All DCW "Flight Series" pedals are authentic, vintage-based recreations of classic designs. The Flight 4049 is a recreation of the original Red Llama circuit with all the vintage specs you are looking for. The Red Llama has been reissued with a tone knob and other tweaks through the years, but the Flight 4049 is based on the original circuit. The pedal has been recreated including the same CD4049 chip (hence the name) and that big, beautiful 330uF capacitor and heavy low end. A bit of grit, all the way up through fuzzy drive with loads of volume available, just like the original from over 25 years ago!
