Erica Synths Fusionbox is distinct multifunctional analogue effects unit that combines BBD chip based effects – delay, flanger, chorus – with tube overdrive in the delay output and feedback path for extra thickness of sound. For more flexibility, lowpass filtering is fully adjustable from none to extreme for really deep bass sound. Special feature, not found in other contemporary stompboxes or effect units, is Vintage Stereo Ensemble.
Vintage Stereo Ensemble provides the classic “stereo ensemble” effect, found on many vintage synthesizers from almost any brand and make. In stereo ensemble effect, the delayed, processed and filtered sound is added back to the dry (mono) audio with inverted phase for one channel, and direct phase in other. This gives it the distinct and unique moving character, different than that obtained with chorus effects. However, use of inverted phase in stereo field also adds certain peculiarities to watch out for. For example, when such stereo audio is played back on an older “surround” decoding sound system, ensemble effect sound may move to the rear sound channel. Also, if the output gets mixed back to mono, the effect may disappear. This also applies to mono subwoofer systems, or speakers that are placed too close. This is normal, and occurs with any similar vintage stereo ensemble processing. In case if such oddities are undesirable, to avoid mono mixing issues, you can choose to use only one of the output channels, or use two separate ensemble processors for left and right channels.
Fusionbox has adjustable input gain, therefore it works with various sound sources – guitars, units with line level signals (synthesizers, grooveboxes, etc.) and modular synths. Footswitch allows to switch on or bypass effects making Fusionbox ideal for guitar players.
