With this new version, Catalinbread added a Bias control which gives you a little more gain and body from the stock circuit by simulating out-of-spec parts in the preamp core. They played with the "early" and "later" circuits and found the differences to be a bit too subtle, so they decided to add a..
Voltage control is the basic tenant of modular synthesis: parameters may be modulated by changing control voltages (CVs), simply by plugging in a patch cable. However, during patching it's common to encounter incompatible voltage ranges, with signal outputs and inputs having different amplitudes and..
