What’s the turnaround time for mods and/or new pedals?

The typical wait for new builds and modifications 3-4 weeks, sometimes more, often less. Custom built pedals can often take 2 months or more to complete. There are times when the wait can be as long as 6-8 weeks depending the backlog of work. I’m very thankful for the business and will do what I can to get to yours as soon as I can.

What do I need to do next to get my pedal modified/built?

If/when you’re ready to start send a new email via the contact page with the following details:

  • The mailing address where you’d like your pedals returned. (no P.O. boxes please.)
  • List the mods/pedals you’d like completed.
  • Include your color preference when ordering a new pedal with custom color options. (See available color list below)
  • If ordering a Master Tap Pro with multiple outputs please list the pedals you’re planning to use with it. 

I’ll pass along the shipping information to send your pedal here. Feel free to ship at anytime in the process. Let me know when it’s on the way and I’ll make sure someone’s here to receive it.

In all honesty, if you have a V1 it would be worth it for you to sell the V1, buy a used or new V2 and then have it modified. You will end up roughly the same financially, get the V2 back as much as 2 weeks sooner, and retain all of the stock functions.


Do you offer discounts when combining orders or modifications?

When special discounts are available they will be listed on the pages for each pedal or modification. 

Do I have to pre-pay for my mods or standard pedals?

Early payment for your order is welcome, however, you are not required to fulfill the invoice for your non-custom build/mods until your pedal(s) are ready to ship.

Do I have to pre-pay for my custom pedals and modifications?

Pre-payment of at least 50% is required for all custom pedals and one-off modifications unless I tell you otherwise. If you choose to cancel your order half of the prepayment is non-refundable.

Do you offer artist discounts/endorsement deals/donations/etc.?

 I very rarely provide pedals or work in exchange for “spreading the word” (especially when prompted via email). However, over the course of an agreeable relationship with artists and professional musicians I sometimes choose to invite JHV3 users into a more formal relationship that includes discounts for promotion.

 Do you ship internationally?

 Yes, I will be glad to ship internationally if you can provide the following:

  • Identify your mailing city, providence/state and country within your first communication.
  • Make payment through Paypal only
  • Be willing to take responsibility for all duty and fees to your country related to receiving either new product or your modified equipment. I will not list the contents of international packages as a “gift” under any circumstance; please don’t ask.

“Unfortunately, I can’t have my unit gone that long. I’d really like to send it out, and get _______ done, but I can’t be without it for 3-4 weeks. I’m a working musician, and the _______ is an integral part of my rig. I needed this thing fixed/modded/built, like, yesterday. Can anything be done to expedite this?”

 I understand your dependency on the gear in question, and I will work with you to rush a repair under these specific conditions:

  • 100% of the modification/repair/build/product/return shipping cost is required up front including the additional cost of any expedited return shipping necessary to meet your deadline.
  • By whatever means you find necessary, the pedal must be in my shop for at least 48 hours (for instance 5PM day one till the last mail drop at 5PM day three) to complete the work and deal with any unforeseen issues. 
  • If for any reason you allow less than 36 hrs to complete the work an additional Expedite Fee of $75 will have to be paid via Paypal invoice within 4 hours. If this is not fulfilled in the requested time frame your pedal will either be returned immediately or denied acceptance at delivery and your initial payment refunded minus any return shipping charges we incur in the process.
  • If you foresee your circumstances limit our time with your gear to 24 hours or less, there’s a non-refundable $125 rush charge in addition to the total cost of work/product and return shipping.

I appreciate your understanding and valuing of time and resources as well as your respect of the time and patience of other clients who will be affected by taking on your project.

“Why aren’t my LEDs flashing at the same time?”
“Why aren’t my pedals showing the same BPM?”

As long as your repeats sound the same, ignore the LEDs and displays. When syncing pedals from different companies (sometimes the same) there will be some departure eventually, especially in the visual feedback of the LED.

Most time based effects have separate systems that handle user interface (buttons, switches, knobs, LEDs and indicators) and another for DSP (ad/da conversion, sound manipulation etc.) 120bpm on an M9 from Line6 may be 118.5bpm on a Nova Delay which may be 121bpm on another, while Ableton is saying the tempo is 119. The point being, bpm readings are about as accurate as the clocks in automobiles, and each company has their own way of determining BPM that’s compatible with the rest of their system.

