New Opto Tremolo In Development

After countless modifications and testing more than a dozen of different resistive optoisolators I am finally at a point, where my new Vactrol-based opto tremolo circuit sounds just awesome. I already sent a first prototype to Styrian guitar player “Sir” Oliver Mally, who confirmed my assessment: this is something big. I’m really looking forward to bringing this little sound monster to market in the next weeks!

Songbird FX - Bluebird Drive Si and Ge - Silicon Germanium Clipping Stage Diodes Overdrive Pedal Rechargeable Micro-USB

‘Bluebird Drive Si’ (silicon clipping stage) and ‘Bluebird Drive Ge’ (germanium clipping stage)

The Bluebird Drive is available in two versions:

  • Bluebird Drive Si:

    Legendary 1N4148 silicon clipping diodes deliver a great range of sounds, going from clean boost to singing leads.

  • Bluebird Drive Ge:

    Rare soviet D9D germanium clipping diodes (NOS) give you a sound that goes from warm overdrive to fuzzy leads. The asymmetrical clipping stage combines the characteristical low clipping threshold of germanium diodes on the positive half wave with higher output level on the negative half wave (achieved by connecting a silicon 1N4148 in series to the D9D).
