Erica Synths Fusion Box Multi Analogue Effects Unit

Erica Synths Fusionbox is a 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.

Features:
Delay and Flanger effects
Vintage Ensemble Stereo effect
Tube overdrive in the delay output and feedback path
FX send/receive connector
Footswitch connector
2 BBD chips (1024 and 4096 stages)
Passive Lowpass filter for extreme subbass sound
Fusion Box lowpass filtering is fully adjustable from none to extreme for a really deep bass sound. A special feature, not found in other contemporary stompboxes or effect units, is the Vintage Stereo Ensemble.

The 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 the other. This gives it the distinct and unique moving character, different from 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 this case and 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.
