Blood Donor is a revamped and fine-tuned version of the venerable Katzenkonig with a slew of changes that truly unlocks the circuit’s potential. Adding a carefully selected transistor set that pushes the boundaries of saturation and gain to their electrical limits, giving the old cat a little more fur and bite. The noise floor has been trimmed while widening the utility of all controls, giving an increased range of input sensitivity that mimics the volume knob on your guitar. Get into it! And give blood!

Catalinbread has committed to donating 100% of profits generated from sales of Blood Donor pedals to the American Red Cross, so when you purchase a Blood Donor pedal, you’re also helping take care of our country’s most vulnerable citizens.
