Radial Space Heater

The Space Heater 500 from Radial Engineering is a studio quality tube distortion built in the 500 series format. It produces everything from gentle warm breakup to fat heavy distortion.

Designed to be used with the Radial Workhorse, or any 500 series rack or case, the Space Heater 500 is built around a 12ax7 tube. Featuring controls for Level, Drive, Heat (voltage starve selection), High Cut, Lo Cut, and Pre/Post/Off EQ selection, the Space heater 500 series allows users to dial in the perfect amount of tube warmth or rich harmonic distortion.
