, though, are all things that can be easily sorted as part of a final pre-buy set-up.
Crafter has developed various preamp systems over the years, and the GLXE-6000′s is the new LR-T DX paired with an LR Baggs Element under-saddle pickup. Like the company’s Stage Pro Tuner system the DX offers four-band EQ and phase, but goes on to add a notch filter (0-300Hz) and a more sophisticated tuner that can be switched between auto-chromatic and preset string modes.
Underneath an LED arrows-cum-dot arrangement to indicate pitch status, the LCD depicts a virtual needle and the display’s backlight changes from amber to green as additional confirmation that a string has hit pitch. It’s fast, accurate, bright and very easy to read. The tuner also usefully mutes the system when activated while powered up (something the Stage Pro doesn’t do). It can also be used acoustically.
Another upgrade – which allows simultaneous running to backline and PA – is the provision of jack and XLR outputs on a panel adjacent to the endpin. The panel also houses the quick-release battery holder, where previous systems have had theirs incorporated in the preamp.
This GLXE is a physically quite heavy instrument (tipping the scales at 5.5lb), which in theory could militate against resonance. In reality, although there’s a faint element of compression to the dynamics, the acoustic delivery is good, combining decent clarity, note definition and sustain with a tonal blend of warmish lows and bright-ish highs.
Powered performance is something of a mixed bag, though it should be stressed that our guitar is a very early production sample (that also did duty at the Frankfurt MusikMesse for the model’s European launch), which might explain why the preamp doesn’t seem to be fully fettled.
In what way? Well, the bass EQ is decidedly odd. When notching is off, the band actually seems to work in reverse, producing subtly greater low-end at full cut than full boost! This sorts itself when notching is brought into play, but low-frequency tonal variation remains very, very modest – hugely less than the quoted +/-12dB range ought to achieve.
Our sample also isn’t helped by slightly dominant top and bottom E outputs, but that’s presumably down to the under-saddle set-up.
Fortunately the system performs well in all other respects. There’s a decent amount of gain; the tonal scope of treble and presence is sensibly considered, with the anticipated interactivity depending on the bands’ relative settings; phase and notch filter are effective in their own right, and the midrange EQ is very sympathetically judged. It duly scoops when cut, and when boosted introduces a pleasant, creamy jazzy timbre, not the honky stridency that’s sadly often the case with mid boosts.
It’s a shame that an aspect of the preamp’s behaviour isn’t what it should be, but one assumes that will get sorted for future shipments and shouldn’t cloud the fact that, even as things stand, the GLXE-6000/RSB is a very desirable instrument capable of delivering a convincing palette of unplugged and electro sounds, along with good, picker-friendly handling.
The instrument’s plush, though happily not tackily flash, and presentation counts in its favour too, justifying its status as Crafter’s top-range grand auditorium.

Jet City JCA100H
Thursday, July 29th, 2010
During the LA-based guitar boom of the late ’80s/early ’90s, Mike Soldano’s namesake amps were everywhere. The SLO-100 is arguably his most iconic design, a high-octane monster that allows tonehounds with enough cash to fill their nostrils with the stench of free-range valve distortion.
The Soldano sound wasn’t available on a budget… until now.
Late last year, Soldano cofounded Jet City Amplification with an aim to build affordable valve amps, and Jet City has just touched down in the UK with its flagship offering, the JCA100H.
This model features the same circuit design and identically labelled controls as the SLO-100, giving you two channels (Normal and Overdrive), a shared three-band EQ section and a master Presence control.
The preamp uses four 12AX7 valves, with four 6L6s in the power stage delivering 100 watts of power. There’s also an extra 12AX7 that buffers the effects loop.
The Normal (clean) channel is bright, but with a slight scoop to the mid range thanks to the 6L6 valves, and the preamp stays clean until you push it to around halfway.
Try some neck position single-coils for that classic woody blues sound, and add some gain and presence for some Gaslight Anthem style chiming open strings. Boosting the preamp further takes you into chunky classic rock rhythm territory.
The Overdrive channel picks it up from here, and there’s a noticeable kick that results in an overall ‘larger’ sound. We’re talking fat-ass, harmonically rich powerchords and just enough gain to make hammer-on and pull-offs lead lines easy without becoming fizzy.
There are a couple of niggles, though. Channel switching is handled exclusively by the included footswitch, with no control on the panel. This might seem like a moot point, but if you lose or forget the footswitch you’ll be stuck in whichever channel you left the amp on until you get another footswitch.
The other point is that there’s no onboard reverb. OK, so it’s not a huge problem but similarly priced competing products on the market have kept it in.
Soldano’s input here carries a hefty chunk of credibility and quality. And let’s be honest, only a numpty leaves gear behind at gigs, and the lack of reverb won’t be a problem for many.
Jet City’s mantra is “100% tube tone; 0% Bull****”, and, interestingly, we found ourselves concentrating less on tweaking the tone controls and more on just playing the damn thing – which is always a good sign.

