revision 89 is not working... the gui crashes... can't edit any IR files or run guitarix.. No message in terminal.
Also brummer, have you tried a waveshaper for the preamp section? I mean being able to get a crunch out of the amp without using overdrive or distortion. I mean like the vsts. They simulate a tube amp like a marshall, soldano, mesa, etc. Then they have boost or distorion or overdrive to add the edge.
The reason I said waveshaper because it's the only thing that linux has that has a decent distortion (if you can get past or control the noise)
I've been toying around with some of the free vst plugins for guitar and they sound amazing.

@funkmuscle, maybe you can make an list with good IR files to use with guitarix/jconv?

Do you use those VST on Linux btw?

funkmuscle · Post by **funkmuscle** » Thu Apr 30, 2009 4:09 pm

yeah, the work on linux but I don't use them... I just use them to compare with what we have fofr guitar on linux.
yeah... I will give some links to some great sound guitar IR files...

funkmuscle · Post by **funkmuscle** » Thu Apr 30, 2009 4:27 pm

I think you need to register with these sites but they have so good IR files:

http://www.ultimatemetal.com/forum/equi ... pulse.html

This link is where I get the most from and yes, you do have to register... I think the more linux guitarist there, the more thse guys may wanna port their vsts to linux.

All the devs who make the awesome sound free vsts are there:

revision 89 is not working... the gui crashes... can't edit any IR files or run guitarix.. No message in terminal.

witch revision was the last you check out, that work fine for you ?

EDIT: revison 90 include a wavesharper as preamp again.

funkmuscle · Post by **funkmuscle** » Fri May 01, 2009 1:23 pm

yeah, that sounds better... I read on some of the vst sites that these guys start with a waveshaper or even the schematics of the actual amp to create the amp sims.
Have you tried any of them from the link I posted? guitarix got a nice bluesy sound on a single coil pickup... I use it when I'm in a Hendrix mood.
If you can get guitarix to the sound level of some of the free ampsim vsts on that site, we'll have a winner because guitarix offers more than just an amp.

If you can get guitarix to the sound level of some of the free ampsim vsts on that site, we'll have a winner . . .

I will try . . .

I have set a antialiase filter befor the input, that make the sound more smoth, try it (rev 91) and let me know what you think about that.

funkmuscle · Post by **funkmuscle** » Sat May 02, 2009 11:15 am

I will try 91. I don't get the official releases, I get the svn so I can test it for you...

funkmuscle · Post by **funkmuscle** » Sat May 02, 2009 11:48 am

I like the anti aliase. It adds like a clean smooth boost without distortion. Nice for bluesy tones. Still can't get a decent crunch out of the preamp. When I add overdrive, the sound breaks instead of a smooth distorted tone. The distortion doesn't seem to work at all.
It's getting there man... I wish I could do more that just test but what you're doing is too advanced for me by 100%.

brummer · Post by **brummer** » Sat May 02, 2009 1:08 pm

When I add overdrive, the sound breaks instead of a smooth distorted tone.

try it together with the compressor.

The distortion doesn't seem to work at all

I have re-range the distortion volume, have a look at the advanced settings, and maybe adjust the gain new.
Also here you get well distortion sounds, when you use the compressor to limit the output.

EDIT2::
I have add a chebyshev waveshaper to the overdrive sektion now, it is used when distortion is off.
I guess it bring's a litlle crunsh in the output.

funkmuscle · Post by **funkmuscle** » Sat May 02, 2009 6:58 pm

yes, I just tried it. It gives now a little better distortion and a bite to the bluesy tone. Can't get a good metal tone yet...

brummer · Post by **brummer** » Sun May 03, 2009 7:25 am

rev 94
add fuzzy and valve (tube) to preamp and distortion
be carefull with the gain settings,

dont forget about the compressor
