Tellurion Dynamic Drive

The Tellurion Dynamic Drive is an adaptation of the Fulltone® Full-Drive 1, often abbreviated as the FD1. It was released in 2018 and traced by Aion FX in 2026.^[1]

The original Full-Drive was one of the first hand-made boutique pedals going all the way back to 1995. It was based on the classic Tube Screamer circuit, but with modified clipping diodes and a footswitch that engages a fixed gain boost.

The Full-Drive 1 is not actually a reissue of the original Full-Drive, but instead a new product that is essentially a single-channel FD2 with some tweaks to make it sound more like the late ‘90s units. It leaves off the Boost footswitch, but incorporates the 3-way Mode switch to get two extra settings in addition to the vintage Tube Screamer circuit.

The Tellurion project is an adaptation of the traced Full-Drive 1 with a few additions. The Mode switch is the same as the original, but we’ve added a Clipping switch to select between three different sets of clipping diodes. See build notes in the PDF documentation for options.

Note that while the initial product announcement makes reference to “Enhanced Bypass”, the JFET bypass system first used in the OCD V2, the unit we traced was standard true bypass via a 3PDT switch. The user manual only mentions to true bypass, so it seems there was a last-minute change between the announcement and when it went into production.

1. No tracing journal for this one since it’s almost identical to the FD2. The schematic in the build doc has an added clipping switch not in the original, but everything else is the same as our trace except for standardizing the power filtering with our other projects. ↩
