Do let me know if there's also a mistake in https://github.com/katana-dev/docs/blob/master/tables/amp-types.md then.

Unless there's an error in the GT-001/GT-100 MIDI spec or an actual firmware difference between those products and Katana, your listing looks right.  My ears tell me that Acoustic is a flat-response preamp, but I'll re-check this evening.

Gumtown, thank you so much for this wonderful piece of software.  I don't own the Katana or GT100, but I do own the GT-001 and the GT-1.  I can now look at any patch and get an idea of how the EQ is set and convert this to my GT-001 or GT-1.  You are very smart for figuring this out!

https://www.thegearpage.net/board/index.php?posts/24179826/

I finally found a bit of time to play with the floorboard app. Custom amps are very nice. I don't recall the exact settings I used, but with a Custom based on the Crunch channel, and settings vaguely like the below, I got something that does a pretty good cranked small tweed imitation. I could probably get closer with an actual A/B comparison, but I really just want to evoke the feel and this is close enough for my ear.

Gain: 2-3 o'clock
Amp EQ: lots of mids.
Presence: I think I have it at 0.

Custom: Crunch
Bottom end: -10
Edge: -20, I think.
Pre treble and bass at 0.
Character at +10.

I can't get T-comp to stick (it reverts to 0 after saving), and it could use a bit more sag, but even so, it feels reasonably appropriate. Could always play with Compressor attack values.

I wasn't quite as happy with my squeaky clean Fender attempt, but I'll give it a go against Amplitube's Super Reverb at some point and see if I can get there.

But when adjusting T-Comp, does it actually apply an audible change in Katana tone or feel ( as adjusting T-Comp on the GP-10 does?) 


Others report T-Comp setting DOES make a difference on some Katana Sneaky Amp models

It's hard to say definitively because it's fairly subtle, but it's a solid maybe. It may vary by model too. I felt like the difference was more obvious with the Plexi model than the custom crunch, for instance. It feels more like a compressor than a sag control, though, to the extent that they're different. I hear more of a response time delay with a Tweed Deluxe, and t-comp doesn't seem to do that.

I might pop a looper in front to twiddle the knob with a steady signal, but I don't think I'll be able to do that for a while because it sounds like work.

When adjusting T-Comp on the Custom amp, I'm sure I was hearing a change, but same as nonsense mentioned, it was reverting back to zero after saving.

That's not a bug. T-Comp is disabled in firmware.
https://github.com/katana-dev/docs/blob/master/tables/patch-capabilities.md#sysex-patch-blocks

I'm not 100% convinced that it's disabled.  It isn't being saved and restored, but I can swear I hear it doing something when manually set from FxFloorboard.  Certainly this could be wishful thinking on my part.

I find it really hard to tell the difference in sound. Not sure what I'm looking for even.
For the GT-100 for example:

https://youtu.be/p5WYmNuO0WM?t=3m39s


The firmware however looks absolutely fixed in this.



Write a 0 value into panel T-Comp (0 corresponds with -20 T-Comp):
 >| Katana Command #[60 00 00 53] length(1), data = 00

Note: this is with BTS mode on, and there is no confirmation of a change. Normally this would be reported.

Query the current panel T-Comp value:
 >| Katana Query   #[60 00 00 53] length(1)
|<  Katana Command #[60 00 00 53] length(1), data = 0A

Result is 0x0A = +0 T-Comp value

Write a 127 value into panel T-Comp (beyond maximum value, other parameters normally jump to their max value this way):
 >| Katana Command #[60 00 00 53] length(1), data = 7F

Again, no change reported with BTS mode on.

Query the current panel T-Comp value:
 >| Katana Query   #[60 00 00 53] length(1)
|<  Katana Command #[60 00 00 53] length(1), data = 0A

Result is 0x0A = +0 T-Comp value


I have a looper available, so what sort of effect *should* it have?
Should it just do flat compression?

Changing the "T-Comp" parameter impacts the feel / squish  / compression of the current Amp model

you will only feel the impact  of T-Comp change under the fingers - and not hear the difference of T-Comp change in a recording or Youtube demo.

It make a difference on Boss Gear that supports "T-Comp" ( Boss GP-10, GT-001, GT-100 Version 2)

This thing was getting more mythical by the day.
My post here should clear it up http://www.vguitarforums.com/smf/index.php?topic=21018.0

Using cancellation to find if T-Comb changes my loop, I found:

Conclusion

The T-Comp parameter definitely does nothing.
If you don't believe waveforms, I've exported the original recordings and the canceled mixes, feel free to listen for yourself.

For clarity, all these files in order look like this:

  • TCompTest-Plexi-Full.flac
  • TCompTest-Plexi-PresenceMidCanceled.flac
  • TCompTest-Plexi-TCompCanceled.flac
  • TCompTest-Tweed-Full.flac
  • TCompTest-Tweed-MODCompCanceled.flac
  • TCompTest-Tweed-TCompCanceled.flac

Exactly.  I appreciate Robin's efforts to quantify the situation, but am not completely convinced the approach used would necessary flag what T-Comp does.   A better test might be to drive the preamp into clip with a tone-burst generator and watch the leading part of the output waveform with a scope as the T-Comp control is rotated.

Replied there not to stray off topic too much here.
