KATANA-100: FX LOOP SEND/RETURN SIGNAL CHAIN LOCATION
The KATANA-100 FX Loop Send/Return is located within the AMPLIFIER EQUALIZER section of the KATANA EFFECTS CHAIN. This can be accessed and changed with the BOSS TONE STUDIO SOFTWARE. Options for CHAIN 1, CHAIN 2 and CHAIN 3 are available for selection.
If you are using a LOOPER pedal (ie. BOSS RC-3/30/300) with the KATANA, use CHAIN 3 for the best functionality, REVERB will still be the ending effect but can be set to zero.
