Fractal Talk

Anyone have any settings they can share when using a tube power amp and cab? I just cannot get my current setup LX-II and vertical Mesa 2x12 to sound good to me. It’s so bass heavy and nasal/high end shrill sounding at the same time. Beyond frustrated. Just trying to get a good 5150 sound. I know it’s user error but when I think I have it right, the next day it’s back to square one.

Play around with the Impedance Curves. While not technically “correct”, these can do a lot at shaping what’s coming out of a cabinet you wouldn’t quite expect.

The selectable impedance curves might be my favorite fractal addition. Closely tied with dynacabs

The compressors have been rewritten and are now excellent, added an 1176, killer dynacomp, etc. Lots of new drives and fuzzes, new ways to tweak said fuzzes, new ways to tweak the delay, updated spring reverb, new univibes. Pretty much the biggest effects update in years….

Oh alright, I guess that’s cool. I suppose a small part of my single patch I use will get a little nicer.

Looks like @deadpool_25 arrived with the following settings in the speaker block

LRF: 119
LRQ: 3
LR: 5.8

I did?? I don't even remember that lol. Not really. Maybe a super vague recollection of messing with those a lonnnnng time ago? That must've been when I had an AxeFX II XL+?

Have you tried this?

About Speaker LF Resonance

Most guitar speakers are roughly the same when it comes to the high-frequency reactive behavior. The impedance increases starting around 1 kHz and then increases at 3-4 dB/octave. This is due to the voice coil inductance. A pure inductance would increase at 6 dB/oct. but there are eddy...

But maybe this is old news and how people use to do things pre impedance curve selection

Is that for a 2x12 horizontal or vertical? Would they be the same?

A Mesa 2x12 vert vs horizontal? Technically, no. They wouldn't be exactly the same. Different internal measurements.

@MTB1973

So, with an LX, output mode should be "FRFR"? Speaker drive and thump off.

Ah it was back in 2013 seeing that I probably shouldn't even have tagged you but here we are

That is the recommended starting point. As always, use your ears and adjust to taste.

Can someone help me. I'm trying to do some IEM corrective eq using the PEQ blocks but i can't figure out how to enter the Q values using the keyboard? It only lets me change the Q value via the mouse which is a pain.

Bueller?

 

[Rock Chalk]

Bueller?

Click a knob and then while hovering on that knob hit enter, key in the number, hit enter again.

That worked! Thanks!

I kind of ignored the plex delay block for the longest time. I thought of it as a shimmer machine and I got tired of that sound years ago. Tonight I started playing with it and boy was I ever wrong. There’s some stellar stuff in there that I was overlooking. That’s probably about to make it into my main patch for a while…

So @MTB1973 ....

Got some time to play with the FM9 and LX through my V30 2x12 up LOUD. Got some very nice from the PVH 6160 Lead amp model. Speaker thump and drive off, 2x12 Recto impedance curve. No other deep tweaks beyond that. Works great with Depth on on the LX as well as with it off. Output on the FM9 was about 70-80% and output on LX was around 35-40%

 

[MTB1973]

Thanks - will give it a try. Interesting that you have the master volume at 4.

What did you have yours at?

 

[MTB1973]

What did you have yours at?

Usually 2.5

 

[JiveTurkey]

I basically left most settings at default and iirc; that's where the master was when I added the amp block.

 

[Mongillo19]

Gotcha. Yeah I doubt 2.5 vs 4 will make a huge difference. Even at 4 I doubt there is any power tube saturation or distortion (which imo you don't want in amps like the 5150)
