FX Loop tone quality loss

Nano Cortex
1

I’m getting tone suck when inserting the NC into the FX loop of either my GT-1000 Core or QC (just using to test).

With all cab sims, amps, reverbs, fx, etc. turned off on either host device (just the fx loop block active), the output (host headphone) sounds different/poor when compared to the headphone output from the Nano. It sounds like the already reverb’d signal is being sent through a second reverb.

I have good power (Cioks 9v 660mA), good cables, no ground noise/hum, and am experienced using the FX loops. I initially thought I was making a mistake setting it up with the GT1KC, but then tried it with the QC and it does exactly the same thing. It seems like the Nano’s 1L out is not outputting a clean signal.

I am in contact with support. Have any of you guys noticed tone issues when connecting the NC to a multifx unit through an FX loop - GT1K, HX Stomp, etc…?

i’m going to try this sooner or later, since i also want to put it in the loop of my stomp :ok_hand:

Any updates? I’d love to hear more about how you’re setting the Nano up to work in your Stomp’s FX loop and how well it meets your expectations

Yeah, I got it working with the GT1KC with no sound quality loss. I don’t have a HX Stomp anymore to try out.

The way they show to connect it in the manual (mono) definitely didn’t work right when placed in a loop. Connected in stereo it was better, but I can’t be bothered with the extra cabling and don’t care about stereo, so I only use the amp capture block.

Now I can freely place the amp wherever I want in the chain and use whatever pre/post FX and cabsim I want.

Today I tried to connect my Electro Harmonix Micro Synth on FX Loop of my QC in order to blend its mix with expression pedal as much as I want. However there is a problem. Micro synth does not read the input signal coming to it from Send of QC well enough as it detects it when guitar is inserted directly to Micro Synth. Especially when using neck pickup the detection of signal by the pedal is too poor and the sound is crippled. All the levels of FX loop are on ZERO. I think the direct connection impedance of guitar and the send levels differ which is why the pedal’s recognition of the voltage is different. Any suggestions?

P.S. As I remember there should be a a gate knob inside the microsynth housing. But I haven’t tried to work on it yet.

I solved the problem. FX Send level of QC is to much. So It clips Micro Synth internally which is why EHX cuts the signal. I dropped Send level to -12 and raised Return level to +12. Problem solved. Very smooth and clean sound on FX Loop with EHX Micro Synth.
