Here's FXDB's interview with Roy of Greenhouse Effects:
How did Greenhouse Effects start?
I got into it back in 2004 when I was already diagnosed with severe stompboxoholic. I had loads of pedals, loved them all, wanted them all. But mostly I wanted to know what makes them sound like they do.
I started looking for more info online. Once I knew enough to start building it myself, it boosted my enthusiasm a lot. Having other musicians buying and using my pedals boosted it even further.
I used to know a colleague that started at about the same time as me, we shared ideas and techniques but we were both after different sounds and so eventually grew apart. I really appreciate some of the contemporary pedal makers. Mostly the ones that push the envelope and do things differently are the ones who inspire me the most.
Where do the name and logo come from?
The name originated from the lyrics of Megadeth's song "Down patrol", but it fits the environment in which the pedals are being made.
First the logo was the letters G and H drawn together to shape the form of a house. Later it was revised and simplified to the present one.
What sets Greenhouse Effects apart from other builders?
I would say that there's a distinctive quality to the GH line of pedals. They all do much more then you'd expect them to.
My benchmark is a pedal that inspires you to play instead of getting in the way.
I remember the moment of finding my own distinctive sweet spot on a certain pedal, one that helped me define "My tone". That is what I want my costumers to have with my pedals. That's why they are packed with an array of tones and sometimes need to be operated in an unorthodox way.
How do you start on a new pedal?
My head is packed with ideas,dreams and fantasies about pedals and tones. If my technical abilities hold me back from achieving my goal I wait until I know enough and test myself to see if the final result is worth releasing.
I ask colleagues, friends, sound technicians, musicians and others to get feedback. I use the prototype myself and give it to others to get their feedback. Then it's time for production. Ordering parts, designing the artwork and assembly.
How do you name your pedals?
The design concept behind the current line of GH pedals is the legendary 27 club. Each pedal has an image that captures the cause of death of each of the respectful musicians related to that club. Names for each pedal are selected accordingly and sometimes reflect both the pedals functionality and its origin.
How important is the look of your pedals?
It is incredibly important but only comes after sound and interface.
Is parts selection important?
I do my best to stay away from discontinued parts. No Mojo here. Only the best parts for the specific type of pedal.
Which of your pedals makes you most proud?
That's hard to answer. I love them all and I'm proud of each. I love the fact that the Goldrive is so loved by guitar players since it's my favorite overdrive. The Nobrainer is my way of giving back to my roots of metal music. The Middleman is a milestone for me since it's very well designed and doing its job exactly as I wanted. The Remedy is just so gnarly and I don't care if not many people dig it. And the Roadkiller is very unique.
Which of your pedals was your toughest build?
The Roadkiller. It took months to design and finish. I wanted it to have it all and to dazzle people with it. It had to be simple to use but to have three different characters.
Which of your pedals is the most popular?
The Nobrainer is the best seller at this point. Might be because of the publicity it had when it came out, or maybe because it's doing its job extremely well.
Who uses your pedals and for which genres?
GH pedals are made for rock mostly but they go hand in hand to where the electric guitar wonders.
There are many famous users: Dweezil Zappa, Jeff Tuttle and many more. They can be found on the GH website.
What does the future of Greenhouse Effects look like?
Currently doing the best I possibly can to bring you the most musical sounding toneful pedals that will make guitar playing more fun and help you create and express yourself with your instrument of choice.
Short term goals: cool modulation pedals. The Stone Fish Chorus/Vibrato is the first one, now in stores.
Are you working on any new products?
Working on new and cool modulation pedals that will be unique and sound great.
