Here are a few questions about master volumes (not all of which are conventional preamp MVs, so feel free to move this thread elsewhere).
1. According to TUT, the addition of a series 100k resistor between the wiper of a conventional preamp master volume and the PI fixes the low-end roll off. But how does this happen with a series resistor and the series capacitor?
2. In the long list of FAQs on the LP site, it states that the LP-MV automatically keeps the depth of the presence effect proportional to the signal size. Is the LP-MV identical to the bootstrapped MV shown in TUT4 (the one with the dual-ganged pot), or is there an additional circuit to vary the depth of the presence effect?
3. I have yet to try the SL-MV, but I am guessing that it has no effect on the presence control. Is this correct?
