The name DryBell should ring at least two loud bells when it comes to respected pedals. The Vibe Machine and Unit67 are both much loved in pedaldom and are found on many discerning pedalboards. The Unit67 shares some of its tricks with the new 'The Engine' Foundation Preamp. Specifically, the Range (master) boost side. Paired with a versatile British amp-like overdrive/distortion, the Range side is capable of many things - boost to grind and everything in-between. It's a classic recipe but one rarely found in a dual pedal. The Engine takes care of that. In the classic configuration you'd see the Rangemaster before the amp. The Engine lets you switch to the other way around thanks to its 'Order' switch. That combination will truly awaken your amp (and your audience!) The Engine will do very well because it sounds great, is easy to use, and is basically 30 years of classic rock tones in a can. You need one. Yes you do..!
