The Walrus Audio Warhorn Overdrive could well be the perfect mid-range, transparent overdrive pedal for you. We hear transparent a lot with Overdrives, but this idea is simply to not change your underlying tone as it adds the grit. The Warhorn certainly does that. It’s capable of not only outstanding punchy rhythm but also searing Texas Blues leads and all in between (check out the video below). And this version, for added versatility, features a toggle switch that provides two distinct flavours of clipping. The up position of the centre located switch is a more compressed, symmetrically clipped tone (think USA tones). The down position is an asymmetric, more open and altogether more organic sound (think British tones).

Overall this design has more grit to it than the famous gold pedal it’s emulating, you know the gold one with the mythical beast astride it. And this extra grunt gives this great pedal just a bit more flexibility on your board too.

On top you’ll find a powerful set of controls covering Level, Drive, Bass and Treble. These EQ controls really provide a large range of tweaking and shaping options for your original tone; Bass to warm up those blues leads, or treble boost to make then cut through the band’s mix. Overall it’s a great mid range overdrive and one to seriously consider in your quest for the perfect overdrive.

Oh yeah, and as it’s a Walrus Audio pedal, it’s a looker too, aren’t they always. The Walrus Audio Warhorn Overdrive comes in a “prismatic gold” enclosure with white, cream and black ink. The artwork features a warrior at the front lines brandishing an intricate battle horn leading his army in a victorious battle.
