A modern classic, there has been various different incarnations of the OCD. These captures are of the V2 which, amongst other tweaks, features a new Class A configured discrete 2N5457 JFET input section that, according to Fulltone, results in a‘raising the input impedance to 1 mega ohms (previously 330K) and increasing the dynamics…resulting in significantly better interaction with both single coil and humbuckers.’
