ADC Sound Shaper 110 MKII ()
A graphic EQ that shows up on collectors' radar, even though its story is still only partly pieced together.
Overview
Most vintage graphic equalizers sit behind a preamp and get forgotten. The ADC Sound Shaper 110 MKII is also listed as the ADC Sound Shaper One Ten Mark II Stereo Frequency Equalizer. It keeps turning up in odd corners of the market, with prices that run from garage-sale curiosity to "wait, is this rare now?" territory. It's a stereo graphic equalizer and part of the ADC "Shaper" series, though exactly where it sits in that lineup is unknown. It is not a speaker, despite some listings trying to sell it as one. Those listings are either confused or counting on someone not reading past the brand name.
Owners report units with LED level meters and gain controls. The core layout appears to be 2 x 12 bands, which means 12 sliders per channel. That's not groundbreaking by modern standards, but in its day - whenever that day actually was - it would have offered fairly detailed tonal shaping for a stereo rig. Who it was aimed at, studio tweakheads or living-room listeners trying to tame a boomy corner, isn't known. There's no data on who used it, how it sounded, or whether it was a breakthrough or just another box in the rack. There are no reviews, no testimonials and no service notes, other than that the original manual is now considered a "rare item" by collectors. 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 sells 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. That suggests a realistic market value for a clean, functional unit. Condition matters. One listing noted "Excellent Condition! Original Manual Included," which might explain the premium. Finding an original service manual is tough, with Worthpoint labeling it a "Rare item." Replacement parts like slider knobs are still available, which helps keep units alive when wear and tear catch up.
