The DG30 is so different from other amps I have had that I decided to try an unusual pedal with it - the Fulltone Secret Freq.
This is an OD pedal that seems to me to be similar in some ways to an OCD, only with a midrange control that adds a cocked wah sound, in other words, a midrange filter that can be turned off completely, or rolled up in amplitude to be more exaggerated to make, say, a solo stand out more in a mix.
What's cool is that it doesn't attenuate the high and low frequencies like a cocked wah, so it's merely adding additional midrange.
It's also got a very effective treble control that can roll off the treble; the control is simply a "cut" control, which is definitely helpful when the mids are boosted so the thing doesn't tear your ears off. And of course, it has the typical volume and gain knobs. So it's very simple to use.
Set like I have it in the picture, I get a nice amount of gain that sounds good with the DG amp, a light boost in the midrange, and it has a good balance with the natural sound of the amp. I think I like it a little better than the FD3 with this particular amp.
Anyone else tried one? It's a pretty cool pedal. Sounds good with my HXDA, too, but really a natural with the DG30.
