Contacta con nosotrosLocomotive Audio WT-Comp (Weight Tank) is a single-channel, soft-knee vari-mu tube compressor designed by St. Louis-based Eric Strouth, drawing on the Universal Audio 175B and the Altec 436A, with some ideas borrowed from Locomotive's own Model 14B. It's the second standalone (non-500-series) tube compressor in the Locomotive Audio range, alongside the Model 14B.
Two characters in one switch
A Smooth/Drive switch changes how the 6BC8 and 12AU7 tubes behave: Smooth gives the sweet, gentle tone typical of classic vari-mu compression, while Drive pushes the tubes toward a richer, more harmonically saturated character. A fixed compression threshold (roughly 3.5-4:1 per the manufacturer's own figures) simplifies control to two main knobs: attack (12-50ms) and release (200ms-2 seconds).
Three steel transformers instead of one do-it-all part
Two transformers in the input stage and one on the output, all-steel construction, build the compressor's characteristically heavy tone. A VU meter tracks gain reduction, a TRS jack lets you pair two WT-Comp units for stereo work, and a hardwire bypass lets you compare raw and processed signal at any moment. The "Weight Tank" name points to the sonic heft the circuit adds to a signal, especially useful on vocals and bass guitar, where density and presence in the mix matter most.
