DSM & Humboldt ClearComp

The DSM & Humboldt ClearComp 1078 is an analog compressor pedal from DSM & Humboldt Electronics, built around a circuit approach the maker calls Dynamic Threshold topology, or DT Topology. Where a conventional compressor progressively reduces gain once the signal crosses a fixed threshold, the ClearComp dynamically modifies the threshold while holding the gain reduction fixed. The maker describes the result as a super transparent compressor, and Premier Guitar's press release reported that the design achieves a natural and transparent compression effect with a lower noise floor, less coloring and higher dynamic range than compressors that progressively reduce gain above the threshold¹²³.

What DT Topology does

Most compressors watch a fixed threshold and squeeze the signal harder the further it goes over. The ClearComp's DT Topology works the other way round: it dynamically modifies the threshold with a fixed gain reduction. Delicious Audio's Paolo De Gregorio, writing about the pedal, described it as "a studio-grade, incredibly quiet and transparent compressor," and noted that the approach delivers "a natural and transparent compression effect with a lower noise floor, less coloring and higher dynamic range"².

For a player, the practical claim is that the compression stays out of the way of the tone. The maker positions the pedal as suitable for everything on the instrument's range: Delicious Audio described it as "capable to produce from the sweetest clean jazzy whispers, to the gnarliest of high gain chugs"². If you are new to compressor pedals, the Blend knob and the Threshold switch make this one straightforward to dial in, because both are set by the instrument in front of you rather than by ear alone.

Controls

The Blend knob is the parallel-compression control: with it backed off, some of the unaffected input signal sits underneath the compressed signal, keeping pick attack and dynamics in the mix. The Ratio control spans the full range a player normally needs, from gentle leveling at 1:2 up to full limiting at 1:20¹.

The Threshold switch: HI, MID and LOW

The Threshold switch sets where the dynamic threshold starts, matched to the output level of the instrument plugged into the pedal. The maker's guidance, echoed by Premier Guitar and Delicious Audio, is¹²³:

• HI: high power pickups or active instruments
• MID: regular output guitar and basses
• LOW: low output instruments, like vintage single coils

So a player with a regular output guitar or a standard bass leaves the switch on MID, while a vintage single-coil guitar that needs more help from the compressor gets LOW, and a hot active instrument gets HI. Because the switch sets the starting point of the threshold rather than the amount of compression, it is a set-and-forget control for each guitar rather than something to ride during a performance⁵²³.

Price and availability

Premier Guitar's press release of June 1, 2022 announced the ClearComp 1078 at $299.00 USD, available from early June that year in all stores³. RockBoard's PedalPedia lists the pedal as engineered and developed by DSM & Humboldt, with its circuit type given as analog⁴.
