Thank you for ordering erica SynThS fuSionbox!
Erica Synths Fusionbox is distinct multifunctional analogue eects unit that combines BBD chip based 
eects – delay, anger, chorus – with an adjustable tube overdrive in the delay output and feedback path 
for extra thickness of sound. For more exibility, lowpass ltering is fully adjustable from none to extreme 
for really deep bass sound. Special feature, not found in other contemporary stompboxes or eect units, is 
Vintage Stereo Ensemble.
 
Vintage Stereo Ensemble provides the classic “stereo ensemble” eect, found on many vintage synthesizers from almost any brand 
and make. In stereo ensemble eect, the delayed, processed and ltered 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, dierent than that obtained 
with chorus eects. However, use of  inverted phase in stereo eld 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 eect sound may move to the 
rear sound channel. Also, if the output gets mixed back to mono, the eect 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 le 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 eects making Fusionbox ideal 
for guitar players.
