Tinsley Audio is a boutique effects pedal company based in Austin, Texas, founded and operated by Dustin Sears, a guitar tech who previously built univibe-style pedals under the Shin-ei Vibe Bro banner. The shop is a small, hand-built operation focused on recreating the modulation sounds of the 1960s, and each unit is assembled to order.

The company is best known for the Sir Henry, a univibe and rotary-style modulation pedal designed around custom-tuned photocells intended to reproduce the liquid, swirling character of the original Shin-ei Uni-Vibe circuit. The Sir Henry is sold direct through Tinsley Audio and has been carried by boutique retailers such as Rudy's Music in New York.

The Sir Henry has found favor with touring blues and rock guitarists, with Doyle Bramhall II and Kenny Wayne Shepherd among the players cited as users of the pedal.

Tinsley Audio has 1 product cataloged on Equipboard, including Univibe & Rotary Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock, Blues, and Funk / Soul. Notable users include Doyle Bramhall II and Rhett Shull.
