A big step forward in the Darkglass family
daryodolls, 14.04.2018
Having owned most of Darkglass products, I must say that this last update is a big leap forward, especially concerning the cabinet emulation. The basic pedal is pretty much the same as the B7K v1 (check previous reviews of B7K for basic infos), the headphone output is a nice addition but the real game changer is the cabinet emulation. This is done by adding (first time ever for Darkglass) a digital processing: somebody might complain about it, but it doesn't sound digital at all and there is no perceivable lag. It is simply done in a clever way, and it dramatically expand the sonic possibilities of the pedal. You will simply want the cabinet emulation always on, and the small editing to de done on the PC is so easy that it's a no brainer: just browse through some 10 cabinets, listen to them and choose the one you like most. All IR cabinets loaded on the Darkglass Suite are proprietary, and they all sound very good, for rock and metal tones you don't need anything else. The good news is that some of the are able to make the B7K v2 sound more "mellow", which was very difficult to achieve with B7K v1: now some classic rock tones are possible, still retaining the Darkglass definition and grit. This pedal has become my new Swiss knife, it's always in my gig bag both as a main rig or backup. The IR cabinets are such a great advantage that it's worth the upgrade, just try it and you won't go back!

A jewel, wonderful pedal
Frank Iván , 26.12.2018
I already knew the Darkglass products, because I had a Preamp B7K and I am delighted with it, but in this case it is wonderful.

Pros:

You can separate the equalizations and simply apply the distortion to give wax.

The function of injection box is unbeatable, clean and a tremendous cabinet function, when you record at home with the card you get sounds really achieved as if you were with the screen. It is also completely versatile from the Suite that you download from the page, through usb fully configurable in my case in apple goes perfectly. Being able to use different microphones and cones. I think live works really well without the need for an ampli.

I have to emphasize the clean sound it creates.

The distortion as always is tremendous, forceful and very versatile.

Working at 9v you can include it in the power supply of the pedalboard without problems.

It is a good size, although quite compact, it occupies little space for everything it offers.

On the cons, the only thing I can say is the price, because it is high, but it is worth it. In everything else it is outstanding.

I have used it with Sandberg California VM5, Warwick Rockstar 5, Cort Artisan 5 and the truth is great with everyone, respecting the sound of the instrument.

The truth if you are looking for a versatile pedal, many sounds, blunt distortions and you need a good interface to get your bass sound at home this is your pedal. Perhaps at home in production is where I use it the most.
