The Dual Dagger from Shakmat is a dual stereo filter with two filters that work in tandem for fantastic sounding and dynamic stereo filtering. It features both high and low pass filters with individual cutoff frequency and shared resonance control. The two carefully calculated inputs ensure an accurate and precise cutoff frequency. A panning control for both filters allows for offsetting the left and right frequencies for unique stereo effects. Link the two sections to turn the module in a 48dB/oct bandpass filter with independent bandwidth controls and edge resonance. The Dual Dagger delivers stereo filtering with rich and full-sounding filters and plenty of control options in a compact package.
