Delano Control Pot 50kB + 250kA

This special double function potentiometer design is for combining passive tone control with active treble control in a single shaft unit. In active mode the 50KB section with center click is working, in passive mode you will have a 250KA tone roll-off from center click position through anticlockwise. From the center click to full clockwise, the passive tone has no effect on the tone, just like a typical passive tone control turned up full.

A .033uf ceramic disk capacitor is already installed on the pot for the passive tone section. Threaded section is M7x0,75, length10 mm, solid shaft is 6 mm diameter, length 10 mm. 16 mm body cavity depth are required.

This pot typically comes supplied with Delano Hybrid pickups, but is available now separately for use with Delano Sonar 2 and 3 model preamps.

(This pot will also work with other preamps that use 50k Linear taper pots with a center detent for the treble control like: Aguilar OBP2 & 3, Bartolini NTBT & NTMB, Nordstrand 2B & 3B, Noll TCM 2, 3, 4, and others.)

(This is the same potentiometer as BBG 9089 Noll P 1030 Passive Tone Control, only the Noll tone control has a .047uf capacitor.)
