PRESS RELEASE: Halcyon Gold Overdrive

We are proud to announce the release of our new Halcyon Gold Overdrive, an adaptive overdrive pedal based on the Klon® Centaur®. The latest pedal to feature our proprietary Adaptive Circuitry, the Halcyon Gold Overdrive’s unique design allows it to adapt its voicing in response to pick attack and volume knob changes. We have gone to great lengths to recreate the Centaur’s famous, mid-forward voicing and the exact characteristics of unobtainable vintage diodes, but also built in some innovative features that go beyond the capabilities of the original. 

The Halcyon Gold Overdrive’s headline feature is its ADAPT switch. This allows the pedal’s mid-forward voicing to fade away as the pedal cleans up from the guitar volume knob, gradually reintroducing the bass and treble frequencies as the signal falls below the clipping threshold. This allows players to move seamlessly between the Centaur®’s coveted mid-forward overdrive and transparent boost tones, without adjusting the controls on the pedal. 

We have made some other additions to this iconic circuit, in the form of the VOICE switch and DRY control. The VOICE switch selects between two flavours of mid hump and overdrive character. The KLN setting is the classic Klon® recipe, with an aggressive mid peak and the clipping characteristics of unobtainable vintage diodes faithfully recreated using modern parts. The MOD setting has a softer overdrive and a broader mid hump which pairs particularly well with single coil pickups and clean amp tones. 

The DRY control lets you adjust the level of the dry signal that makes up part of this classic drive tone, offering independent control over the balance between clean and overdriven signals. The DRY control can be boosted to add body and definition when boosting a low-gain amp sound or turned down to get the most out of this pedal’s higher gain tones, especially when using a clean amp. We have also made improvements to this dry path, changing the overload characteristics when stacking with other pedals, giving you access to even more flavours of drive. 

Built in the UK to the highest standards, the Halcyon Gold Overdrive takes a modern classic and turns it into something even more responsive and versatile, while never losing the character, musicality and sheer power of the world’s most coveted and controversial pedal.
