The Tech 21 SansAmp Character Plus Mop Top Liverpool is a two-in-one preamp pedal pairing a Vox-style amp emulation with a Rangemaster-style treble booster, effectively a stompbox within a stompbox. The amp side covers top-boost AC30 territory at two gain profiles, while winding the character control full up thickens the low mids for a non-top-boost AC30 voice. The booster is flat at noon and adds up to twelve decibels of treble boost clockwise for the brighter, edgier sixties and seventies lead sound. It works as a standalone preamp into a power amp, mixer or interface, or in front of an existing amp. It suits British invasion, jangle, classic rock and Brian May style lead tones, where chime and cutting upper midrange matter more than saturation.
The Vox VTB-1 is a modern silicon reinterpretation of the classic Dallas Rangemaster treble booster, heard on recordings by Rory Gallagher, Brian May, and Marc Bolan in its original germanium form. Built around a hand-selected, precisely biased silicon BC109 transistor rather than an unpredictable vintage germanium device, it delivers a smooth onset of drive, singing overtones, and the classic treble-booster cleanup that comes from rolling back the guitar volume, spanning from near-clean touch-sensitive breakup to a vicious, cutting edge. It widens the sweet edge-of-breakup zone compared to vintage units while staying dynamically sensitive and quiet, though pushed to its highest gain it can turn sizzly. It suits blues and classic rock players wanting authentic vintage treble-booster character and touch response without the inconsistency of an original germanium unit.
