Using a Digitech Trio+ with a Boss Katana 100
« on: December 01, 2021, 11:53:47 am »
I've been asked if I can post the cabling to support using the Digitech Trio+ with the Boss Katana 100 series amps, as I have previously stated that this was "non obvious".

Note that, whilst this is aimed at the Katana 100, it should work for any amp which has an effects loop, modelling or otherwise, although it's most useful for modelling amps.

Also, this requires an amp with an FX loop, so this won't work for the Katana 50, for example.

Note that rule of thumb to use when using a looper with effects is: record the effect, don't effect the recording.

In other words the recorded loop should have the effects added to it. On playback, no further effects should be added to the recorded loop.

The background for this is the Digitech Trio+ has an effect loop (send and return) which is designed, primarily, for connecting external FX pedals so that they can be used in conjunction with the onboard looper. The manual diagram shows this (I have highlighted the FX loop):



This is fairly straightforward for external pedals, but when using the internal pedals on the Boss Katana 100, a different wiring scheme is required. This wiring scheme includes the pre-amp and fx sections for the Katana into the Digitech FX loop:



In case this image is not clear, the connections are as follows:

Trio+Katana
FX SENDINPUT
FX RETURNEFFECT LOOP SEND
AMP OUTEFFECT LOOP RETURN

The guitar connects to the Guitar in as normal.
 
It is also important to make sure that the Katana chain is set up correctly. Primarily, you want to make sure that the Send/Return is configured to be "POST REV" so that it appears after the REVERB section and, hence, after all of the other effects:



Cheers,

Keith

This is a good diagram I found helpful.

Thanks for posting! It helps confirm I am on the right path, but I need to check my chain, I am not sure I have that part right.

Excellent write up there Keith and I guess the key points are that in your description both Drums and Guitar are going out through to the amp. Your approach also avoids the Drums having the effects applied to them BUT also works quite happily if you have the drums going out of the MIXER output.
