Frequently Asked Questions
Q.Why does my pedal seems loose and won't stay in the up
position when I play?
A. You can adjust the rocker tension on your pedal by using
an allen wrench. There is a nut on the heel of the pedal.
Simply turn it to the right to tighten it or turn it to the left to
loosen it.
Q. Why does my pedal sound scratchy?
A. It is possible that your pedals potentiometer may have
some dirt or debris in it. Unlike other pedals your pot can be
cleaned by using a lubricant such as Radio Shack #64-4315
or stabilant.  Over a period of years it may become necessary
to replace the pot. I also have replacements available.
Q. My wah doesn't seem to engage easily or it engages too
easily. How do I fix this?
A. Your wah has an adjustable switch that can be lowered or
raised depending on the players preference. Simply loosen
the nut on the top of the switch then give the nut on the inside
of the pedal a turn. Not too much though because a quarter to
a half of a turn will raise or lower it substantially. Raising your
switch too much could cause the switch to become partially
engaged. When this happens you will notice a buzzing noise
when engaging your pedal. Please make sure this is not the
case before contacting me about any problems.
Q.What type of power supply does your wah take?
A. We use Boss style 2.1mm negative center power jacks
9vdc.
Q. There is a nasty hum that my pedal seems to be making
when I use it with a power supply. How do I fix this?
A. When using an external power supply always make sure
that you are using a high quality regulated power supply.
When using cheap unregulated power supplies your pedal
can pickup the EMI (electro-magnetic interference) that these
supplies tend to emit. So always use a high quality power
supply. This is a common problem with the wah circuit itself.
Q. When I turn my pedal on there seems to be a slight drop in
the volume, especially on the clean channel of my amp.
What's wrong?
A. Your pedal has a volume trimmer on the output buffer.
Make sure that you don't have it turned down too much. This
feature allows you to control the output of the pedal.
Q. I use a fuzz foot or face can your pedal be used ahead of
them and still cut through the signal?
A. Yes every Wilson Effects wah comes standard with an
output buffer so there is no need to worry about the placement
of your wah in your effects chain.
Q. Are your pedals true bypass?
A. Yes all of my pedals are true bypass using only the highest
quality switches.
Q. Are my switch and potentiometer covered by the one year
warranty?
A. No the switch and pot are friction based components and
due to wear and tear may go bad over time. However they do
have a warranty for the first thirty days you have your pedal
just in case it could be a factory flawed part. I do sell
replacement switches and pots for your pedal. I don't
advertise them on the site because I'm not a parts dealer so if
you find yourself needing a replacement just email me and I
can get you one at a very reasonable cost.
Q. If I choose to replace my pot or switch myself does this void
my warranty?
A. No. If you find that you need to do one of the above tasks
you do not have to send your pedal back to me to do the
repair. If however you need any assistance I would be happy
to help out through email.
Q. If my pedal needs repaired can I take it to someone else or
try to repair it myself under warranty
A. If you find that you are having problems with your pedal you
can send it back to me and I will be happy to do the warranty
work on your pedal. However if you or anyone else attempt to
mod or repair it you may in fact void your warranty. If you've
bought your pedal from a dealer make sure that you send a
copy of the original receipt because I do not have records of
your transactions with my dealers.
Q. I spilled some liquid on my pedal or I dropped my pedal
and broke it, or I plugged my pedal into the wrong power
supply and it no longer works. Is this covered under warranty?
A. No only the manufacturers parts and labor are covered. I
will however be happy to look at it and get it back to working
condition for a reasonable price.
Q. My pedal is no longer under warranty and something is
wrong with it. Can you fix it?
A. If your pedal is no longer under warranty I can still do the
repairs for a reasonable cost.
Q. How do I send my pedal to you?
A. Email me for the proper instructions.
