Pedaltrain VOLTO Frequently Asked Questions

Is VOLTO right for me?

VOLTO is for everyone who loves pedals. VOLTO was designed for musicians who desire a very portable, light weight, “unplugged” power supply. VOLTO is sleek, fun, and powerful. However, VOLTO is not the right solution for every musician or every pedal. Read on to learn more.

Attach and Change Power Adapters

VOLTO is packaged with a USB charging dock and four different adapters for worldwide use: USA, EU, AUS, and UK. VOLTO is shipped from factory with the EU (European) adapter attached to the USB base. Changing this adapter is easy. Please refer to this article for a video on how to change the adapter.

Initial Charge Time

VOLTO is a powerful lithium ion battery. VOLTO requires approximately six (6) hours of uninterrupted charging to ensure it is fully charged. Owners should not assume VOLTO is shipped with a full charge out of the box.

Charging Process & LED Indicators

During the charging process, the three LED indicators may illuminate, giving the user the impression the device is fully charged. Although these LED indicators do tell you that VOLTO has a strong residual charge, they do not necessarily indicate a full and complete charge. Be sure to charge VOLTO for six (6) hours to completely maximize VOLTO’s stored charge. You should see the top light blinking during charging. 

Recharging

VOLTO requires six (6) hours to completely recharge its powerful lithium ion battery.

Polarity

Volto is tip negative. Most 9-volt pedals are tip negative. If you have a tip positive pedal you can buy an inverter adaptor. Pedaltrain does not sell polarity conversion adapters, but there are many available online.

Battery Life

VOLTO is a powerful 2000 mA lithium ion battery that can power a typical five-pedal Pedaltrain for up to 36 hours of continuous use. However, VOLTO performance varies on a number of factors:

  • Quality of stored charge
  • Draw of your pedals
  • Type of your pedal
  • Use of your pedals

VOLTO can have amazing battery life when powering pedal varieties that use a standard 9-volt battery. Just about every analog overdrive, phase, flange, delay, compression and tremolo pedals fall into this category. Tuners too.

Certain pedals, like high-fidelity digital delays and reverbs, draw very large amount of power and are frequently in an “always on” mode. “Always on” can mean two things: a) the player leaves the effect engaged all the time, or b) the pedal is drawing current regardless of whether or not the effect is engaged. While VOLTO can power these pedals, it is important to note that VOLTO was not designed to power these types of effects as a primary design function. VOLTO’s battery life will be diminished using the pedal types.

Simultaneously Charging VOLTO and Powering Pedals

VOLTO can simultaneously power your pedals and charge its lithium ion battery. That said there are some nuances you should be aware of:

  • VOLTO requires a residual charge to perform its simultaneous charging/powering feature.
  • If VOLTO is fully discharged it will not recharge and power your pedals. Instead, you should recharge VOLTO according to the instructions above.
  • The draw of your pedals must not exceed the electrical requirements to charge VOLTO.

If your pedals draw more than the amount required, VOLTO will operate in a net deficit and, by design, VOLTO will default to powering your pedals and forego charging itself.

Combining Outputs for Higher Output

VOLTO’s outputs cannot be combined to boost or modify its output. Doing so may damage your VOLTO and will void its warranty. Do not attempt to combine the dual 9v outputs on your VOLTO.

Isolated Outputs

VOLTO’s two 9-volt outputs are not isolated. Some pedals require their own isolated ground to minimize noise. VOLTO can power these pedals, but you may experience a higher noise floor using VOLTO. If you have many pedals, on a large Pedaltrain, you may want to consider a Powertrain 1250 which is designed for more demanding applications.

Noise

VOLTO is designed to have a low noise threshold. If you feel that your VOLTO is generating noise above what is reasonable, check your pedals one by one to find the offender. Are all your pedals tip negative? Are your pedals 9V and in good working order? Any DIY or esoteric, untested, uncertified electronic devices? If you are still having problems, please contact us here.

Which output should I use?

VOLTO has two 9-volt outputs. You can use one or the other or both. Experiment to understand which makes your pedals sound best, with the lowest noise.

Environments effects and fluorescent lights

Like many musical instruments and accessories, VOLTO can be affected by environmental factors (even when it is not plugged into the AC current from the wall). We have observed that certain lights, like fluorescent and neon lights, can add trace noise elements to your sound. This is no different than the type of situation you find with single-coil pickups.

No LED Lights/VOLTO Will Not Power On or Off

There are two circumstances by which VOLTO’s LED indicators will not light:

  1. VOLTO is fully discharged and requires a full charge to become operational. Follow the instructions listed above.
  2. VOLTO needs to be reset/restored. We built a surge prevention/safety circuit into VOLTO to protect your pedals from power surges. Simply plug VOLTO into the USB power base for 60 seconds and the system will be reset.

Reset/Restore VOLTO

If your VOLTO needs to be reset/restored simply plug VOLTO into the USB power base for 60 seconds and the system will be reset.

High Draw Pedals

Certain popular pedals, like high-fidelity digital delays and reverbs, draw very large amount of power and are frequently in an “always on” mode. “Always on” can mean two things: a) the player leaves the effect engaged all the time, or b) the pedal is drawing current regardless of whether or not the effect is engaged. While VOLTO can power these pedals, it is important to note that VOLTO was not designed to power these types of effects as a primary design function.

DIY Pedals

DIY pedals are awesome. We have a ton of them at our office. Unfortunately, these pedals are rarely (never) properly tested, shielded, grounded and certified. VOLTO has been properly certified in every country through rigorous (and expensive) regulatory testing. Sometimes these worlds collide. Certain DIY or esoteric pedals may not play well with VOLTO, and create more noise than you are comfortable with.

Does VOLTO work with my pedal(s)?

VOLTO is a 9v center negative 2000mA power supply. If your pedals fit in this window, you are good to go. However, there are just too many pedal combinations and power variations to make a pedal-by-pedal recommendation.

Travel Restrictions/Flying

VOLTO is certified in every country in which it is sold. Just like your laptop, tablet or smart phone, you can travel freely with VOLTO. Bon Voyage!
