I finally got one of these boards made and installed after a couple of revisions. The input section of the send is jumperable for phase reversal, and the pot controls the input level in the return section. If ypu want to match the sounds of your old delay, chorus or other stomp box pedals to the units in the POD, this mod allows you do so with comparative ease. It also works a treat for playing along with an external band track from an IPOD, DAW or similar. Even a looper with a separate effects setup is another possibility. Many thanks to Miroslav for his advice and assistance.

All good so far. This simple mod works great with either my IPOD, BOSS MicroBr or Galaxy Tab3. Gavan.

Hi Miroslav, Pleased to tell you that putting 1k resistors between pin 1/7 (U18), and 3/6 (master volume) has little change in volume.
-
Thank you very much for your help. I have design PCB to fit in shell of XT near output control
-
So no need a capacitor between pin1 (or 7) and the 1k resistor in the return circuit?
-
So leave R1 out. Do I still use C1?

Is it better to take signal from Input Jack and use IC buffer ? ... I try to describe better with circuit diagram #1 - AuxSend-2.jpg: Perhaps circuit diagram #2 - AuxReturn-2.jpg explain idea better:

Thanks for clarifying the resistors. I thought that was probably where you had patched the H/P in but I wanted to be sure. I had thought of taking the effect send off the junction of R20, R25 and Pin1 of the OPA2134 which seems to be the logical point of patching headphones in. I know that phase shift may be a problem but I will only find that out by trial and error so I'll see when I get to that stage. I was thinking of feeding the returns back in at pins 3 & 6 of the master volume. I have 2 of these units so I was only going to modify one of them. cheers.

Hi Bill, I had already tried that type of approach but the basic idea is/was to have the aux send/return as a main integral part of the POD's built in circuitry rather than try and achieve the result using an external device to mix the two separate signal lines. cheers

I would like to patch in an FX Loop or AUX Send & Return into my POD XT taking the signal out after the guitar input and feed it back in just before the output so it bypasses any of the DSP effects. So far I have these 2 circuit ideas with a small PCB already basically designed. However I'm not 100% sure where to patch them in.

Thanks Miroslav, It is on it's way

I received your email so thank you very much for your help. There was this topic question on this forum: http://line6.com/support/topic/10543-pod-20-auxiliary-input-mod/ The reply by Miroslav was very useful but resistors R92 & R94 in his answer are for the POD 2.0. Without the schematic for this model I cannot be sure just where he is patching into the headphone out. Do you possibly have the section of the diagram for the POD 2.0 showing this modification or can you tell me which resistors would be the relative ones in the XT model?
-
If you have a schematic you can send it to my email address: :tarahall1950@gmail.com" thanks

Although I now have a POD HD500, I still really like my POD XTs (I have 2 of them). I would like to patch in an FX Loop or AUX Send & Return into my POD XT taking the signal out after the guitar input and feed it back in just before the output so it bypasses any of the DSP effects. Has anyone done this and/or are there any schematics for the POD XT anywhere?

Pod 2.0 auxiliary input mod
tarahall replied to jegtar's topic in POD 2.0, POD XT, Pocket POD, FloorPODs
R92 & R94 are for the POD 2.0. Do you know what the equivalents are for the POD XT? I wanted to patch in an FX Loop or AUX Send & Return into my POD XT after the guitar input and feed it back in before the output without using any of the built in digital effects. Has anyone done this and/or are there any schematics for the POD XT anywhere?
