Sonicake Matribox 2 (Octaver) vs TC Electronic Sub'N'Up Mini Octaver | Guitar 

Sonicake Matribox 2 is a multi-effects Guitar and Bass pedalboard that allows you to have a totally customizable effects loop to which, if desired, you can add your own analog pedals. I compared its integrated octaver with the analogic pedal TC Electronic Sub'N'Up Mini Octaver.
If you don't hear the sound from the external pedal, make sure you remember to manage send and return levels and mix in the settings.
