FusionBox
Thank you for ordering erica SynThS fuSionbox!
Erica Synths Fusionbox is distinct multifunctional analogue effects unit that combines BBD chip based
effects – delay, flanger, chorus – with an adjustable 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.
