Hi,

is there anywhere a detailed description of the Mustang Effects. I don't understand the function of certain knobs on some effects. Such as the AVG DLY and LR PHASE on the Chorus or DUTY CYC on the VintageTrem.

I guess there must be a parameter overview somewhere, but I can't find it.

Grab a PDF Manual for your Amp type here.

I haven't actually found this sort of detail in any of the Mustang manuals. I don't think they're supposed to be mysterious, they represent standard controls for the respective effects. Maybe some of these will help.

Chorus:
Thousands of monkeys are sat on stools in a large hall. Each has a guitar like yours (getting repetitive yet?). They are all sat at different distances from you, and hence hear what you’re playing at different times. As soon as you start to play, they all copy what you’re playing. In an analog chorus, laid-back hippy monkeys (see analog delay) are used; in a digital delay straight-laced actuary monkeys are used. Because they are all playing just slightly out of sync with you, it gives a much richer, fuller sound. In most types of chorus, the monkeys are actually sitting on an old-style fairground carousel, and therefore each gets nearer and further away from you, hence playing with a different delay as the carousel turns and giving a warbled sound.


Yada yada tiny tiny monkeys yada yada. Nice knob controls how fast the carousel spins. Ta da!


A chorus is similar to a flanger. It's a short delay that has it's output modulated with an LFO and fed back into the signal. It's usually used to "thicken" a signal. With any short delay, some phasing usually occurs. The Average Delay control dictates how long the delay is set for and the LR Phase adjusts the amount of phasing that is audible to you.


Wikipedia wrote:
Low-frequency oscillation (LFO) is an electronic signal, which is usually below 20 Hz and creates a rhythmic pulse or sweep. This pulse or sweep is often used to modulate synthesizers, delay lines and other audio equipment in order to create effects used in the production of electronic music. Audio effects such as vibrato, tremolo, and flanging are examples. The abbreviation is also very often used to refer to low-frequency oscillators themselves.


The "Var" Switch
For greatest flexibility, it's desireable for a tremolo to offer control of the duty cycle of the controlling signal, i. e., what percent of the time is it "on" and what percent "off"? Getting an uneven duty cycle from a 555 oscillator is easy; it's getting equal on and off times that takes a little doing.

or check the BOSS Effects website. They have more detailed product manuals, on ALL effects....PPL here said it works ok with the Mustang Amps.
