500-series valve preamp design updated

Sound Skulptor have recently introduced a new 500-series module that delivers a new and improved version of their valve-based mic preamp. Equipped with high-quality transformers and sporting a new high-pass filter, the MP566-II employs a dual-triode valve and draws its inspiration from a selection of classic 1960s designs.

The overall design remains the same as the original module, but with the new variable high-pass filter taking the place of the toggle switches that occupied the centre of the front panel; the preamp’s pad, polarity and phantom power functions are now handled by a trio of buttons that sit to the right of the main controls. A pair of large pots take care of gain and output level control, and there’s a quarter-inch input that can be used to connect instrument-level signals.
