"The Radial J+4 sounds great, is well built and practical. It seems like somebody actually thought about making a good product and then actually did... Great stuff!"
"I am using the Spaceheater by Radial as a main feature on vocals. It provides old school distortion on the bass and some warmth peppered on the strings. I like the vibe of the Spaceheater and use it on my sessions."
The Radial J+4 is a -10dB to +4dB stereo preamp that lets you boost a low output unbalanced signal and interface it with a balanced professional audio system.
