Perception Custom 4 String

Synonymous with the needs of the journeyman bass player, delivering outstanding tone, feel and balance, the Fret-King® Perception™ Custom speaks to the bass player’s love of tradition and introduces thoughtful innovation.

One of the electric bass’s most enduring styles the Perception™ has been the instrument of choice for independent thinking bass players for nearly three decades. The enduring style, superb balance, comfort and feel of the Perception™ are exactly what works, with a contemporary twist that remains friendly and comfortable.

Our decades of knowledge in tonewood selection and attention to detail in construction methods, electronics, hardware, and pickups are all crucial in the creation of the Fret-King® Perception™ Custom.


Using either a selected Ash, or American alder body, the Perception body features an extended neck joint and enhanced upper access cutaways which coalesce to maintain the Perception Custom's elegance and purity of line and ensure the foundations of a constructional integrity which provides strength, superb resonance, amazing sustain and a truly epic bass tone, with a superb overall balance which makes the Perception Custom a pleasure to wear.

A 42.5mm Graph Tech® self-lubricating nut is smooth and friction free.


Light oil finished, hard rock Maple neck with classic profile for instant comfort, speed, accuracy, and a luxurious ‘played in’ feel.

Featuring the quite outstanding Aguilar® 4SD-D1 pickups mated to Aguilar’s most flexible active on-board pre-amp design, the 18v OBP-3TK, provides 6dB of additional pre-amp operational headroom and offers three discrete bands of cut and boost at +/-18dB at 40Hz, +/- 16dB 400Hz or 800Hz, with a mini toggle switch to select the mid centre frequency, and +/- 18dB at 6.5 kHz.
