Okay, so a while ago i shared some effect settings that were suppossed to imitate the inner workings of some well known pedals. Given that latelly I have seen several posts related to the use of pedals, I tought that it may be a good idea to continue the series. I take requests if you have any favourite pedal and you are struggling to dial the correct setting on fuse/mustangs

As usual I do my comparisson using Amplitube's included effects, that asre supossed to be certified by the manufacturers or something on those lines.

Today is the turn of probably the most famous phaser pedal the MXR Phase 90.

Here'S an example of the real thing:
http://www.youtube.com/watch?v=qupAS811B00

Base settings used to emulate the pedal:
Level: 5.5 (the pedal seems to do 50% mix wet/dry)
Depth: 5
Feedback: 1.5
Shape: Sine

Settings used to emulate pedal controls:
Speed knob on the pedal:
-minimum = Rate 0.15 Hz
-maximum = Rate 10 Hz

Other adjustments:
-overall the MXR is probably a bit less trebly than the mustang equivalent, so you might want to roll back your guitar tone slightly, but just a pinch
-the original MXR 90 varies depth together with speed (but inverselly) when turning the speed knob. The depth indicated above was for a 2Hz rate, so when decreasing the rate, increase slightly the depth and viceversa.

Wow… that’s fantastic Jedi… I will be trying this out this weekend.

How about a Blues Driver setting or Colorsound Powerboost for the OD side of things. Maybe the old Silicone Fuzz Face? Electric Mistress?

Thanks for your efforts and contributions. Huge

Hi Jedi,
about the phase 90 : I knew that this pedal having a single control (speed) varies the depth optimally (internal default settings) based on what speed you are setting with the knob.
For example usually as we know, work well pairs as low-speed + medium-high depth or on the contrary a very high speed and a low depth ..
maybe we need to find other settings in order to have the right sounds to 4 or 5 different speed settings .. as in the demo of the real thing.


by the way .. also look at the demo of the MXR Phase 100 http://www.youtube.com/watch?v=jv_h5daIk-Q.. the short cover (first minute of the demo) is very nice in reggae style of "Rudie can't fail" The Clash.

the phase 100 actually also has an intensity knob with four selectable amplitudes.. it can do sounds of phase 90 and other sounds. But probably with phaser in the Mustang we should be able to emulate those variations in amplitude ... with the command depth but also Wave (and perhaps even feedback) i think..

do you think is possible to do that?
Dimitri

EDIT: in the demo the guy talks about the Intensity knob that has the function to set different variations in the range of sweep frequency of the phaser. And in some setting is added an amount of feedback/regeneration as we have in Mustang phaser..
So the only parameter we miss should be that in Roland/Boss Phasers called "Manual" :this resembles in part to "intensity" of phase100 because with it you can vary the central frequency of the effect , but I do not know if it acts the same way.

Thanks for the info, I did not know that.
Actually looking at the circuit the MXR Phase 90 'speed' knob alters speed and depth. In fact from what I can see, a very common 'mod' for the pedal is to add a potentiometer to control the depth :)
The settings I shared are for a test setup at 2 Hz that I did, I will add a comment indicating to reduce depth when increasing speed.

very good job, of course!

phase shifter (phaser) is my most beloved effect when I want to make the sound mushy :-)
I think the MXR phasers are absolute references ... some sounds are magic.
in another demo of phase100 it is explained that the Intensity knob acts on pairs of parameters and gives 4 kind of combinations of: frequency sweep amplitude + depth..
here is what meant those drawings of double circles under the "intensity" knob : one circle the frequency sweep amplitude and the other the amplitude of depht.

Sorry guy... this one has gone straight in to the fx guide! ;)

Quick question J2B.

The Ballistics in fuse are in Percentage. Is this how they are in the LCD panel on the MIII?

5.5% on the level knob works out to be about 8 O'Clock on the level knob and Feedback is nearly all the way down on the Fuse GUI. I’m just playing around with Fuse at work and just want to make sure I’m on the same page with your settings so I can load them in when I get home

Thanks again.

Hi Captainc,
as i said some time ago , some parameters have different scale type on Mustang LCD and on the knobs in Fuse..
a typical example : the parameters on a stompbox.. let's say Overdrive: in the display of the amp the scale of parameters is from 1 to 10 as typical Fender amp knobs.
But in Fuse display the scale is from 0.0% to 100.0% .. it is a scale rather different.. and that is the same difference for several other effects/parameters..
you have to mentally calculate what corresponds to a given value on the display Fuse, which you are used to set on the amplifier ..
easy for maximum, minimum, and half .. but for all the rest of values?
if one is not careful we might as well make mistakes believing using the same scale.

and I had reported this thing to Fender because it would be more correct to have the same scale in both displays (from 1 to 10 also in Fuse) so as not to get confused about what you are setting.
And at this point would be useful to have on Fuse also all common parameters (not just advanced parameters) of the amp model showed in the display, to be able to do a precise setting also for owners of amp without display or to get immediate feedback on the set values ​​in a preset downloaded from the community.
