Compared to the standard OCD v2, the Ge version is described as louder (hence the audio-taper volume pot) with greater definition, wider dynamic range, more sustain and a more tube-like feel. It shares the same HP\/LP switch, Drive\/Volume\/Tone control layout and switchable True-Bypass\/Enhanced Bypass as other Series-4-era OCDs.\u003c\/p\u003e\n\n\u003ch3\u003eWhy guitarists choose the Custom Shop OCD Germanium Overdrive Pedal\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eCustom Shop variant of the OCD using 2 MOSFETs plus 2 Germanium diodes (vs. 1 diode on earliest OCDs)\u003c\/li\u003e\n    \u003cli\u003eMetallic Teal finish with chrome undercoat that shifts hue with light\/angle\u003c\/li\u003e\n    \u003cli\u003eBlue LED indicator\u003c\/li\u003e\n    \u003cli\u003eInternally switchable True-Bypass or 'pop-free' Enhanced Bypass\u003c\/li\u003e\n    \u003cli\u003eAudio-taper volume pot for easier low-range volume setting since this OCD runs louder\u003c\/li\u003e\n    \u003cli\u003eRuns on 9V or up to 18V DC for extra headroom and dynamics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eControls and switches\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDrive knob\u003c\/li\u003e\n  \u003cli\u003eVolume knob\u003c\/li\u003e\n  \u003cli\u003eTone knob\u003c\/li\u003e\n  \u003cli\u003eHP\/LP switch\u003c\/li\u003e\n  \u003cli\u003einternal True-Bypass\/Enhanced Bypass selector switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePower and pedalboard compatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePower: 9 V battery included or 9-18 V DC, standard 2.1mm x 5.5mm barrel plug, center-negative.\u003c\/li\u003e\n  \u003cli\u003eCurrent draw: 8 mA.\u003c\/li\u003e\n  \u003cli\u003eBypass: Switchable True-Bypass or Enhanced Bypass (internal slide switch).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eFulltone Custom Shop OCD Germanium Overdrive Pedal\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eEffect type\u003c\/td\u003e\n\u003ctd\u003eOverdrive\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCircuit \/ topology\u003c\/td\u003e\n\u003ctd\u003e2x MOSFET hard-clipping to Vref plus 2x matched Germanium diodes\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eControls\u003c\/td\u003e\n\u003ctd\u003eDrive knob, Volume knob, Tone knob, HP\/LP switch, internal True-Bypass\/Enhanced Bypass selector switch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBypass\u003c\/td\u003e\n\u003ctd\u003eSwitchable True-Bypass or Enhanced Bypass (internal slide switch)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput impedance\u003c\/td\u003e\n\u003ctd\u003e1 000 000 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput impedance\u003c\/td\u003e\n\u003ctd\u003e10 000 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003e9 V battery included or 9-18 V DC, standard 2.1mm x 5.5mm barrel plug, center-negative\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent draw\u003c\/td\u003e\n\u003ctd\u003e8 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eJacks\u003c\/td\u003e\n\u003ctd\u003e1\/4\" input and output, top\/rear-mounted\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eEnclosure dimensions\u003c\/td\u003e\n\u003ctd\u003e11.5 x 6.0 x 5.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e480 g\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMPN \/ SKU\u003c\/td\u003e\n\u003ctd\u003e676891000902\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eASIN\u003c\/td\u003e\n\u003ctd\u003eB07WM2L6C2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCountry of manufacture\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the OCD-Ge cost more than the standard OCD v2?\u003c\/strong\u003e The OCD-Ge is a Custom Shop build using two matched germanium diodes and MOSFET clipping. The germanium diodes Fulltone considers correct-spec for this circuit are extremely limited in supply, and the pedal is hand-assembled in smaller batches than the standard OCD V2 — both of which push the price above the flagship OCD.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the sonic difference between 1 and 2 Germanium diodes?\u003c\/strong\u003e The OCD-Ge uses two matched germanium diodes (versus one in the standard OCD lineage), which gives it a smoother clipping curve, more sustain and a warmer harmonic character. Fulltone's stash of the correct-spec germanium diodes is limited, which is why the pedal is priced above the standard OCD V2.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does Enhanced Bypass do versus True Bypass?\u003c\/strong\u003e True bypass means the pedal is completely out of the signal path when off. Enhanced Bypass keeps a low-impedance buffer active off-state to preserve top-end when you're running a long cable or many bypassed pedals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it run on 18V and is a special power supply needed?\u003c\/strong\u003e Yes. Fulltone Custom Shop OCD Germanium Overdrive Pedal runs on 9 V or up to 18 V DC. Higher voltage gives more headroom, cleaner dynamics and slightly firmer feel. Use a standard center-negative isolated supply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this pedal a limited\/discontinued run?\u003c\/strong\u003e Yes. The OCD-Ge is a limited Custom Shop build that depends on Fulltone's finite stash of the correct-spec germanium diodes. Once those are used up, this exact circuit will no longer be produced.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHP vs LP switch — which setting for British-voiced tones?\u003c\/strong\u003e HP (High Peak) has a bass-focused, mid-forward voicing that pushes an amp into British-style breakup. LP (Low Peak) is flatter and more transparent, closer to a stacking-style overdrive.\u003c\/p\u003e\n","brand":"Fulltone","offers":[{"title":"Default Title","offer_id":46354366333181,"sku":"676891000902","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/7100\/7485\/files\/fulltone-custom-shop-ocd-germanium-overdrive-pedal-top.jpg?v=1785433286","url":"https:\/\/pedalzoo.com\/en-us\/products\/fulltone-custom-shop-ocd-germanium-overdrive-pedal","provider":"Pedalzoo","version":"1.0","type":"link"}
