Robben Ford Discussion

[phaseinverter]

If the Dumbleator is a bufferd effects loop with a cathode follower which I believe it is, then the loop inside would tap somewhere inside the clean master volume, the return would tap into the phase inverter. This is so the OD section sees the same amount of EFX. Which would explain why he runs the master way up. So in order for the Dumbleator to be a parallell loop it would have to have a mix control which it doesn't. Depending on the gain structure of the dumbleator which I believe does not add gain it could concieveably override the gain of the master volume also effecting the OD gain (trim drive) settings. Very complex set up which is why Robben hired David. Also the bias of the overdrive special is crutial.
