The Inspector Claws-o is a limited artwork version of the Rattler ltd from JAM Pedals, a Greek pedal maker known for its hand-finished enclosures. It is a distortion pedal, listed by the maker as "NOS DISTORTION", built around a rare component set: an NOS LM308AH metal-can op-amp, carbon-composition resistors, tropical-fish capacitors and point-to-point wiring1. The circuit uses symmetrical clipping, which JAM Pedals says gives the Rattler ltd "a smoother, less hairy response than the standard model while retaining full" range authority1.
What sets the Inspector Claws-o apart from the standard Rattler ltd is not the sound but the finish. JAM Pedals describes it as "Same sound, different artwork"2, and notes that "Every limited artwork pedal is a one-of-a-kind hand-painted piece"1. The maker lists custom artwork versions of the Rattler ltd, including this one and the "Achenbach" Rattler ltd, among its offerings3.
Controls
The pedal has three knobs and a toggle switch1.
| Control | What it does |
|---|---|
| Gain | Controls saturation |
| Tone | Shapes the response |
| Level | Sets output |
| Toggle | Selects between two gain ranges |
The toggle picks between two gain ranges: high gain to the right, lower gain to the left. JAM Pedals describes the low-gain mode as "more open, less compressed and cl"oser to overdrive1, which makes the pedal usable as a light drive as well as a full distortion.
Power and bypass
The pedal runs on a 9V battery or a 9V DC, center-negative supply, drawing 6 mA1. That low draw means it can sit on any standard pedalboard supply without issue. Bypass is true bypass, so the circuit is out of the signal path when off1.
The listed price is £464.00 GBP including tax, as given on the maker's product page on 25 October 20261. Because each unit is hand-painted and one of a kind, the appearance of any individual pedal will differ from photographs of other units.
Where it sits in the Rattler family
JAM Pedals builds several versions of the Rattler circuit. The Inspector Claws-o shares its sound with the standard Rattler ltd2, and the maker also offers other custom artwork versions such as the "Achenbach" Rattler ltd3. For players after the current mainline version of the circuit, the Rattler 2 is the newer iteration, and the original Rattler remains the baseline. The Inspector Claws-o is for players who want the Rattler ltd sound with a one-of-a-kind painted enclosure.
JAM Pedals offers a 30-day money-back guarantee with a refund no questions asked1.
