Hi all, I have just experienced a new ( for me) way to use my helix. It's really a great piece of gear, but my old and beloved tube amps were missing me. So, I tried this chain: gtr into tube amp, speaker output of the amp into load box, load output into return of send/return1 of the helix, then a couple of blocks such as IR, reverb, etc. The result is amazing. Then, in order to be able to use some fx before amp, I tried to plug the guitar into helix first, then send the signal to tube amp input via a send/return output of helix, back to Helix via return of the same send/return, and all I get is squealing... Any idea about what I'm doing wrong ???
Tried with different amps and got the same problem... :(
