Filter-Based Preamp for Bass Guitars

A modern design paying tribute to the original Alembic filter

Drop-in Alembic Replacement

Sounds and feels exactly like 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 trouble with just about any bass (not just Alembic), and also in outboard enclosures.

High Quality Pot

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

3-position Q Switch

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