Microtubes B7K V2 Bass Overdr. : You don't need a tube amp

After a lot of consideration I got this pedal to dial in some warmth into my sound. And it really does the trick. You can go for a more aggressive sound (if that's your thing) and shape it to your heart's content. I combine my amp's EQ settings with the EQ from the B7K, then you can blend how much 'dirt' you want (basically mix the clean and distorted signal).

You can shape it to be subtle but the warmth and that classic gritty tube sound is noticeable and really lovely - you don't need a tube amp. It's also silent and feels smooth. I'm skeptical when it comes to distortion and was extra wary due to Darkglass' 'metal' reputation but the quality sound you can get from the B7K is genial. Not cheap but I think you get what you pay for.
