The Delta Amp Overdrive is a pedal that replicates the amp-like overdrive tone of the Vertex Steel String Clean Drive. However, it is important to note that Vertex has a history of questionable business practices, including selling rebranded pedals and claiming them to be original designs.

The Steel String pedal was marketed as an original circuit based on research against a real Dumble Steel String amp. However, it was discovered to be a near-exact copy of Jack Orman’s Mini Booster circuit with some modifications. Vertex did not give credit to the original designers and concealed the source of their circuit.

The Delta Amp Overdrive is an adaptation of the Steel String Clean Drive, allowing users to choose between through-hole or surface-mount JFETs. Aion FX offers pre-soldered adapters for SMD J201 JFETs, making it easier for DIY hobbyists to use them as through-hole parts.

In summary, while the Delta Amp Overdrive is based on a well-regarded circuit, it is important to be aware of the questionable practices of Vertex and the lack of originality in their designs.
