Thanks to its tube gain section, the T1M preamp module has a warm and
full sound that doesn’t cloud the instrument’s tone but glorifi es its harmonics,
reproducing every detail with exceptional definition. It’s perfect for anyone
who wants tube warmth without distortion.

The S1 preamp module features the standard-setting sound of the top-selling Little Mark II and SA 450 amplifiers. It’s a solid-state preamp that faithfully reproduces the tone of whatever instrument you play through it, without adding any coloration. The simple features include an unbalanced input (for both passive and active basses), gain control and clip LED.
