At these prices? Dave Petersen is impressed Blackstar Artisan 30 & Artisan 15 S ince Blackstar introduced these, their first models, at the London Guitar Show last summer, they’ve been attracting a healthy amount of interest. Designers Bruce Keir and Ian Robinson are the team behind some of Marshall’s more recent successes, and Northampton-based Blackstar aims to offer hand-wired gear at reasonable cost, with classic design, high component/ assembly quality, and exceptional sound. Design and distribution is UK-based, with manufacture carried out in South Korea. Both amps have a solid, purposeful air with a traditional simplicity in their layout. Laurel-leaf linework on etched black control panels, knurled knobs, industrial-weight toggle switches, wide radius contouring and faultless burgundy cabinet covering give an impression of quality. As on a Marshall, the chassis is fixed at eight points to the rear panel and is carried on 18mm battens, as in the classic Bluesbreaker and 20W 1974 Pure Simplicity: the 15 has two channels with Volume and Tone, plus a 1/3 power switch 70 September 08 – Guitar & Bass FACTFILE ARTISAN 15 & ARTISAN 30 Description: 15W & 30W valve combos. Built in Korea Artisan 15 specs: one EZ81, two EL84s, two ECC83s and one EF86 valve. 12" Celestion G12M speaker. Control panel: Channel 1 input jacks (paired); Volume, Tone. Channel 2 Input jacks (paired); Volume, Tone; Pilot; 5W/15W output selector; Standby; Mains. Rear panel: IEC mains socket; mains fuse; HT fuse; output selector 4-816 ohms; paired speaker jacks. Comes with slipcover Dimensions: 62cm wide, 52cm high, 24cm deep. Weight: 23kg/50lb RRP: £799 All Blackstar amplifiers come fitted with Electro-Harmonix valves as standard This Northampton-based company aims to offer high quality handwired gear with classic design and exceptional sound combos. In both Artisans the frame is of 18mm ply with 12mm front and rear panels, while the chassis is of 1.5mm plated steel with welded corners. It’s the kind of solid quality you might expect from a no-expense-spared handbuilt. Both amps are cathode-bias class A EL84-driven designs with valve rectifiers and choke-filtered HT supplies, and Electro-Harmonix valves fitted as standard. Circuits are fairly conventional, with a mix of early Vox and Marshall influences. In both amps, one preamp channel is fitted with an EF86 pentode, the other with a 12AX7 twin triode. The 30’s EF86 channel emulates the old AC15 with its switched bass contour and single tone control, while its 12AX7 channel is wired with a three-band tone stack, a bright/warm Voice selector, and Gain and Volume controls. The Artisan 15 has nofrills Volume and Tone in both channels. Both amps feature a low-power switch that cuts the output from one phase of the push-pull driver, effectively changing the amp from push-pull to a single- Artisan 30 specs: one GZ34, four EL84s, three ECC83s and one EF86 valve.

Handwiring, EL84s, tremolo and benchmark tone, but at a UK-built price RRP: £975 ender but leaving the output stage bias currents at normal levels, avoiding rises in supply voltage that might lead to overheating. Circuitry is laid out on a single long pax board using underwired turret-tags rather like on early Marshalls. Wiring runs are short, which suggests a methodically-designed layout and benefits transient pulse response. Switches and ceramic valveholders are of good quality, and very few components are fitted off-board in a way that might be vulnerable to vibration. SOUNDS The valve rectifiers ensure a fuss-free warm-up, but the cautious may prefer to use the Standby switch as well. The amps run quietly with zero Volume settings although the preamp stages aren’t gated. With half Volume white noise increases, but even with single-coils this setting takes us near the amps’ limits in clean mode. A Strat in the 30’s Channel 1 has a clear, chimey response at full gig levels, while with the SG we’re already edging into saturation, and the Volume has to go down to around 3/10 to stay clean. There’s a mix of clarity and edge with both guitars, but the SG benefits from a rolled-off Bass switch setting to keep full The Artisan 30 has one Voxy EF84 channel and one 12AX7 channel with three tone controls and a Voice selector 72 September 08 – Guitar & Bass The tonality is best-of-British, but the jangling complexity of the harmonics suggests a high-end American EL84 amp chords from flapping out. It’s tempting to describe the tonality as best-of-British, but the jangling complexity of the harmonics has a suggestion of high–end American EL84-driven amps. In the 15, the EF86 channel (2) sounds similar, so the pentode gives both amps a more lively and open sound; indeed, the actual 12AX7 channels sound more reined-in and docile. Some players will prefer that, because it sounds more ‘older amp’, and it’s nice to have the choice. Channel 2 of the 30 has a more conventional gain and tone structure, and will sound familiar to users of Hiwatts and early Marshalls. Beyond the clean limit – gig-worthy in either amp – the saturated sound is smooth and open, with a clear grittiness and little tendency to add undertones. The SG blends effortlessly into octave-up overtones and the ‘sweet spot’ balance of 2nd and 3rd harmonics is very easy to find, although the 30’s hard-hitting volume level may be too much for this at anything but big gigs – even the most energetic drummer will have some serious competition. Pushing the Gain against the Master on the 30’s Channel 2 to get earlier distortion doesn’t get the same result – in fact it doesn’t seem to overdrive much with single-coils at all, and, like the older Hiwatts, really needs humbuckers for this. There’s also a tendency to undertoning, although the bright Voice selection helps keep it tidier. By contrast, the low-power selection is good for rehearsal and recording, retaining clarity but saturating nicely at more practical levels. The 10W setting on the Artisan 30 is still pretty loud, so if you’re doing pub/club work, the 15 may be easier on your back and your finances. VERDICT Both these amps are among the best in their classes, regardless of price. The lack of footswitching or an effects loop may seem over-simple to those used to more elaborate amps, but the direct wiring and signal paths are an important part of that harmonically rich, punchy sound that you get so much of for your money.
