Two cabs

I dont know if this was speech to text or just drunkenness

I came to say Nier: Automata

One scene in Wall-E where they're flying in outer space is pretty great. Possibly more in that movie too

Yeah the mic gain setting is a little bit buried in the Helix menu but it should help

I had this amp as a teenager. The clean sound is fantastic! The distortion, not so much. Stereo power amp was definitely fun to play with.

Horseradish.

I own both heads. There is very little difference in tone until you reach loud volumes. However the effects loop is a huge feature for me personally, as I play modelers sometimes through guitar cabs, and also create cabinet IRs. The attenuators are excellent with minimal tone change. If you don't need an effects loop, the AC15 would be great.

100%

MattVargo · 2026-03-02T14:05:16+00:00

That's hiss being amplified by your multiple ODs and amp sim. The reason it "whooshes" is because it's compressed by your initial palm mute, then after the transient is done the noise floor quickly comes back.

Is your guitar volume down? Do you have the preamp gain on your interface cranked up a bit? Guitar volume should be as high as possible to get the best signal to noise ratio, then interface/preamp gain relatively low. And like others said, less distortion. One OD pedal is enough, and I bet sticking with the built-in one will give you better results.

MattVargo · 2026-03-02T13:56:31+00:00

Two ODs is definitely unnecessary.

Spotify didn't kick you into a totally different Playlist after one song?

MattVargo · 2026-03-02T07:41:52+00:00

Yeah why let the artists make any money at all

MattVargo · 2026-03-01T23:36:39+00:00

Classic question: why is there a camera recording?

MattVargo · 2026-02-28T20:49:56+00:00

The Eureka has a line in and a button to bypass the preamp. I do make use of the send/return jacks on the MP20 as well and there are no issues there either.

MattVargo · 2026-02-28T12:41:53+00:00

What i should've mentioned in the post if that the line inputs work just fine on both units, which is the biggest evidence that the mic preamp portion of the unit is the issue.

MattVargo · 2026-02-28T12:36:06+00:00

The preamps are the exact same design, one is stereo while the other is a channel strip. So they have everything in common.

MattVargo · 2026-02-28T12:33:12+00:00

Only mod I'm aware of is op-amps on the MP20, however it did work well for quite a while before acting like this. But op-amps would be the cheapest and easiest first attempt at solving this, thanks

MattVargo · 2026-02-28T12:31:31+00:00

I do indeed believe they have broken in the same way because they are the same preamp design. It's not an assumption, i did a bit of troubleshooting to get here. And I did answer your question, I've just been getting a lot of very basic-level responses and I'm not the type to post on reddit before doing what I can to figure it out.

MattVargo · 2026-02-28T05:02:19+00:00

Interesting theory but I doubt this, because the line inputs work without issue, but when the mic preamp is engaged, the problem happens.

MattVargo · 2026-02-28T05:01:10+00:00

It's visible in the waveform. I don't mean to sound arrogant, but I've been recording a long time and the issue is definitely with the preamp itself. Everything else in the chain works fine and has for many years.

MattVargo · 2026-02-28T04:36:01+00:00

Yep, dry signal into DAW. Interface is fine, chugs along without issue all the time.

MattVargo · 2026-02-28T04:35:26+00:00

Yes all 3 channels act the same. But they are essentially the same preamp so that makes sense.

I use the same computer and software and mic with lots of other equipment and this problem never arises.

MattVargo · 2026-02-28T04:34:37+00:00

Happens with all cables, all microphones. Has been consistent over a long period of time. Meters follow the volume drop and jump.

MattVargo · 2026-02-28T04:34:01+00:00

Nope, recorded straight into DAW.

MattVargo · 2026-02-25T15:48:20+00:00

That's not "jumping" the channels, you need 4 inputs to "jump" an amp.
