The most conventional of the Mr Black pedals on recent test, the ThunderClaw shoots for big, amp-like high-gain distortion, and boy, does it score.

"It's ace for Mastodon with a bridge humbucker, while flicking over to the neck is instant Kyuss"

A silicon fuzz-like palm-muting response means it's not our first pick for classic metal, but there's an alt/stoner vibe here that's ace for Mastodon with a bridge humbucker, while flicking over to the neck is instant Kyuss.

There's plenty of versatility, too, thanks to an active EQ circuit: pushing the bass and treble gives the TC a fuzzy RAT-like edge.
