How many pedals can the Truetone 1 SPOT Pro CS6 power?

6 isolated outputs and 1600mA of DC, checked jack by jack against 211 pedals at their own voltage.

Plan a board on the Truetone 1 SPOT Pro CS6

02The short answer

Up to 6 pedals, one per output, from 1600mA of DC.

Built for: A six-pedal board with two hungry digital pedals on the 500mA jacks, two jacks that switch to 18V and two that switch to 12V.

  • 152 of the 205 powered pedals in our database run on any jack here at their voltage, even its smallest (100mA at 9V).
  • 48 need one of its larger jacks, up to 500mA at 9V.
  • 1 draw more than any jack here carries at their voltage.
  • 4 pedals have no published draw: read the figure off the label and the calculator finds the jack that carries it.
  • 4 passive volume pedals take no jack at all.
  • The Eventide H90 Harmonizer runs from its own 12V adapter, off the supply.
  • The Electro-Harmonix Deluxe Memory Man runs from its own 24V adapter, off the supply.

03The jacks

Per-jack ratings as the manufacturer publishes them. A jack carries a pedal when it offers the pedal's voltage and its rating at that voltage is at or above the pedal's draw.

OutputJacksVoltagemA per jackPedals each jack carries
Jacks 1-229V500mA196 of 201
Jacks 3-429V / 18V100mA152 of 201
Jacks 5-629V / 12V200mA166 of 201
Total DC61600mA

Every output section is isolated, so a digital pedal on one jack does not share a ground with the pedal next to it. “Pedals each jack carries” counts the 201 powered pedals in our database with a published draw, each at its own voltage. Pedal figures are typical published draws; check each pedal’s label for its voltage and polarity before you plug in.

04Where the big pedals go

The pedals in our database that need more than its smallest jack at their voltage, highest draw first.

Per-jack ratings transcribed from Truetone’s published spec. Outputs 3 and 4 switch between 9V and 18V; outputs 5 and 6 between 9V and 12V. Truetone says its 1 SPOT supplies handle more current than the output labels suggest; this planner holds every jack to its printed rating. Truetone spec page.
