Super Rare item!
 
The SPL Tube Vitalizer is a mythical audio processor that has been out of production for two decades. It has very distinct and unique audio processing qualities never seen in any subsequent gear, making it a sought after analog hardware. Low frequency demasking, harmonic processing, and analog stereo are some of features.
 
This unit has been in our studio for some years and has been in perfect care. It is perfectly functioning; however, it will need some minor servicing on one of the tubes (or replacement of tube) as audio amping from one of the tubes is a few dbs. off optimum level plus slight calibration for one of the attenuator knobs in terms of positioning.
