Analog Filter Welcome to the Forbidden Planet, an all analog multi-mode filter design influenced by the 1975 Steiner-Parker Synthacon model. Control the Forbidden Planet manually or through CV and take the sound of your Eurorack into new orbits. Forbidden Planet has three filter input jacks: High Pass, Low Pass and Band Pass. The High Pass section is this module’s signature sound—a crisp sharp-cut with no residue, designed to add High Pass filtering capability to Tiptop Audio’s wide range of Eurorack modules. Send a throbbing kick drum through the High Pass section and filter out the the rumbl

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as POST MODULAR LIMITED, number 06889917. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
