    I'd like to share some information, and resources, which are useful to get the most of the wah effect within the Amplifire.

    I told myself that as soon as the forum was running, I'd post what I'd learned over the past twelve months of having my Amplifire.

    I did a lot of searching around last year to find out how to make a great wah with my AF3, using an expression pedal in the loop.

    I found the Sweetwater Dunlop Wah comparison page to be invaluable, for getting frequencies for classic wah sounds. This page shows all (I think) of the current models of Dunlop Wah frequency values - http://www.sweetwater.com/feature/dunlop/wah-pedals/

    There is a Sweetwater video with a comparison of some of the Dunlop Wah pedals as well here:



    Bryan Keyhoe, the Dunlop demonstrator describes the 'Q' values between some of their pedals on the video, in fairly basic terms, but the differences can be heard, and the comparisons are useful.

    Using this information, I created the following wah block which is based on the original Crybaby GCB95 wah:

    This is my go to wah, which I find works with all kinds of amps.

    I've set this to be a Lowpass wah rather than a Bandpass. I've seen some peoples' wah settings built with a bandpass filter, but I find this to be more musical and easier to cut through a band without it losing too much low end when working. This works just like a crybaby with a resonant peak near the cutoff point of the lowpass in operation, giving it's tone and character.

    The Freq Min and Max are set at 350Hz and 2.2 KHz, as per the original Crybaby values.

    There is no Q value stated on the Sweetwater page, so I adjusted this until I came up with one I liked. Lower values will be flatter in response, and higher values will be have a sharper resonant peak, and sound sharper and more nasal.

    The T parameters (Sense, Attack and Release), along with the LFO parameters can be ignored. They won't have any effect in a pedal wah like this.

    The PARK, Threshold and Timer settings allow the wah to switch off automatically when the heel is down (below 28% in this instance), and only after the Timer value has elapsed.

    I've compared this to my Self-modified Crybaby, and it sounds really close. It works great in my band, and really sounds amazing. I'd use this rather than the Crybaby as it doesn't suffer from any microphonics (I put a Fulltone Halo inductor in mine).

    I've got to give a credit to Dipendra Bagchee for his great YouTube video where he tone matched his Jerry Cantrell Wah - this was a big source of inspiration.



    Also, the great Rich Antonelli has posted a great video about patching an expression pedal for a wah into an Amplifire




    I hope this is useful to you.

    Simon.

    Great post! That comparison video is a great way to hear the differences directly between all those wahs. It's pretty cool that pretty much all those sounds can be made in the Amplifire!

    Great read and very informative! I was actually messing around with my AA wah sound the other night and couldn't quite get it where I wanted it - will definitely be giving your tips a try.

    Thank you very much!

    I was trying to get a good wah sound and I ended up setting the taper to 100% and I really like the vocal "wow" sound this made. The manual says this a reverse audio taper - I don't know what that means or if that setting even makes sense but I think it sounds cool.

    For an example, let's set pedal 0% = 200Hz, 100% = 3200Hz (4 octaves).

    A linear taper (taper=50%) is where the pedal % is linearly proportional to frequency. In this case, pedal-50% is the midpoint between 200Hz and 3200Hz.
    0% - 200Hz
    25% - 950Hz
    50% - 1700Hz
    75% - 2450Hz
    100% - 3200Hz

    An audio taper follows a logarithmic curve, which is common to how humans perceive things like loudness and pitch. Pedal-50% will be less than the linear midpoint. Example:
    0% - 200Hz (octave 0)
    25% - 400Hz (oct. 1)
    50% - 800Hz (oct. 2)
    75% - 1600Hz (oct. 3)
    100% - 3200Hz (oct. 4)

    A reverse audio taper is simply the inverse of the above, where pedal-50% is higher than linear midpoint. Example:
    0% - 200Hz
    25% - 1800Hz
    50% - 2600Hz
    75% - 3000Hz
    100% - 3200Hz

    In this application, the higher the Taper setting:
    - the bigger the sweep at the beginning from pedal-0%
    -the smaller the sweep towards the end at pedal approaching 100%

    Has anyone recreated a "talk box" effect or anything approximating that kind of effect?

    I think that would be a great effect. I had a Sonuus Wahoo a couple of years ago, which has programmable dual filters. You can set vowel sounds, and get fairly authentic talk effects using the pedal.

    I reckon the Amplifire could have a talk wah setting, where the vowel sounds could be programmed. That would make Livin' on a prayer much easier to play!

    I still can't get a great wah sound. It always changes the tone of the amp so dramatically. No matter what I do it's always really bassy (which I counter by adjusting the amp bass) and the high end almost sounds like it's distorting. What I'd ideally like is my clean sound, which is awesome, with some wah flavoring that doesn't change the overall tone so drastically. I've tried using the lowpass setting to no avail. Frustrating.

    Could you provide your current settings? Maybe someone could help. Also are you using an amp, frfr monitors, headphones etc?
    Was just looking at your pedalboard setup (nice!). Have you tried the expression pedal without the midi pedal to see if it makes any difference?

    I use my AF at home running into JBL 5" monitors. All my settings sound awesome and transfer over live perfectly. We use 2 different sound companies and I sound the same through either monitors that they provide. Since the addition of the LFO Wah, I've been using that and not even touching the pedal. Either way, it's the same tone no matter which setup I use.

    With the wah off my clean sound is full and clear. When I kick the wah on it just doesn't sound great.

    My settings
    Type - Bandpass
    Pedal - 100%
    Taper - 50%
    Freq Min - .34kHz
    Freq Max - 1.76kHz
    Q - 4.7
    Level - 15.8

    Well, not the speakers or pedal. Only setting I'd think would make a difference would be the level (I run 0) but daughter is using the basement right now so I can't go noodle around to check. Curious.

    I've ran it at zero and it has the same effect.

    Yup. I love played around with the min frequency setting and could dial out the Low end but it still "colors" the sound. I found the way to be kinda blah at first but have warmed up to it the more I use it.

    It's alright. I just wish there was a version of it that didn't color the sound so much.

    What position do you have it in? Where it is in the chain would make a big difference.

    I'm pretty sure you can't change the wah pedal position in the chain. Was looking to see if it could last night. You can move the loop but I doesn't make a difference with regards to the wah sound.
