I've been working for a while on this rbpi5 pedalboard using NAM tested v0.1.0 on rbpi5 8gb and working pretty well and i'm pretty happy with the result 😁
Feel free to test it, it should be able to run standalone on x86 and aarm64, Ive mainly tested it in QEMU x86 and Rbpi5 with a focusrite.
Integrated with Tone3000 to download directly profile from OpenRig
Open to suggestion, features requests and issues.
Next step for me are packaged OS updates and Hardware GPIO to make it look a real pedalboard.
On perf side, on rbpi5 it boots in ~3sec, I can chain 6-7 NAM profile easily without any drops.
It baffles my mind how the M-vave Pocket Amp (probably their cheapest?) can run NAM A2 Lite native, while the budget devices from Valeton, Sonicake, Hotone, Mooer, Soran, etc can't, and have to do NAM conversion. This is even running 44.1kHz which I initially thought was one of the reasons why others have to do conversion.
Anyone have any clues what's happening here? One thing I noticed is that M-vave devices generally have higher latency, which sometimes can go up to 7-10ms while others are usually 3-5 ms. Is this a factor?
As a comparison, the Valeton GP-150, one of Valeton's more modern budget units can run NAM A2 Lite native but it uses 70% CPU so it already limits the number of effects you can use. If you want to use the full chain you have to do NAM conversion. Is it just a case of inefficient firmware or is it something else?
I honestly just feel really stupid but am I tripping that SoundShed is not very intuitive ? I can’t for the life of me just find how to simply access my folder of captures and load them. Can someone share with me a screenshot of where I can achieve this?
Just curious if anyone is using any of those IRigs on windows for live rigs. I've been using my Tonex One as an interface because the output can either be jeadphones or a Hi Z out so i can run it through all my post effect pedals and then to my ir pedal and into my tonex cabs. The coices of interfaces with a HI Z output are pretty much limited to IK Multimedia products. Problem is Tonex pedals only run at 44.1khz and most NAM players like Tone3k are optimized for 48khz so I'm using more processing power for a worse sample provessing rate, but the IRig devices have a hi z out and will run at 48khz, but I see mixed reviews on them so I'm reaving out for real world experience. How's the latency? Are they huge piles of shit that break after a month? Let me know.
I got a question on NAMFORUM about some of the terminology I'm using for the forum's hierarchical structure. I have my own reasoning behind the choices, but I'm not absolutely convinced they're the best terms.
I'd appreciate it if some of you would take a look at the discussion and offer your thoughts. If there's a better way to organize or describe these categories, I'm all ears. I thought "player" and "capture platform" were widely used terms. Thanks.
Heya! Just wanted to give out a friendly reminder that gain staging when capturing makes ALL the difference! I was trying to capture my pedalboard and was getting an ESR of 0.8 and I was so confused, until I dialed the output gain to come out to just around 12db and lo and behold I got like 0.013, which is crazy!
Since there are some very high bang to the buck obsolete modelers out there, like the HD series from Line 6, and newer NAM captures require so little processing, I can’t help thinking some of them could receive 3rd party software and run NAM. Just use it as a hardware box. Obviously Line 6 won’t support this and would even try to stop it, but in the beginning of R+D or manufacturing, some of these older modelers were just boxes of high quality software available off the shelf (unless it has a custom PROM or FPGA or the like). It was done with the Zoom MS series BTW.
I've been working on this project for a while, and I'm finally ready to share it with you guys.
It's called CrunchyPy, and it's my attempt at recreating the sound and feel of the Mesa/Boogie Mark IIC+, including the mythical ++ mod, as an open-source guitar amp plugin.
I've always been obsessed with the Mark IIC+, especially those tight, aggressive Metallica tones, so I wanted to see how far I could take this idea myself.
The interesting part is how it's built. Instead of feeding the entire amp into one neural network and treating it as a black box, I split the preamp and power amp into separate GRU neural models, with a physically modeled five-band graphic EQ in between. I used LiveSPICE circuit simulations as part of the process, particularly for the EQ.
The plugin is written in C++ using JUCE and RTNeural, and I've been working on the actual DSP and circuit modeling as much as the plugin itself.
And honestly, I'm really happy with how it sounds. It's reached the point where I genuinely enjoy playing through it, which is probably the most satisfying part of this whole project.
It's available as open-source software under GPL-3.0, with support for VST3, AU, and standalone builds across Windows, Linux, and macOS. The amp simulation doesn't include a speaker cabinet IR, so you'll want to use a cab sim or IR loader after it for a finished direct-recording tone.
I'm not claiming it's a perfect replacement for an actual IIC+, and I'd be very interested to hear from people who own or have spent a lot of time with the real thing. I'm especially curious about how the response, EQ, and feel compare from the perspective of someone familiar with these amps.
If anyone is interested in trying it out, checking the implementation, or just discussing the approach, I'd love to hear your thoughts.
