Introducing the DirtBox, a phantom powered distortion effect box for microphone level signals! Just plug any microphone into the DirtBox to get amazing analog distortion tones.


Building on the success of the DrAlienSmith DirtMic-01, we've taken that very same circuit and put it in it's own enclosure. Now any microphone that's plugged into the DirtBox becomes a distorted beast. The two DirtBox transformers match your Low Z mic to the distortion effect and then back again to the mic preamp so it's a simple solution that packs a lot of punch.


The circuit has been designed to run off 48v phantom power so no batteries or power supplies are needed. Simply plug in a mic into the input, then plug the DirtBox output into any mic preamp and turn the phantom power on. The top panel LED will light up with the presence of phantom power. The amount of distortion on the DirtBox is controlled by the ‘pre-gain’ volume pot, the red knob. Turn the gain right up to 10 to capture unique, dirty flavors from any sound source or try lower gain settings for a more subtle tones.


A Balanced Y cable now comes standard with the DirtBox and it unlocks two extra features, the first is the ability to capture a clean and a distorted signal from the one source. By using the Y Cable you can split the signal into 2 and use one split for a clean sound and the other split for the DirtBox and a distorted signal. The two signals will be in phase and can be mixed together to your taste. The second feature unlocked by a Y Cable is the ability to use a condenser mic with the DirtBox. By turning on phantom power for both the clean and distorted preamp inputs, the DirtBox and the condenser mic will both be powered.


The DirtBox has been designed to be a recording studio tool but there is some potential to use it for live performance. If you use a Cardioid or Supercardioid microphone on a vocal and you keep the gain levels low you can reduce the potential for feedback. Also if you use the Y cable you can send the clean split to the monitors and the distorted split to the front of house PA which will again reduce the instance of feedback. However live distortion is always tricky so you'll have a better chance of success if you have a smart sound person and you keep the on stage volumes low.


Search for DrAlienSmith DirtBox to see lots of videos demonstrating how the DirtBox sounds.


As of September 2021, the DirtBox has a new red enclosure but its just a cosmetic change, inside it is identical to the original white DirtBox.
