Maxon OD808 Pure True Bypass (P-TBS) Mod

In response to ongoing requests from discerning customers, Maxon Custom Shop is now offering True Bypass (TBS) modifications for the legendary OD808 Overdrive. Developed by former Maxon® Chief Engineer Susumu Tamura (inventor of the Tubescreamer®*), MCS offers two variations of TBS modification to convert the OD808 from its factory-spec FET (electronic) switching format to a hard mechanical-bypass configuration.   For information on our Standard True Bypass Mod, click here. Pure TBS: –The Pure TBS mod removes not only the stock SPDT/DPDT footswitch, but also all of the components related to the FET switching circuit from the OD808 PC board.The removal of these additional components creates a brighter, louder, less compressed tone that is more akin to the Maxon OD-9 in sound than to the stock OD808. The Pure TBS mod uses the same high-quality “mini-3PDT” switch as the Standard TBS mod. This mini-3PDT has a smaller footprint than a standard 3PDT, providing enough room inside the chassis