This has been a passion project combining my interests in guitar, audio DSP, circuit simulation, and machine learning, and I'm genuinely proud to finally have it out there.
Can the mods put a Vendor tag in here and enforce it? The majority of the posts are just people advertising their newest vibe coded NAM Player. Nothing wrong with advertising, but at least enforce a tag on it so the rest of us can navigate around.
Hey all, Tommy here. I've spent the last ten years recording, mixing and mastering metal, and since July I've been building NAM 9000 on top of Steven's open-source core. Thousands of guitarists have downloaded it so far, the feedback has been really positive, and a lot of what's in it now started as someone's request. Not affiliated with the official project, and none of this exists without his work.
The official plugin is the reference for playing a capture. NAM 9000 is for when you want the capture to be the middle of a rig instead of the whole rig.
WHAT IT PLAYS
Any standard .nam file, A1 or A2. A2 slimmable files get a FULL / LITE switch you can flip while playing. Amp+cab captures turn the built-in cab off by themselves, so you never stack two cabs, and every capture is resampled and loudness-matched at load.
WHAT'S AROUND THE ENGINE (FREE)
- Two NAM engines at once: a captured drive pedal into a captured amp
- Amps captured across their whole gain range, so the GAIN knob cleans up and tightens like the real amp instead of just getting louder
- Pedalboard, graphic and parametric EQ, cab/IR loader for your own IRs, delay, reverb, tuner, presets with A/B
- TONE3000 built in: search, filter by A1/A2, download straight into the right slot
- A capture studio: runs the standard sweep through your amp and trains an A2 .nam on your NVIDIA GPU (Windows), or exports for TONE3000's free online training. The result is a normal .nam that works in any player, the official one included
THE CATCH, UP FRONT
The app is free with no account and no time limit, and that isn't changing. Paid extras fund it: multichannel amp heads (audition any of them free, as often as you like) and Pro, 19 EUR one-time, for two amps in parallel, a stereo dual cab, Render Rig (bakes your whole rig into one .nam) and five house amp heads. Keys unlock offline, no activation server. The download link comes by email: one mail with both installers, one-click unsubscribe.
VST3 + standalone on Windows, AU + VST3 + standalone on macOS (universal, signed and notarized).
a BIG list of new features, incl. NAM calibration and folder imports, remote & sync via iphone/ipad, new and improved algorithms & effects, as well as many UI improvements.
Download is free (incl. multiple free modules, like the NAM player)... and new: free 5-day trial of the complete package.
hope you like it - a lot of you guys feedback went into this update, so thank you!!!
After many, many experiments with Tone3000 captures, I've realized that there are a few important things to consider when trying to get good-sounding, accurate captures of high-gain amps:
Full-rig captures (amp head + cabinet) don't seem to capture as cleanly as amp-only captures. They also take longer to capture and get rejected for tone accuracy more often. NAM users will likely prefer using their own IRs anyway.
Distortion or boost pedals in front of the amp seem to reduce capture accuracy, so don't bother using them. There are already a million boost pedal plugins that users can put in front of the Gateway Player.
Too much gain in general reduces capture accuracy. The capture process can handle a decent amount of gain, but not full-blown death metal chugs (I'm talking strictly in terms of reproduction accuracy). Too much gain introduces artifacts, and the AI just can't seem to distinguish the core tone, resulting in a poor-sounding capture. The ESR will be much higher with too much gain (0.0221), than captures with moderate amounts of gain (0.0002).
Too much bass can also be an issue. It might dominate too much of the waveform, making the capture sound less loud compared to a more midrange-focused capture. Keep a good amount of mids and treble, but don't overdo it.
Takeaway: Don't try to capture a perfected rig with everything dialed in all at once. AI/ML simply doesn't seem to capture extreme metal tones as accurately. It's better to capture the amp head itself with as many different EQ and gain settings as possible. Let users use their own boost pedal plugins and IRs; it'll sound much better in the end.
If you have anything else you'd add, drop it in the comments. Cheers!
Advertising / vendor disclosure: I am Matt from Mattfig and created these captures. The NAM sample below is free; the full pack is commercial.
My CCV NAM pack is live, captured from a Myasnikov CCV preamp running into a Friedman Jose power section, through a Sunn 4×12 with DV77s and Greenbacks.
18 captures cover low, mid and high gain in Normal (Nrm), Sat1 and Sat2 gain-stage settings, each with DI and 4×12 versions. Normal/Sat1/Sat2 describe the gain staging and clipping/compression. DI needs your own cabinet IR; 4×12 includes the cab.
Hello all I was wondering everyone's experience with the conversion of NAM to other means such as MNRS or snap tone. I currently have a mooer ge150 pro and thought it was pretty lackluster conversion on NAM A1. They have since updated to A2 which I have not tried yet. I use a MNRS capture of a 5150 III amp head. Just am curious on what you guys think on conversion, if it sounds any good to your ears or is worth investigating. Thanks to all!!
