CopperSound adds Iris compressor and Kingpin overdrive mini pedals

July 12, 2023 · 3 sources

CopperSound released the Iris Optical Compressor and the Kingpin Germanium Clipper Overdrive as additions to its mini pedal series, according to Guitar Pedal X, which wrote that the maker "doubles down on Mini Pedals with the release of its Iris Optical Compressor and Kingpin Germanium Clipper Overdrive"1. The Iris is listed on CopperSound's site at $149.002.

The Iris is an optical compressor built around what CopperSound describes as "an all-original optical circuit built around a uniquely biased, audiophile-grade op-amp and optical network"2. It has two controls: a Volume knob and a three-position Compression Toggle. CopperSound says the toggle sets three levels of compression, "from a gentle polish that sweetens your sound to a full-on, aggressive squish that makes your solos explode"2. Delicious Audio described the switch as setting the compression ratio across Low, Medium and High settings3.

"Given the space confines of our mini enclosure, paired with the size of traditional through-hole components, we were forced to get creative when it came to designing circuits."

Delicious Audio reported that the Iris uses "only 25 total parts"3. CopperSound lists the following specifications2:

SpecValue
Power9V, 2.1 x 5.5mm center negative
Current draw20mA at 9V
Input impedance1M
Output impedance250K
SwitchingMechanical true bypass
Dimensions3.65" x 1.8" x 2.19"

CopperSound's product page showed the Iris sold out at the time of the listing, with a field to enter an email for restock notification2. The page also listed "Only 3 available" elsewhere2. No price or specifications for the Kingpin Germanium Clipper Overdrive appeared in the available material; Guitar Pedal X named the pedal but gave no details1.

The Iris sits alongside other compact compressors in the compressor pedals category.
