Our Verdict

Existing users might feel a little short- changed, but the definitive virtual Tube- Techs look and sound better than ever.

Pros

  • CL 1B compressor is so, so good.
  • Dual EQ configuration makes sense.
  • All three sound fantastic.

Cons

  • Intrusive preset manager.
  • EQs can’t be reordered.

Almost a decade after the launch of its trio of native Tube-Tech valve EQ and compressor emulations, Softube has collectively upgraded and tweaked them to take advantage of today’s much more powerful Macs and PCs, and their higher-spec displays, and thrown in a couple of completely new features to sweeten the upgrade deal. 

As was the case with its predecessor, Tube- Tech Complete Collection Mk II centres on plugin (VST/AU/AAX) virtualisations of Tube- Tech’s PE 1C and ME EQs, and the CL 1B compressor.

The first and most obvious of the bigger changes, however, is that the EQs now come combined in a single plugin rather than being provided as two separate ones. As before, you can buy the MK II plugins individually, bundled with their older ‘legacy’ versions as the Tube-Tech EQ Collection ($199) and Compressor Collection ($299); but grabbing the full Tube-Tech Complete Collection Mk II not only lowers the price of both together but also nets you the Tube-Tech Classic Channel, which unifies the three Mk II processors in a single channel strip-style plugin. 

The second obvious change for Mk II is in the graphics department. The whole lot has been given the Retina/Hi-DPI treatment, and made much bigger for easier mousing, while the dual EQ simply stacks the two previous plugins on top of each other. The pointless brown borders and overly realistic ‘lighting’ on the stepped knobs have been ditched, too, and that, thankfully, gives the GUIs a cleaner, more contemporary look. 

Existing owners of the Complete Collection can upgrade for $99, incidentally, and for those unfamiliar with the original Tube-Tech hardware, a quick history lesson can be found in On the Tube-Tech. 

PE1C and ME 1B EQ 

Just like the real Tube-Tech boxes (and the Pultec originals before them) the idea behind the PE 1C and ME 1B ‘passive’ EQs has generally always been to use them in series, with PE 1C handling high and low shelving and mid-range boost, and ME 1B following up with high and low boost, and its sweepable mid-range ‘Dip’ bell. It’s perfectly reasonable, then, that Softube has stuck them together in a single plugin, with each section including its own power button, facilitating individual usage. 

Strangely, though, the two EQs can’t be reordered, so the only way to run ME 1B before PE 1C (unconventional, we know) is to load two plugins and bypass one of the EQs in each. Not a great chore, but a routing switch would be preferable nonetheless. 

On the Tube-Tech

Danish manufacturer Lydkraft has been building pro audio equipment since the 70s, but it wasn’t until the mid-80s that the Tube-Tech brand for which they’re now primarily known came into being, with the release of a pair of vintage EQ clones and a compressor inspired by another classic box. In 1991, the three were updated to house the transformers and tubes on printed circuit boards, and they’ve remained true to that design ever since, as the PE 1C, ME 1B and CL 1B. 

The PE 1C and ME 1B are essentially remakes of Pultec’s revered EQP- 1A and MEQ-5 passive tube EQs. The PE 1C is all but indistinguishable from the American original, while the ME 1B broadens the MEQ-5’s three frequency bands for an even smoother response. The CL 1B, meanwhile, has become a legend in its own right, standing as a similar but more modern sounding, controllable and thus versatile alternative to the Teletronix LA-2A compressor/limiter, and selling more units than anything else in the Tube- Tech catalogue. 

Happily, Softube’s virtual versions of these incredible but prohibitively expensive processors were developed in conjunction with Tube-Tech themselves, so their authenticity certainly isn’t in doubt. 

Softube’s PE 1C sounded the business already, and with its improved engine, Mk II feels perhaps a touch silkier, but it’s a very subtle difference, if any. Dialling in the ‘low-end trick’ (boosting and attenuating the Low Frequency band simultaneously) is a good test of any EQP- 1A or derivative thereof, and PE 1C Mk II handles with aplomb, bringing the best out in kick drums and basses. Again, though, the difference between it and Mk I is anything but profound - upgraders be aware. 

It’s the same story with ME 1B, which models the Low and High Peak filters, and all-important overlapping 0.2-7kHz bell-shaped cut filter of the real thing beautifully. 

Softube claims that nothing major has been changed with the EQs apart from their repackaging as a single plugin, which may have a minor effect on the sound. Ultimately, then, these are the same wonderfully musical, warm and natural sounding Tube-Tech EQs we’ve known and loved since 2010. 

CL 1B and Classic Channel 

While the two EQs are basically unchanged, the LA-2A-inspired CL 1B opto compressor has been rebuilt from scratch, and now includes a sidechain low-cut filter (80 or 220Hz), and a dry/ wet mix control for parallel processing. The remaining parameters are unchanged, including the option of Fixed or Manual Attack and Release settings (the former no longer paralysing the two knobs, confusingly), or a combination of both, which simplifies timing adjustment; compression Ratios up to 10:1; and an external sidechain input. 

With its fast attack and smooth release, and rich, colourful sound, this has long been one of the best software compressors that money can buy for vocals, basses, guitars and the (largely non-percussive) like, but Mk II is noticeably smoother, punchier and more responsive, and less prone to distortion with fast attack times. It’s fabulous. 

Finally, Classic Channel piles all three processors up in a single plugin, giving you the further option to place the EQs pre or post compression, a choice of left/right or mid/side processing, and the ability to unlink L/M and R/S for independent parameter adjustment of each. Handy, indeed. 

Soft sell 

While CL 1B is awkwardly expensive on its own, we’d describe Tube-Tech Complete Collection Mk II as reasonable value, since the quality of all four plugins is truly exceptional. However, we do think the upgrades from the previous versions should be free, as while the new CL 1B modelling and mix control, and stereo configuration options are great, they’re not gamechanging. 

Economics aside (and disregarding Softube’s intrusive, overblown new preset browser), this is a fantastic set of vintage-style, ‘tube’-powered mixing effects, easy to work with and fair dripping with musicality and analogue soul.
