The Dunlop JCT95 Justin Chancellor Cry Baby Wah is a signature wah pedal built for Tool bassist Justin Chancellor, and it is unusual among Cry Baby models in carrying three effects in one enclosure: a wah, a second filter mode, and a fuzz. Dunlop's buying guide describes it as combining "three of Justin Chancellor's epic effects into a single pedal"1. MusicRadar notes it is aimed at bassists, features two filter modes, uses a sprung treadle like the WTF, and includes a fuzz circuit2.
Three effects in one pedal
The pedal's two filter modes cover different ground. Dunlop describes the modified Cry Baby wah mode as sounding lush and aggressive, while the U.K. Filter mode, inspired by the tone circuit on Chancellor's bass, sounds thick and voice-like1. For a bass player, that second mode is the distinguishing feature: it is drawn from how Chancellor himself shapes his instrument's tone rather than from a guitar wah voicing.
On top of the two filter modes sits a vintage U.K.-style fuzz. Dunlop says it can be paired with either mode or operated independently, so the fuzz works as a standalone effect when the wah is not engaged1. Separate controls customize the intensity, level, and EQ of the fuzz mode1.
Controls
| Control | What it does |
|---|---|
| WAH VOL knob | Sets overall volume of Wah mode3 |
| Volume and Q controls | Customize the two rocker modes1 |
| Fuzz intensity, level, and EQ | Customize intensity, level, and EQ of fuzz mode1 |
The Q control shapes the peak of the wah filter, and together with the Volume control it lets you tailor how each rocker mode sits in your signal. Dunlop's manual documents the WAH VOL knob specifically as setting the overall volume of Wah mode3.
Power and battery
The JCT95 is powered by one 9-volt battery, accessed via the bottom of the pedal, according to Dunlop's manual3. Undo the bottom plate to reach the battery compartment, swap the cell, and refit the plate.
Price and where it sits in the Cry Baby range
Dunlop's own product page lists the JCT95 at $315.99 USD as of 2026-10-254. MusicRadar's 2026 coverage lists it at $3292, so the two published figures differ; the maker's page carries the newer figure. That places it well above a standard Cry Baby GCB-95, which is expected given the added fuzz circuit and second filter mode. Players comparing signature models might also look at the Dunlop Cry Baby DareDevil Fuzz Wah, another Dunlop wah that pairs a filter with a fuzz, or the Dunlop CBM105Q Cry Baby Mini Bass Wah for a compact bass-oriented alternative.

Questions
Does the JCT95 have a built-in fuzz?
Yes. Alongside its two filter modes, the JCT95 carries a vintage U.K.-style fuzz circuit. Dunlop describes it as a fuzz that can be paired with either wah mode or operated independently, so you can run the fuzz alone, the wah alone, or both together. Separate controls let you customize the intensity, level, and EQ of the fuzz mode.
Can the JCT95 fuzz be used on its own?
Yes. Dunlop's buying guide describes the fuzz as a vintage U.K.-style circuit that can be paired with either of the pedal's two rocker modes or operated independently. That means the fuzz works as a standalone fuzz pedal when you do not want the wah engaged, and it can also be stacked under either wah mode.
What is the U.K. Filter mode on the JCT95?
The U.K. Filter is one of the JCT95's two filter modes. Dunlop says it was inspired by the tone circuit on Justin Chancellor's bass and describes its sound as thick and voice-like. It sits alongside a modified Cry Baby wah mode, which Dunlop describes as lush and aggressive. The two rocker modes can be customized with Volume and Q controls.
How do you change the battery in the JCT95?
The JCT95 is powered by one 9-volt battery, and according to Dunlop's manual it is accessed via the bottom of the pedal. Undo the bottom plate, swap the battery, and refit the plate. The manual dates from 2021, when the pedal was documented.
What do the Volume and Q controls do on the JCT95?
Dunlop says the Volume and Q controls let you customize the pedal's two rocker modes. The manual specifies that the WAH VOL knob sets the overall volume of Wah mode. Q, in wah terms, sets the width and intensity of the filter's peak, so the two together shape how pronounced each mode sounds.
