The Dunlop MR95LTD Mick Ronson Cry Baby Wah is a signature wah pedal in Dunlop's Cry Baby line, named for Mick Ronson1.
How it works
The pedal has no knobs or switches beyond the pedal itself. Pushing the toe of the pedal down until you feel a "click" turns the effect on and off, and once it is on, rocking your foot back and forth changes the wah effect on your tone instantaneously1. The sweep runs across a wah center frequency range of 500 Hz to 2.25 kHz1.
Power and impedance
The MR95LTD runs on 9 volts DC and draws 750 µA, a very small current draw by pedal standards, so it sits comfortably on any 9-volt pedalboard supply1. Dunlop specifies the ECB003 9-volt adapter or an MXR Brick Series power supply as power options, and the pedal also runs from one 9-volt battery accessed via the underside of the pedal1.
| Specification | Value |
|---|---|
| Power supply | 9 volts DC1 |
| Current draw | 750 µA1 |
| Battery | one 9-volt, under the pedal1 |
| Input impedance | 78 kΩ1 |
| Output impedance | 16 kΩ1 |
| Wah center frequency | 500 Hz to 2.25 kHz1 |
| Bypass | Hardwire1 |
Connections and setup
Hooking the pedal up takes two cables:
- Run a cable from your guitar to the pedal's INSTRUMENT jack.
- Run another cable from the pedal's AMPLIFIER jack to your amplifier1.
Bypass
The MR95LTD uses Hardwire bypass rather than a buffered or true bypass design1. When the pedal is switched off, the signal is hardwired past the wah circuit on its way to the amplifier.
Questions
Is the Mick Ronson Cry Baby wah true bypass?
The MR95LTD uses Hardwire bypass, according to Dunlop's manual. Hardwire bypass routes the guitar signal directly to the amplifier jack when the pedal is off, so the wah circuit is out of the signal path. It is not described by Dunlop as true bypass, but it serves the same purpose: when the pedal is switched off, your guitar's signal does not pass through the wah circuitry on its way to the amp.
How do you turn the MR95LTD on and off?
Push the toe of the pedal down until you feel a click. That click switches the wah effect on and off. Once it is on, rocking your foot back and forth on the pedal changes the wah effect on your tone instantaneously, sweeping the filter across its range as you move.
Where does the battery go in the MR95LTD?
The MR95LTD runs on one 9-volt battery, accessed via the underside of the pedal. Undo the plate on the bottom of the pedal to reach the battery compartment. The pedal can also be powered from a Dunlop ECB003 9-volt adapter or an MXR Brick Series power supply.
What power adapter does the MR95LTD use?
Dunlop specifies the ECB003 9-volt adapter for the Mick Ronson Cry Baby Wah. The pedal can also run from an MXR Brick Series power supply, or from a single 9-volt battery fitted under the pedal.
How much current does the MR95LTD draw?
Dunlop lists the current draw at 750 microamps, an exceptionally small figure. The pedal runs on 9 volts DC, so it is well within the capacity of any standard 9-volt pedalboard power supply output.
Is the Mick Ronson Cry Baby a limited edition?
The LTD in the model name MR95LTD points to a limited edition, and Dunlop announced the pedal in January 2025 at NAMM as a signature Cry Baby reverse engineered from Mick Ronson's original vintage Italian-made wah pedal, developed with producer Bob Rock.
