The Rocktron Classic Wah is a wah pedal positioned by Rocktron as a rugged, lower-priced option for players who want the effect without paying premium prices1. It is a treadle pedal: you rock it with your foot and it sweeps a frequency peak across the guitar's range, from 400Hz with the heel down to 2KHz with the toe down1. Rocktron describes the result as "a sweet, musical, vintage tone"1.
Build and feel
The Classic Wah uses a heavy-duty, all-metal chassis with a tension adjustment for the pedal1. That adjustment matters in practice: the treadle resistance is what your foot fights against, and being able to set it means the pedal can be tuned to a light, fast sweep or a stiffer, more deliberate one. Rocktron also fits its easy-access battery compartment, designed so a battery can be swapped during a gig1.
Powering it
Rocktron lists the power requirement as 9VDC, with a current consumption of 35ma1. The product page also states a 300ma figure under power requirements1, so the two numbers describe the supply requirement and the pedal's actual draw respectively. A standard 9V battery is an alternative, thanks to the accessible compartment1.
For comparison, other classic-style wahs draw from similar supplies: the Dunlop GCB95F Cry Baby Classic runs on 9 volts DC2 and can also run on a 9-volt battery3, and the JOYO WAH-I Classic Wah/Volume takes 9V DC, center negative4.
Where it goes in the chain
Rocktron's guidance is direct: the Classic Wah, like all wah pedals, should normally sit at the beginning of your signal chain, directly from your guitar1. That placement lets the wah sweep your clean guitar signal before it hits overdrive, distortion, or other effects.

Questions
Where does a Rocktron Classic Wah go in the signal chain?
Rocktron says the Classic Wah, like all wah pedals, should normally go at the beginning of your signal chain, directly after your guitar. Placing it before drives and other effects keeps the wah sweeping a clean signal, which is the traditional wah placement.
Can the Rocktron Classic Wah run on a battery?
Yes. Rocktron gives it an easy-access battery compartment designed so you can change the battery during a gig without tools or disassembly. A 9V battery is a practical option if you do not want to run a power supply to the pedal.
What power supply does the Rocktron Classic Wah need?
Rocktron lists the power requirement as 9VDC. The page states a 300ma power requirement alongside a current consumption of 35ma, so any standard 9V DC supply delivering at least the stated draw will run it.
What is the input impedance of the Rocktron Classic Wah?
Rocktron specifies an input impedance of 1M ohm and an output impedance of 1K ohm, with a maximum input of +10dBu. The 1M ohm input is high enough that the pedal does not noticeably load down passive guitar pickups.
Can I adjust how stiff the Rocktron Classic Wah pedal feels?
Yes. The Classic Wah has a tension adjustment for the pedal, so you can set how much resistance the treadle gives under your foot. Rocktron houses this in a heavy-duty, all-metal chassis.
