Will you have a __________ pedal in the future?

We understand that you may be delaying a purchase, hoping to get the "latest and greatest." However, we cannot discuss what products we may/may not be working on or planning to introduce in the future. The reason for this is usually one of the following:

  • We have no plans for this now, but this could change.
  • We have plans to do this, but we don't know when. Also, these plans could change.
  • We are working on this, but we are not ready to publicly announce it yet (due to several factors).

Please understand that we cannot reveal anything to you in a "private" e-mail that we wouldn't want made public, because there are those people who will copy-and-paste this information into a public forum. Not saying you would; but we don't really know you, do we?

Can you build a 2-in-1 (or 3-in-1) pedal?

We could, but we won't. Here's why:

    1. Building 2 pedals into 1 enclosure is not much less expensive.
    2. Building 2 pedals into 1 enclosure is not much smaller.
    3. Building 2 pedals into 1 enclosure only cannibalizes sales from our other pedals, therefore making all our pedals more expensive to build (re: economies of scale, then see point #1).
    4. Designing 2-in-1 pedals takes time away from developing new products. Here, "new" means different. Yes, there is more to it than slapping 2 PC boards into a bigger enclosurea lot more.


What's the difference between your different pedals?

Please see this comparison for a summary of the similarities and differences.

What if my rig hums when using a Stereo Pedal with 2 amps?

Hum or buzz is usually caused by a ground loop and is more likely if the two amps are not the same type. The potential for ground-loop hum can be reduced by plugging your amps into the same power outlet or power strip.

There is a simple test to check if your amps are susceptible to ground-loop hum: plug a guitar cable between the inputs of the two amps. Yes, this sounds strange, but it will not harm the amps. This is simply connecting the grounds of the two amps at their inputs. Whether or not this results in hum or buzz will be the same if you run a Stereo Pedal to the two amps.

As you can see from this test, ground-loop hum is entirely dependent on the amps. If your rig does hum when using a stereo pedal, we recommend using an Ebtech Hum X on the AC plug of one amp.

What is the best way to order my effects?

We recommend chorus ► delay ► reverb at the end of the signal chain. One of the better explanations is provided here.

Shimmer can be placed in various locations depending on the desired effect. We prefer to put shimmer before chorus (if you have one), because chorus before shimmer can increase dissonance in the shimmer effect. If you will be using the hold-for-shimmer feature in our pedals (for occasional reverb-only), then put the shimmer at the end of the signal chain. 

Infinity Hold can be placed anywhere after an overdrive, depending on what you want to hold in the loop.

Will this pedal work in front of my amp / in the effects loop?

Effects such as reverb, chorus and delay work best after distortion or overdrive. If you run your amp clean, then these effects will work before the input to your amp. If you use the overdrive in your amp, then these effects should be put in the effects loop.

There is a lot of variation between effect loop levels, so we cannot absolutely guarantee that our pedals will work in your effects loop. Generally speaking, if similar 9V-powered pedals work in your effects loop, then our pedals will too.

If you have problems with instrument-level effects in your loop, you may want to try an Ebtech LLS2 Line Level Shifter.

Is buffered bypass or true bypass better for me?

Short answer: see this flowchart. Long answer...

First, the type of bypass only applies to when the pedal is actually bypassed. When the pedal is active, the signal is buffered--regardless of the type of bypass. So, if your pedal will be active all the time (as a reverb pedal might be), then save yourself some money and opt for the buffered-bypass version of the pedal.

That said, we generally recommend that the first and last pedals in any pedal chain be a buffer, a buffered-bypass pedal, or an "always on" pedal. This ensures two things:

  1. a constant input impedance presented to the send (effect send or instrument), ensuring consistent tone when bypassing effects, and
  2. an uninterrupted output driver to the return (effect return or amplifier input), minimizing any true-bypass switch pops due to slight differences between local ground references.

The pedals between these two may be true bypass, if so desired. The more pedals you have, the more you may want them to be true bypass to minimize any accumulated noise. However, if you only have a few pedals, then it's less critical that they be true bypass.

If you are still uncertain, then get the true bypass option. On our pedals, you can always configure a true bypass pedal as buffered bypass if you were to have any issues with true bypass.

Can I have trails with true bypass?

True bypass is equivalent to patching a cable around the effect; both the input and output of the effect are disconnected from the signal. This makes it impossible to have trails, which requires that the output of the effect remain connected.

However, our true-bypass effects have an option for buffered trails (see the User Guide). Some effects also have the option for "two-stage" bypass, which is a hybrid between true bypass and buffered bypass. To our knowledge, this is the closest thing to having both trails and true bypass at the same time.

Is there an advantage to a 12V adapter rather than 9V?

The only advantage is an additional 2.5 dB of dry-signal headroom. This is imperceptible under most circumstances; however, it may be appropriate for a line-level effects loop.

Why don't your pedals take a battery?

