Rafferty HPF Pre 2 Bass Preamp / Adjustable High Pass Filter / Phase Switch Custom Color

• Due to high demand - there is currently up to a 3 week build time on this unit (each unit built to order). 

• All HPF Units are sold by default in white with graphics labelling controls, as seen in the first image. If you are interested in other colour/graphic options, please contact me!

If you are here you probably already know what this is. The HPF Pre-2 is a very handy utility tool, predominantly for Bassists. This little box is a preamp with controls including an adjustable high pass filter, independent volume control, and a phase switch. 

This box is a great tool for some sound related issues bass players can experience using amps or PA systems, by tuning out subharmonic thump and wool, and focusing sound in general.

It has a filter cutoff adjustable from 35hz to 150hz, and runs using a standard 9v centre tip negative supply.

Now includes internal 9v Battery clip as standard.

Custom artwork/paint jobs available upon request.
