British Blizzard dual overdrive


Achieve the boosted ‘Blizzard of Nails’ British tones that influenced many guitarists and generations with Breakthru. Two channels of mid-rangy overdrive that will upgrade your tone with a new dimension of punch and dynamics from Indie or Blues to Hard Rock tones.

Designed with the same internal structure as a classic 2x12 British combo amplifier, Breakthru packs a Normal channel with a gain control, a Bright channel with a gain control and two bands EQ and a master section with a phase-split treble damping control and a global volume.

Thanks to its three-way VRM switch, you can use Breakthru as a Vintage (V) or Modern (M) pedal connected to the input of your amplifier, or as a preamp (R) connected to a power amp or the return jack of an effects loop.

Satisfying even the most exquisite ears, Breakthru is built one by one using high quality components, adjusting each gain stage so the sound is optimal in every unit.

Equipped with SE2 technology, it can be used to record through any audio interface. Just open your favorite DAW and load the impulse responses, exclusively designed for Breakthru, to turn it into a real British amplifier that will take your recordings to the next level.

If you want a robust, versatile and exclusive dual overdrive, get your Breakthru.