Soundtoys Juice: analog channel preview
Friday, June 25th, 2010
Expect more analog-inspired bytes from Soundtoys soon. They’re working on Juice, an analog channel plug-in (the interface shown here is just the first prototype). Juice is gonna be definitely subtler than its older brother, Decapitator.
In their words “…Our plan for Juice is to develop 4 to 6 entirely new input models based on console input channels and/or mic pres, running at normal to slightly driven levels (just the preamp part, not the EQ… yet.)”.
It will be interesting to compare Juice with the good old McDSP Analog Channel (ProTools only ’til now, it should be available to Au users in the next weeks, at last!).
Given Soundtoys’ reputation, expectations are definitely high. We’ll keep you updated. They’re known to be perfectionist though, you’ve been warned…

Studio Devil Amp Modeler Pro
Monday, January 25th, 2010
Studio Devil’s Amp Modeller Pro is its most ambitious product to date. It includes not only valve preamp and power amp modelling, but also four stompbox-style effects, impulse-based cabinet emulations, a 7-band graphic EQ, 1-band parametric EQ, compressor, gate, echo, reverb and wah-wah.
Currently the software is in VST and AU formats (it doesn’t run standalone), with RTAS support in the pipeline.
Studio Devil is keen to point out that Amp Modeller Pro uses its own patented modelling technology to replicate the behaviour of hardware preamp valves. There are tone controls (bass, mid, treble and presence) and a modelled power amp stage (Tube Class A, Class AB and FET). Aiding sound quality are 64-bit processing and, with the Hi-Fi switch engaged, 192kHz internal upsampling.
In detail
Unusually for a modern amp plug-in, AMP has a single-page interface, and with the exception of its tuner (which appears in a pop-up window), all controls are crammed into quite a small window.
Our first impression of this was that it’s a little crowded, but in its defence, you won’t get lost hunting across multiple pages, and once you’ve learnt where everything is, it’s quite immediate.
It’s worth noting that AMP doesn’t enable you to use multi-amp setups, and it doesn’t feature variable mic positioning (although its cab options provide different mic positions), nor does it offer any ‘tone’ pedals (ie, overdrive, distortion, etc). However, you can assign MIDI CCs to all of its parameters (including the Wah-Wah Filter), and its cabinet impulse processor accepts third-party WAV and AIFF impulses. Indeed, the program’s stock cabinet impulse library is bolstered by a demo set from ReCabinet to whet your appetite, and a further selection of bonus cabs.
AMP’s controls are, for the most part, self-explanatory and the division of the GUI between the top half (amp, cabinet and EQ) and the bottom half (effects, compressor and gate) makes perfect sense. However, there are a few controls that merit particular mention.
First up, five of the effects (Chorus, Flanger, Phaser, Tremolo and Echo) and the EQ section can each be placed before the amp (stompbox-style) or after (like studio effects). This influences the sound considerably, and effects placed after the preamp become stereo, too.
The effects are all of good quality, and while they don’t have zillions of controls, there’s enough there for you to dial in a range of sounds. For instance, the Echo effect’s Style control takes the sound from ‘analogue’ (low-pass filter) to ‘tape’ (band-pass) on through to digital delay (no filtering).
Amp Modeler Pro is the work of New York DSP engineer Marc Gallo, who’s made it his personal mission to produce CPU-efficient models of real-world valve circuits. Gallo reckons that his work has resulted in a plug-in that captures the non-linear behaviour of both the frequency and dynamics of hardware guitar preamps, and we’re inclined to agree with him.
