The Pedaltrain VOLTO is an innovative solution for the pedal user on the go. Using cutting edge lithium-ion battery technology we have designed an efficient and super quiet alternative to traditional AC powered options. The Volto has two 9 volt outputs which are capable of providing a total output power capacity of 2500mA. The Volto is a great choice for small pedalboards like our Pedaltrain-NANO and MINI. It's also super thin, about the same size as a smart phone. The Volto includes connecting cables and an AC charger with universal plug adapters that will allow you to recharge anywhere in the world. Now your set up can be as clean and simple as one cable from your guitar to your pedalboard and one cable back to your amp, that's it!