Versions 1 and 2 of the mono Wet Reverb supported a battery. We used an internal switching power supply to increase the battery life to 12 hours (which would otherwise be about 6 hours), and this made the pedal more expensive and prone to failure; even though only about 10% of customers used batteries.

Will your pedals work well with my instrument?

Our pedals have been designed to work well with many instruments, and in particular, stringed instruments. This includes guitar, bass guitar, pedal steel guitar, violin, keyboards, organ, etc.

Why does reverb sound louder with overdrive than with a clean signal?

As far as we know, all reverb pedals do this to some extent. An overdriven signal has more energy than a clean signal (at a given level), which results in the reverb tail sounding louder.

Why do I hear a short delay before the reverb?

In reverb parlance, this is called pre-delay. This is normal and an integral part of the Wet Reverb 1.x algorithm. Pre-delay separates the reverb tail from the dry signal, resulting in greater transparency. Reverbs without sufficient pre-delay tend to "wash over" or "cover" the dry signal.

If you are accustomed to a reverb without pre-delay (such as a spring reverb), this may sound unusual at first. However, an overwhelming majority of users come to appreciate the pre-delay after a short adjustment period.

If you prefer less pre-delay, then please try one of our newer reverb algorithms available via the Expanse Series or the Immerse Reverberator.

How has the Wet Mono Reverb changed between versions?

There have been 5 versions of the mono Wet Mono Reverb:

  • v1 (model year 2009, brushed aluminum with blue & silver overlay)
  • v2a (model year 2010, black with black & silver overlay)
  • v2b (model year 2011, black with black & silver overlay)
  • v3 (model year 2012-13, black with dark blue & white overlay)
  • v4/v4tb (model year mid-2014+)

With respect to the original version 1, version 2a:

  • increased the Mix knob range to go 100% wet at full clockwise
  • increased the Depth knob range to go to "near infinite" at full clockwise
  • tweaked the lower Depth knob range to sound less "slappy" and more like a small room
  • increased the size of the battery compartment to accommodate a larger battery (i.e., rechargeables)

With respect to the version 2a, version 2b:

  • replaced the true bypass with a switchable buffered/unbuffered bypass
  • increased the wet signal headroom by about 6 dB
  • added the low battery indicator
  • reduced the wet signal level slightly to make it easier to add "just a touch" of reverb

The v2b version can be differentiated from v2a version by the label on the bottom of the pedal or on the box, which indicates how to change the switchable bypass. Or, if no label is present, then you have v2b version.

With respect to the version 2b, version 3:

  • adds trails bypass
  • improves Mix knob taper: ultra-fine control from "just a touch" of reverb to 100% wet with no volume loss
  • adds variable headroom control for line level use at lower Mix knob settings
  • removes battery capability
  • removes switchable buffered/unbuffered bypass
  • has a lower retail price

With respect to version 3, version 4:

  • adds a Tone knob
  • changes the footswitch to a "soft" switch
  • adds selectable trails/normal/two-stage bypass
  • adds an option for true bypass


Can the two channels of a stereo pedal be used as discrete mono?

The two dry signals are discrete but the effect signals are not. Therefore, they cannot be used as discrete mono.

Do your pedals change the phase of the input signal?

Of course not. That would be silly.

Do your pedals digitize the dry signal?

No. The dry signal remains analog.

How are your pedals assembled?

We use modern assembly techniques. We do not use "hand-wiring," because it is prone to human error. We produce consistent, reliable results using automation and strict procedures.

All manufacturing labor is performed locally in Orange County, California.

What is the sample rate / bit depth / processor speed?

There are certain specifications we do not publish, because they have little-to-no bearing on sound quality or performance. Some manufacturers tout these numbers, but we know from vast experience that bigger numbers rarely translate to better sound. Publishing these numbers serves no purpose other than to mislead or confuse the customer:

  • Sample Rate — bigger is not necessarily better, especially once you go beyond the frequency bandwidth of the input signal or of human hearing
  • Bit Depth — nearly all digital gear is at least 24-bit these days
  • Processor Speed means little, because most modern digital signal processors can do several parallel operations simultaneously. In addition, an elegant, optimized algorithm will often perform more efficiently than a poorly-coded, inelegant algorithm on a faster processor.

The specifications that do matter are published in our User Guides:

  • Frequency Response
  • Latency: note that an analog dry path means no latency
  • Total Harmonic Distortion
  • Signal-to-Noise Ratio

And of course the most important "specification" is how it sounds. Only you can be the judge of this.

Why are your pedals so light-weight compared to some others?

Many people confuse weight with quality; a heavier object somehow feels more durable or valuable. Some pedal builders take advantage of this psychological trick by using a heavier enclosure. For example, some use die-cast zinc instead of aluminum. There is little difference between the material properties of these two metals (at least for their use in pedal enclosures), but zinc weighs twice as much.

We think that if you are carrying a pedal board around, especially a large one, you might not like this. So, we don't artificially weight our pedals.

Will you customize my pedal?

We do not perform custom modifications of any kind. However, we do welcome any comments or suggestions you have that may help with future pedal development.
