Now you can add some lovely Big Muff Pi tone action to your favourite circuits.
This drop-in tone stack can be added to pretty much anything you want. Simply locate the best place to add it (it'll differ from circuit to circuit), wire it in and off you go.
You can use it entirely passive, in which case you'll lose a lot of signal level, or utilise the recovery gain stage we've added to bring the level back up as if nothing had happened. The level of this stage is controlled by a set-and-forget trimmer
We've included the facility for a mids control, also a set-and-forget, so you can go for one of the two AMZ presence control circuits. Of course you can wire the mids trimmer as an external pot if you prefer.
Kit includes: PCB, all PCB mounted components, hook-up wire.
PCB size: 22 x 25mm
Knobs required: 1
