The Verzerrer is a distortion pedal from UK maker Fredric Effects that recreates the Bohm Trickverzerrer, which the maker describes as East Germany's only distortion effect. Fredric Effects calls it a highly tweakable recreation that can be considered an exact recreation of the circuit, and builds it with original old stock transistors and diodes, the same components as the original1. It is made in the UK2.
History: the Bohm Trickverzerrer circuit
The pedal's circuit comes from the Bohm Trickverzerrer, a distortion unit made in East Germany. Fredric Effects describes the original as East Germany's only distortion effect, and the Verzerrer as a highly tweakable recreation of it1. Premier Guitar's 2019 press release, speaking for the maker, used the same description when the pedal was announced3.
The Verzerrer was launched in March 2019 as one of three new Fredric Effects pedals, alongside MkII versions of the Utility Perkolator and Dresden Synth Fuzz45.

"A fun box of angry splatter that's a bit one-dimensional"
In the same review, Purvis noted that the Verzerrer and the Regent 150 Preamp are "two British-made pedals [that] have both been designed in tribute to obscure kit from the old Eastern Bloc"2.
