Here's FXDB's interview with Eugenio Gregorio of EFX Custom Effects:
How did EFX Custom Effects start?
I was doing small projects while I was studying electric engineering and my friends asked me about one or another guitar effect project so I started to research it.
I started all by myself doing what the guitarists asked me to do, so things developed that way, always trying to attend guitarists needs.
Where do the name and logo come from?
E is the first letter of my name, FX come from "Effects".
There's no real logo, only the name simply written.
What sets EFX Custom Effects apart from other builders?
I do a honest job, I'm polite and thoughtful with my clients, I'm offering a nice pedal for a nice price.
How do you start on a new pedal?
I see what's new on the market, what people are looking for, and try to get what they need.
How do you name your pedals?
All the pedal names refer to something. It can be another pedal name or color. Like the phaser that is orange, referring to the MXR Phase 90, and so on...
Can you tell us something about the production process?
I work at my house but there are other people helping me out soldering the components in the circuit board.
Circuits are hand wired by me or by 3 other guys that are helping me out. Enclosures are silver finished with some hard sticker. The pedal is light and strong.
How important is the look of your pedals?
Very important. So important that I hired some designers to do it.
Is parts selection important?
I try to make the signal as clear as possible, so I choose the best components, not only in sound, also in durability (like the jacks).
Which of your pedals makes you most proud?
I'm proud of the Tube Baby because it's the best "screamer" on the market. It aggregates all the features of the best screamers in one pedal. That's why it's one of the best selling pedals of my company.
Which of your pedals was your toughest build?
All the tube pedals were hard because it is really hard to work with tubes, it took a lot of prototypes to make all the circuit fit inside the pedal with the clearest sound.
Which of your pedals is the most popular?
Funny the best selling item it's not a pedal, it's the Power Supply. Because it's really clean and handy.
Who uses your pedals and for which genres?
I don't make pedals for specific genres, I try to reach everyone.
I made pedals for many top artists here in Brazil, but I don't have much contact with them, only when they come to buy another pedal.
What does the future of EFX Custom Effects look like?
My main goals are to produce faster because demand is increasing each year and to make new effects or solutions like routers, switchers...
Are you working on any new products?
I always have some new projects in my mind. Actually I'm working on a programmable switcher now.
