We've been using Noll electronics for years, they're reliable, easy to install, easy to use and sound great.
NOLL ONBOARD EQ TCM 2
A compact dual-band equalizer, the encapsulated version of the module allows variable and easy-to-install mounting and provides secure electrical isolation. Bass and treble can be raised and lowered 15dB by potentiometer with center click. The EQ is powered by a 9V battery and can be combined with all passive and active magnetic pickups.
NOLL ONBOARD EQ TCM 3
A compact three-band equalizer whose encapsulated version as a module enables variable and easy-to-install mounting and provides reliable electrical insulation. Bass, mid and treble can be actively raised and lowered 15 dB with center click potentiometers. The EQ is powered by a 9V battery and can be combined with all passive and active magnetic pickups.
The installation of a Noll electronics course is different from bass to bass, but usually quite easy to do. The included installation instructions help with this. The electronics come completely pre-wired.
We offer Installation service in our German workshop.