Because the user interface (UI) handles more input (buttons, foot switchesknobs, Expression pedals, translating MIDI information) with varying requirements it’s constantly managing output (indicators displays) while reading input (checking to see if things have changed, and sending that information to the DSP). This communication itself is a priority in well coded systems and may pause the function of flashing the tempo LED. When the UI controller is done sending an update to the DSP, then it comes back to the task of showing tempo. Even though the difference is measured micro seconds, combine these margins together with other pedals and you will noticed a difference most profoundly in the visual feedback, more subtly in the actual function of the pedal.

This is also true with BPM displays on pedals when both syncing with a single switch or via MIDI tempo messages. There is much unnecessary grief caused by BPM displays that will not align, because of similar differences explained above. Add into this equation the differences in how MIDI messages are managed by each system. Regardless of whether or not the incoming MIDI is translated with the same controller that juggles other responsibilities in the device or with dedicated hardware, I would argue that very rarely will two devices from different pedal companies display exactly the same tempo. However, when leveraging the best sync methods in a live situation you should not hear the difference unless the two systems are very incompatible.

Watch this video demonstrating the JHV3 MTPro Pulse/Ping mod between two Nova Delays and an Eventide Timefactor.  While one Nova is the “Master Tempo” sending a steady even signal, notice two things: 

  1. The slave ND-1’s tempo interprets the signal and displays the BPM exactly as the source, while the Timefactor interprets the timing differently and displays it’s result. 
  2. When the MTPro is active all LEDs flash at the same time, when deactivated they eventually digress. 

(Even further, but not shown in the video, if the controls other than time are adjusted on the slave Nova Delay the tempo led will begin to lose sync with the master Nova.)

To experience this your self try the following experiment: as shown in the video typically a time based effect that has a BPM display also has a tempo LED flashing with each “beat”. Try manually dialing in the same BPM on each pedal as close as possible (some will average to the 10th of a beat making it difficult to get whole numbers. Remember, good or bad, the whole number pedals average this for you). Now observe the tempo LEDs, are they flashing in sync? If so, how long does it take for you to notice them depart? Do they seem to sync back after a short time?  Can you hear a difference? If you’re using more than two pedals in this experiment which ones seem to align the most? Can you adjust one pedal +/- to get it to sync LEDs? Can you hear a difference now?

All this being said, think from the perspective of the pedal designer/programmer: what would be their overriding priority in the design process? How many of their users actually implement MIDI? How many will further be syncing other pedals? Will having some MIDI functions give the perception of greater value/features to the consumer? Further, the designer more than not thinks exclusively: “Why should we make it easier to manually sync with other manual pedals from other companies? Can they not just tap the same tempo into the other pedal?” or “That’s what MIDI is for.” or “Why would they need another delay after they buy ours?!”

In my experience, most companies with multiple time based effects make little effort to explicitly help consumers sync their own pedal lines! One non-MIDI exception to this is the latest gear from Cusack pedals. Not only do each have a remote tempo input, but also the Pedalboard Tamer includes a feature to sync multiple pedals, even from preset tempos when recalling scenes of active pedals (John Cusack is brilliant). Eventide goes out of it’s way to explain make MIDI sync between their Factor series pedals.


Do the math in your own head: more users will be inputting tempo manually via an onboard tempo switch than will be leveraging MIDI. So if inputting different tempo other than the “time” knob on the device is a priority then the tap tempo must be as accurate as possible. This is the argument I would make, that the best way to get multiple time based effects to sync is to leverage their most accurate means of determining tempo on the fly at the same time. (This is the primary design goal of the MTPro in it’s various applications.)

This being said, all hope is not lost! It’s not as bad as it may look. Try this experiment that should either restore your confidence in your current rig (especially when using a MTPro) or confirm your need for a more accurate solution:

Start by setting all of your delay pedals to quarter notes, digital delay for pristine repeats, roughly the same feedback/mix, close your eyes, tap tempo into your master switch then hit short percussive rakes on muted strings listening to the repeats. Tap just enough to sync then stop. You should hear just one repeat, as if you have just one delay. Continue to strike the strings enough to hear the delay repeats clearly, after a few seconds you may hear the repeat get slightly “bigger” or even grow a more “analog” sounding tone for a second or two. This is the margin between pedals at it’s greatest. Continue to listen, in about the same time they will realign sounding more pristine.

You may encounter this, you may not. If each DSP is handling the tempo on its own terms you many not perceive the difference. Only when you open your eyes will you realize that the LEDs and BPM displays seem to have their own sense of what time it is.

Bottom Line: Trust your ears. If it sounds in sync, it probably is.
