The Fulltone CS-OCD-Ge is a limited Custom Shop edition of the Fulltone OCD overdrive pedal, announced in June 2019. Fulltone founder and designer Michael Fuller called it the "ultimate" version of the company's OCD circuit1, and Gearnews described its aim as smooth, creamy and amp-like overdrive tones2.
What sets it apart from the regular OCD is its clipping stage: two MOSFETs plus two germanium diodes12. It ships in a metallic teal finish with a chrome undercoat2.
What it does: an OCD with germanium diodes
The CS-OCD-Ge is an overdrive pedal built on the regular OCD circuit design with a few adjustments2. Its clipping stage pairs two MOSFETs with two germanium diodes12, a combination That Pedal Show also confirmed in its comparison demo of the OCD family5.
Germanium diodes are the reason this pedal exists at all. Fuller said he came across a stash of the right kind and bought all of it25:
"Recently I stumbled across a reasonably large stash of the right kind of Germanium diodes so I ponied-up and bought all"
That supply is finite, which is what makes the CS-OCD-Ge a small Custom Shop run rather than a standard production model2.
How it differs from a regular Fulltone OCD
Fulltone has released several versions of its OCD circuit over the years1, and the CS-OCD-Ge sits alongside them as a Custom Shop variant. The differences come down to three things:
| Regular OCD | CS-OCD-Ge | |
|---|---|---|
| Circuit | OCD design | Same design with a few adjustments2 |
| Clipping | OCD clipping stage | Two MOSFETs plus two germanium diodes12 |
| Finish | Standard enclosure | Metallic teal with chrome undercoat2 |
MusicRadar reported that the changes amount to "a few circuit tweaks" relative to existing OCD designs, harking back to the tone of early OCD versions6. On That Pedal Show, Mick Taylor compared the germanium clipping character against other OCD versions:
"there's almost a softness about the germanium"
That Pedal Show's demo covers the Custom Shop CS-OCD-GE, and there is almost a softness about the germanium version's clipping character5:
History and versions: a limited Custom Shop run
Gearnews broke the news in June 2019, reporting that US pedal maker Fulltone had unveiled what it calls "the ultimate OCD"2. Guitar World covered it the same month, naming Michael Fuller as founder and designer1. At the time of the announcement, Fulltone had not stated a price or a definite release date2.
The CS-OCD-Ge is one of several Custom Shop OCD variants. Others include the Custom Shop OCD v1.4 and the Custom Shop OCD Candy Apple Red, a limited edition finished in Candy Apple Red7.
The CS-OCD-Ge is a limited edition. Its run size is tied to the stash of germanium diodes Fuller bought, so once those are gone, no further units are likely without another supply of the same diodes2.
Price
When announced in June 2019, no price had been set2. Gearnews listed the Custom Shop OCD-GE Overdrive at $231.00 in October 2026, with prices of £212.00 and 247.00 euros also given4.

Questions
How is the CS-OCD-Ge different from a regular Fulltone OCD?
It is built on the regular OCD circuit with a few adjustments, but its clipping stage uses two MOSFETs plus two germanium diodes. Guitar World reported that the circuit tweaks hark back to the tone of early OCD versions. It also comes in a metallic teal finish with a chrome undercoat rather than the standard OCD enclosure.
How much does the Fulltone CS-OCD-Ge cost?
When the pedal was announced in June 2019, Fulltone had not stated a price. Gearnews later listed the Custom Shop OCD-GE Overdrive at $231.00 in October 2026, alongside prices of £212.00 and 247.00 euros.
When is the Fulltone CS-OCD-Ge coming out?
At the time of the June 2019 announcement, Gearnews reported that Fulltone had yet to state a definite release date for the Custom Shop pedal. Gearnews later listed it at $231.00 in October 2026, which suggests it reached the market after the announcement.
Why is the CS-OCD-Ge a limited edition?
Because it depends on a supply of germanium diodes that is hard to replace. Michael Fuller said he stumbled across a reasonably large stash of the right kind of germanium diodes and bought them all, which made the small Custom Shop run possible.
