Erich from Dice Works
HS-1 and HS-2 emerald are both the same Hornby-Skewes booster based on the Ritchie Blackmore sound. When it comes to effects shrouded in mystery, this one is near the top of the list. ALL of the schematics you see for it are wrong (and there are a bunch out there). I have spent the better part of 6 months collaborating with people in California and England who owned originals, and I have it dialed in. I have also added several new options (different drive and tonal options). The HS-1 is the "Smoke on the Water" tone, and cleans up REALLY well with your guitar volume.
This is a version of Blackmore's modded Hornby-Skewes unit. It's modded to produce the signature "Smoke on the Water" tone (so it has more mids, volume, and drive than the original treble booster circuit). It's battery power only, no AC power- it's kind of like a Fuzz Face in that doesn't work well with AC power. It will also clean up extremely well with your guitar volume.
Features include true bypass operation, silicon transistor, metal film resistors, and poly caps (for quiet operation).
