Integrating an external looper makes "flangery" sound

[slowjogg]

Hi folks,

presumably a stupid and at least a beginner question.

I'd like to use my external looper (JamMan Streo) instead of the built-in one and therefore have put a Send1 and a Return1 'box' at the end of my signal chain. Leaving both untouched makes the guitar sound as if a flanger is part of the signal chain (though it isn't - and I don't like flangers that much). Reducing the output-level more and more weakens this effect but simultaneously reduces the output volume.

Are there any settings (or workarounds) I can apply to make the guitar sound as it does without the external loop?

Best regards,

slowjogg

You're getting phasing/comb filtering because the Send block has a Dry Thru parameter, and by default, it's set to 100. So you have two dry path running in parallel, and the one running through your looper is lagging behind and slightly out of phase with the one running through the Helix. If you set the Dry Thru parameter to 0, that will solve it. Better yet, there's no need to use separate Send and Return blocks. Just use a single FX Loop block. The Mix parameter in the FX Loop block does essentially the same thing as the Dry Thru parameter in the Send block, but it's set to 0 by default.

Thank you very, very much. You made my day!!!
