Small Speaker Overdrive
1/4

Classic small-amp overdrive that cuts through the mix

Few things sound better than a little Class-A valve combo miked up in the studio. The Small Speaker Overdrive (SSO) is inspired by some of our favourite small-amp-in-the-studio tones, from Steve Cropper to Eric Clapton, Duane Allman and Joe Walsh.

The SSO's discrete transistor circuit offers outstanding dynamics, with full control of breakup from just your fingers or the guitar’s volume knob. 

With gain set low, the SSO can be used as a boost, preamp and tone-shaper, with an uncanny ability to open up the sound of your guitar. Driven hard, it mimics the punchy tone and mid-range ‘honk’ of a simple Class-A amp circuit driving a small speaker.

Press reviews

"The Small Speaker Overdrive does something special — sometimes it’s the difference between ‘nearly there’ and ‘just right’ in a recorded guitar sound."

Dave Lockwood, Sound On Sound

"In true Champ style, this is a tone defined by its focus on the top half of the frequency spectrum… and, we ought to mention, by its superbly natural responsiveness to changes in pick attack and guitar volume."

Richard Purvis, Guitar.com

"The Small Speaker Overdrive's name and the Champ associations fail to do justice to how large and alive it sounds and feels tethered to a bigger amp."

Charles Saufley, Premier Guitar
