PRODUCT DESCRIPTION

The new SEM has the same single-voice analog circuit design as the original - 100% analog!

SEM with patch panel connections to internal inputs and outputs.

Originally released in 1974, the SEM is one of the classic discrete analog synths, with a huge, three-dimensional "fat" tone that must be heard to be believed. Tom's reissue cuts no corners- the circuitry is almost identical to original units. The only component changes were made due to unavailable parts, but the great tone has not been affected. No digital voice circuits, or thin-sounding analog "voice chips" here- only genuine hi-fi fat analog goodness.

This version includes a panel with 33 direct-access patch points on 1/8" jacks, transforming the SEM into a powerful "mini-modular" synthesizer. Not only does this allow tremendous voicing flexibility when used

 standalone, it allows easy interfacing with modular synthesizers or additonal SEM modules for limitless potential.
