BYPASS MUTE Internal DIP Switch Inside the STRING9 is a small DIP switch
labeled dry/mute. This switch allows you to choose the signal output from the
EFFECT jack when the STRING9 is in bypass mode.
While the STRING9 is in Bypass, and the DIP switch is set to dry (factory
default), the EFFECT jack outputs the signal present at the INPUT. This is the
standard guitar pedal routing for bypass. Set the DIP switch to mute, and

Controls and Connections

the EFFECT jack output is muted in bypass. This is handy when sending the
STRING9’s string effects to a different amplifier or mixer channel and you
don’t want to hear your guitar out of that amp while in bypass.
To change the dry/mute DIP switch setting, do the following:
Remove the bottom cover of the STRING9.
Locate the small board with the footswitch and ribbon cable. Here you’ll
find the DIP switch labeled dry and mute.
Change the dry/mute DIP switch setting with a small flathead screwdriver.
Note: this switch is very delicate. Do not force it when changing settings.
If the switch handle doesn’t move easily, try moving it the other way first
and then back to the position you want.

I don’t care how good a pedal sounds, if the dry knob don’t work, and the manufacturer ignores my support request, then I have no use for it. I am not happy with the pedal or EHX support.

Hello EHX, once again….

How do I get the dry knob on the syth9, and the C9 as well, to do anything?, while using the correct adapter that came with these pedals, with output at the effect plug, and wearing headphones, I turned down the effects knob all the way and the dry knob does nothing to the signal, I still hear dry guitar even with the dry knob all the way down, and when the effect knob is brought back up, even all the way, I can still hear the dry signal, again even when the dry knob is turned all the way down, the only way I am able to control the amount of dry signal I am hearing is by turning the effects knob up trying to mask the dry guitar, but even with the effect knob all the way up I’m still hearing some dry guitar coming through.

Another customer of EHX asked this same question and was told to change a DIP switch setting inside the pedal, to me that’s an odd suggestion to make a pedal work as you would expect when you buy it, and from what I am reading online that DIP switch setting has nothing to do with the issue being reported.

I actually ordered the B9 and Bass 9 yesterday morning from Sweetwater, because I was so happy when I initially played with the C9 and synth9, but after playing around with the pedals further and seeing no effect with the dry knob, and seeing other users online, and here at the EHX site, reporting the same issue I had to cancel the order, and will send these pedals back to Sweetwater as well, along with my reviews, If I can’t get some guidance on how to get these dry knobs to act as I expect.

Hi Gerry, I did reach out for support at https://www.ehx.com/support/#Customer-Support, I then got a confirmation back from info@ehx.com Monday morning, it’s Friday afternoon now, we have a gig tomorrow night, the pedals sound great but i just cant get past the fact that i cant make the dry knob do anything on either pedal, it is frustrating call me hard-headed but i wont even put them in my FX loop until i understand what is happening here, is it me?, is it the pedals?, is it a bad production run?, is it the alignment of the planets mocking me? lol

i’m glad it worked out for you, hoping for the same here
