Dunlop Slash Cry Baby Classic

Dunlop Slash Cry Baby Classic review: signature sound meets classic reliability

Key facts and build quality

The Dunlop Slash Cry Baby Classic, released in August 2012, is Dunlop's signature wah pedal modeled after the tone of Slash, the legendary lead guitarist of Guns N' Roses. Priced at $195, it comes in a single-piece configuration and features a steel housing finished with a worn, vintage-style look. The pedal includes a distinctive "Slash" signature on the tread, contributing to its stage-friendly aesthetic.

This pedal is equipped with a custom-wound inductor coil tailored for a prominent and musical midrange. The hardware leans toward heavy-duty: the footswitch is robust, true hardwired bypass ensures signal purity, and there are prominent blue status LEDs on both sides of the base, making it easy to confirm activation even on dim stages. The pedal accepts standard 9-volt batteries or a 9-volt DC power supply (center negative, 2.1 x 5.5 mm barrel, not included). Connectivity is limited to standard 6.3 mm mono input/output jacks.

Tonality and frequency range: what makes the Slash Classic stand out

The custom coil is tuned for enhanced low frequencies and offers an expanded dynamic range compared to standard wah designs. Owners consistently describe the Slash Cry Baby Classic's voicing as warmer and more mid-focused than generic wah models. The pedal deliberately avoids piercing high frequencies, resulting in less harshness and a smoother, fatter tone, especially effective for rock and high-gain styles. The sweep from heel to toe is expressive: bass-heavy at the heel, moving to a vocal, harmonically rich mid bump, and finishing with highs that are clear but never shrill.

• Lush midrange sweep: The pedal's core is a pronounced, singing midrange perfect for expressive solos, especially with distortion.
• Smooth top end: Unlike some wahs that become brittle, the Slash Classic's high register remains musical, favoring a creamy lead tone over treble bite.
• Wide dynamic range: Users report a broad sweep, responding well to fast, aggressive pedal movement without dropping out or thinning the signal.

For fans of the classic rock wah sound, think "Sweet Child O' Mine", this is the heart of the appeal. The wah voice is instantly familiar to those who recognize Slash's signature sound, but it's also praised for balancing well in a band mix and avoiding the volume dips found in some older wah pedals.

Practicality and stage readiness

The steel enclosure feels as solid as advertised and is notably hefty, which prevents slipping during energetic performance. The actuating mechanism is praised for staying put at any angle, meaning you can leave the pedal set for static filter effects without it returning to neutral on its own. Operation is straightforward: press at the toe to engage or bypass (with the true bypass switching), and blue LEDs confirm each state. The switch is neither too firm nor too sensitive, making activation easy whether standing or (less ideally) seated, the latter can be challenging, as some owners found more effort is required for the switch compared to playing on foot.

The status LEDs are a real upgrade for live players, especially on dark stages, and ensure you never lose track of whether the effect is active. True hardwire bypass means there's no signal degradation in off mode; there's also no volume drop when engaged, which fixes a common complaint with standard issue models.

Typical scenarios and musical fit

The Dunlop Slash Cry Baby Classic handles both clean and highly saturated signals with authority. On clean amplifiers, it delivers a vocal, expressive effect; when fed into distortion, it becomes creamy and mid-heavy rather than shrill, which is exactly what players aiming for Slash's tone or similar classic/hard rock lead sounds will appreciate. Blues and more aggressive funk styles also benefit from the pedal's "throaty" mid character, but those wanting a sharp, quacky funk wah might find the top end slightly subdued.

Musicians switching from older Cry Baby models or more neutral wahs often report the Slash model feels more inspiring to use, with a usable, musical sweep in every position. The fixed voicing means there are no on-board fine adjustments (unlike "Q" series or multi-control wahs): what you get is the carefully dialed-in Slash signature sound. For those after maximum tweakability, this could be a downside; for plug-and-play players, it's an advantage.

Drawbacks, quirks, and use notes

• Price: At $195, it sits above entry-level wahs and non-signature models, but the cost is reflected in the build and design.
• Voicing: The warm, mid-forward sweep is not ideal for ultra-funky, bright styles, this is a rock wah first and foremost.
• No external adjustment: The pedal lacks tweakable Q/frequency controls and has no built-in boost or auto-return features.
• Minor quirks: Some users note a short throw on the axle and slightly more effort required for activation when sitting.
• Background noise: Some report a bit of extra noise when engaged, but not to a level that obscures the effect, especially in band settings.

Summary: who should choose the Slash Cry Baby Classic?

If you want a stage-ready, solidly built wah pedal tailored for powerful, expressive rock and lead work, the Dunlop Slash Cry Baby Classic is a top contender. Its lush sweep, thick midrange, true hardwire bypass, and live-friendly LEDs all live up to its reputation. While not the most flexible for tinkerers or those seeking super-bright funk tones, this pedal excels at what it sets out to do: deliver the charismatic, creamy wah sound that defines Slash's playing. Even players with no particular affinity for Guns N' Roses often prefer this signature wah's voice and reliable construction over more general-purpose models. For anyone wanting a plug-and-play wah with unmistakable character and zero setup issues, it's hard to beat.
