How It works ? Look here.

Whatever the pickup configuration you plug at the input, the EXchanger will make it transparent

What’s the matter with guitar pickups ?

A pickup tone can be really different from setup to setup. It depends on the pickup itself, of course, but also on the cable (quality and length) and the loads (volume and tone potentiometers) «plugged» into it. Eddy current losses have a massive impact on pickup personality too, especially on low quality pickups. Each of these electronic elements affect the final tone and often change it drastically. Depending how those effects are cumulated, the result can still be satisfying but somehow tasteless with a lot of frequencies missing

The EXchanger corrects those limiting effects on your pickup with all frequencies well combined resulting in harmoniously balanced tones
