Thanks for supporting independent tone.

I had a problem I suspect many of you know: record a few presets, compare them in a mix, and even with matched LUFS they sit at completely different perceived volumes. A dense crunch pushes harder than a clean tone at the same K-weighted number — the ear isn't a meter.

I spent a few months figuring out why. The short answer: LUFS K-weighting treats all frequencies equally, but the ear doesn't. A dense midrange-heavy tone triggers more loudness perception than the number suggests.

So I built something. It measures perceived loudness using a psychoacoustic Bark-band model — same principle as Zwicker's loudness model — and gives you:

- The exact dB correction to apply to each preset's output to match perceived loudness to a reference

- A timbre-only "Character" score (presence, dynamics, stereo width) separated from volume — tells you if a difference is a gain issue or an EQ issue

- Cut-through score — how well the spectrum sits in a dense mix

- 8-band spectral balance with concrete parametric EQ suggestions

- Loudness curve over time (N50 sustain / N5 peaks)

Workflow: record the same passage through each preset, drop the files in, pick a reference, press Analyze. Runs in the browser, no install.

I'm selling it but happy to answer questions about the model or the approach first. Has anyone else run into this problem and how did you solve it?

Am I the only one who feels like some captures actually feel better than the real amp or their corresponding simulation? 🤔
I’ve been playing these AmpGuru captures lately, and the response under the fingers is super nice. Anyone else had the same experience?

I'm a hobbyist, intermediate level. I just love picking up the guitar and playing covers. I kept running into the same thing: I'd hear a tone in a song, sit down with the QC, and lose an hour cycling through amp/cab/EQ combos trying to get close. I'm not great at dialing tones, so most of that was just guessing.

So I made something to cut that out. You give it a song (and the section, like intro/verse/solo), your guitar, and your actual pickups, and it gives you a full signal chain: effects, amp, cab, with the actual parameter values for each block. It's built around your pickups, not some generic database preset.

The part I cared about most: it picks gear from the QC's actual device list instead of making stuff up the way a chatbot would, so the amps, cabs and pedals it gives you are real units that are actually on the QC.

It doesn't export a preset file or sync to the QC, just so that's clear. It gives you the build and you dial it in yourself.

I've been using it for my own covers for over a year. Figured I'd clean it up and put it out there in case anyone else finds it useful. The screenshots are a preset it built for Iron Maiden's Stranger in a Strange Land on my Fender Strat (American Performer). That's the whole chain it came up with.

Curious what you think, especially whether the stuff it picks for your pickups lines up with your experience. Happy to throw up a sound clip if anyone wants to hear how it came out.

If anyone wants to mess with it, it's called RigCraft.

Hey guys, I've been working very hard on these custom protective plates for the QC. My latest design has 5mm of top surface protection, a built-in magnetic screen guard, LED diffusers to increase the LED size from 5mm to 10mm, custom knurled nuts which screw onto the remaining threads of the switches, a kick ring protector for the rotary encoder volume knob and custom colours each side and different pattern finishes. Rob Harris from Jamiroquai is currently using these on his tour units. There are two versions available, one without the screen protector and one with. If they interest you feel free to get in touch on DM. Lead time is about a week as i make each one to order.
