Another Jaon Sadites video below regarding Tonex and HX Stomp. He explains in the beginning that he uses a separate Send and Return block in the HX Stomp rather than one FX Loop block. The reason is that the levels need to be set different on each block for best results. Now, I know how to hook my Tonex One into my HX Stomp and set the levels proper.
(Edit) Apparently, the way to do this is set two blocks, one L Send Instrument and two R Return Line, in global settings. I’ll give this a try tomorrow. Then, I’ll crank it up loud and switch the R Return between Instrument and Line to see how much difference this makes.
(Edit) I tried this at low voiume. I switched between Return Instrument and Return Line. I could not hear any difference. I’ll have to give that a try again tomorrow at loud volume to see what I can her and report back.
(Edit) I just realized that Jason’s video is regarding ToneX not ToneX One. Mark, this may be the answer to why you had to bail on using your full size ToneX pedal in the loop of the HX Stomp. The full size ToneX has instrument level input and line level output. So, you have to build two blocks into HX Stomp. First block L Send - Instrument. Second block R Return - Line. However, the ToneX One may have Instrument level output. If so that Return would be set to instrument which can be accomplished with a single fx block.
