Filter-Based Preamp for Bass Guitars

An improved, modern version of the original Alembic filter preamp

Drop-in Alembic Replacement

Sounds and feels exactly the same as the original Alembic filter preamp, while having even lower noise and much lower power consumption. Features Alembic-compatible Molex headers.

More Compatible

Works without any headaches with just about any non-Alembic basses, and also in outboard enclosures.

High Grade Pot

(ok, not that kind!). Dual reverse log, sealed, conductive plastic pot, rated for 1,000,000 cycles. Arguably better than the already very nice Clarostat pot Alembic uses.

3-position Q Switch

Quality, major brand switch with gold plated contacts. Designed specifically for switching low level signals.
