Forget the clones - the Frantone Sandwich is a totally new concept in analog optical compression.  Its high performance is powered by a new optocoupler designed and manufactured by Frantone in the USA,  which controls an active attenuator circuit for ultra linear response and maximum sensitivity.  Supremely quiet with amazing fidelity, the volume levels remain constant as you increase compression with the Limit control.  Adjusting the Threshold lowers or raises the audible floor, so you get just the response you need.  With this control you can eliminate background noise or allow every nuance to shine through.  The Sandwich is the perfect choice for a very powerful compressor in a simple package.  As a bonus the panel mounted performance LED illustrates what you play and shows the compressor at work.  Watch it talk!

  Great for both bass and guitar alike.
