ADC Sound Shaper 110 MKII ()

That rarest of beasts—a graphic EQ that actually shows up on the radar of collectors, even if we’re still piecing together its story.

Overview

Let’s be honest: most vintage graphic equalizers fade into the background, tucked behind preamps and forgotten after the first cable gets unplugged. But the ADC Sound Shaper 110 MKII—also listed in the wild as the ADC Sound Shaper One Ten Mark II Stereo Frequency Equalizer—keeps surfacing in odd corners of the market, tagged with prices that swing from garage-sale curiosity to “wait, is this rare now?” territory. It’s a stereo graphic equalizer, no more, no less, and one that belongs to the ADC “Shaper” series, though exactly where it sits in that lineup remains a mystery. What we do know is that it’s not a speaker, despite some listings trying to sell it as one—those are either confused or counting on someone not reading past the brand name.

Owners report seeing units with LED level meters and gain controls, and the core architecture appears to be 2 x 12 bands, meaning 12 sliders per channel. That’s not groundbreaking by modern standards, but in its day—whenever that day actually was—it would’ve offered fairly detailed tonal shaping for a stereo rig. Whether it was aimed at studio tweakheads or living-room audiophiles trying to tame a boomy corner, we can’t say. There’s no data on who used it, how it sounded, or whether it was a breakthrough or just another box in the rack. No reviews, no testimonials, no service notes beyond the fact that the original manual is now considered a “rare item” by collectors. And yet, people are paying attention: listings on HifiShark show it selling for CA$245 in early 2024, while other eBay auctions stretch the asking price all the way up to $1,500, depending on condition and perceived scarcity.

Collectibility & Value

The Shaper 110 MKII trades in a wide and murky price band—anywhere from $45 for a no-reserve auction lot to $1,500 for a “collector’s specimen” with original packaging and docs. The more grounded data point comes from HifiShark, where two recent sales (Feb 2 and Mar 6, 2024) both settled at CA$245, suggesting that’s a realistic market value for a clean, functional unit. Condition matters: one listing proudly noted “Excellent Condition! Original Manual Included,” which might explain the premium. Speaking of the manual—finding an original service manual is tough, with Worthpoint labeling it a “Rare item,” so if you’ve got one tucked in a drawer, hold onto it. On the bright side, replacement parts like slider knobs are still available, which helps keep units alive when wear and tear finally catch up. Just don’t expect a service manual to walk you through it—good luck finding one.
