Frequently Asked Questions
What makes Juma pedals different from others on the market?

Our pedals are built to the highest manufacturing and audiophile standards possible using the best of today’s available technologies.  The Supreme Drive is the only pedal ever manufactured in which every single component (and component value) in the signal path was chosen based on extensive, double-blind listening tests by several experienced guitar players.

That's a beautiful enclosure, can you tell me something about it?

Our premium enclosures are 5-axis CNC machined out of aerospace-grade solid aluminum billet.  They are extremely rugged and thick-walled to provide superior strength and electromagnetic shielding.  After a year of design work and dozens of revisions, we ended up with a beautiful enclosure that is a testament to the quality inside.


With such high quality components, aren’t your pedals expensive to build? (Updated)

This comes up often enough that we decided to post some specific info. They are incredibly expensive to build and we’re so proud of it that we’re happy to share this.  At their advertised prices, to purchase a Burson Supreme Sound op amp ($85 USD), three Jupiter copper-foil/beeswax capacitors ($189 USD), three Vishay Z-Foil resistors ($59.85 USD) and three Kilo International aluminum knobs ($33 USD) works out to $366.85 USD plus taxes and shipping from multiple sources.  Add to it the cost of what we pay for our custom, 5-axis CNC-machined enclosures, as well as the rest of the electronic components and our pedal is actually more affordable than the sum of the parts.  In our eyes, this is good, fair business with no artificially-inflated value, which is very rare in any business.

No other pedal company that we know of comes even close to providing customers with more in return for every dollar spent than we do.

I’ve never heard of these electronic components! Why don’t you just use the vintage stuff?

Our double-blind listening tests surprised us time and time again, during which we learned that we consistently and unanimously preferred the sounds of today’s components.  Initially, when we first introduced the Supreme Drive, players questioned the value of using the components that we do.  Since then, we have received many  reports from guitar players that it has become their absolute favorite overdrive/clean boost of all time, even after the initial honeymoon period of owning a new piece of gear has long passed.  Together with it’s simple design, the quality of materials and workmanship is what makes our pedal so special.

I've heard capacitor quality doesn't really make a difference at guitar frequencies. Does it?

Capacitor quality absolutely makes a difference at guitar frequencies.  For example, in one double-blind listening test we compared Wima FKP1, MultiCap RTX and Jupiter copper-foil/beeswax capacitors. The difference in our circuit was so apparent that anyone could spot the difference afterwards in mp3 recordings of those listening tests.

I noticed that your Essence series of pedals uses custom-made capacitors. Can you tell me more about them?

During our double-blind listening tests, our hands-down favorite signal capacitors consistently ended up being the Jupiter copper-foil and beeswax capacitors.  These are one of the best in the world for audio and are expensive to build, so we worked together with Jupiter Condenser to develop a proprietary copper-foil/polypropylene model that uses the same CDE-101 oxygen-free copper foil as their flagship series.  They are hand-made in the USA to Jupiter’s extremely high standards of manufacture and we love how they sound!

I noticed that some of your solder joints aren't shiny. Should I be worried?

Not at all.  Our solder joints will always look dull because that’s the nature of the silver-bearing lead-free solder that we use.  Only solders that contain lead create shiny solder joints.

Will my guitar get lost in the mix with the Supreme Drive, or will it be heard loud and clearly?

We posted a short, 27-second iPhone video clip to our media page because it demonstrates how well the guitar is heard in the mix.  We love that video for that reason.  Check it out, that Tele effortlessly stands out and it sounds incredible!

Ok, I’m sold. How do I order?
Our products can be purchased directly from us through our website.  Please use our shop page and checkout using the PayPal checkout on our website.  If you do not have a PayPal account, you can make a simple credit card payment by using our PayPal checkout.
Is your website secure?
Yes.  In your browser, you will see a small padlock in the top-left corner of your screen on every page of our website.  This symbol represents a secure connection so that your ordering process with us is safe.  Any information you provide us is encrypted on its way from your computer network to ours.
Do you have a return policy and warranty?
Yes.  Our 72-hour return policy is explained on our product pages so that you can read it just before adding a product to your shopping cart.  Our pedals come with a 2-year limited warranty, which can be read in one of our owner’s manuals.
Your website mentions possible waiting periods during busier times. Why are there waiting periods and how long will I have to wait in order to receive my pedal?

We are a small and young business, and our products are expensive and time-consuming for us to build.  When you go to our Shop page and click on one of our pedals to see its product page, you will find our current lead times.

I read somewhere on your website that your products are 100% RoHS compliant. What does that mean?

RoHS stands for, “Restriction of Hazardous Substances,” which restricts the use of several hazardous materials used in electrical and electronic products.  It is the law and every component that we use in our pedals is compliant.  Our pedals are manufactured completely lead-free.

Are you working on any new pedal designs?

We’re always testing new ideas.  We have had several requests to build a TS-inspired model or a FF-inspired fuzz at our level of quality.  We plan on doing both, one at a time in the near future.

What's the correct way to pronounce, "Juma"?
The correct pronunciation of of Juma is Joo-mah.
