I wouldn't think relays in the signal path should be a concern
I agree. Whatever effect on the signal the relays have, and there will always be
someone to argue that they do, it is the least effect that can be managed. i.e. 5fish is using the best methodology available, AFAIK.
It does feel a little tragic to make FF back up and have to remodel this. Are there in-line HPF doohickeys the same way there are in-line attenuators? Just wondering if there's other options for HPF that would keep things simpler and prevent FF having to go back several squares on this design.
One thing for sure... current consumption will go up. New value will probably be between 150mA to 200mA (estimate).
I don't think that's a problem. I really want an Edirol R44, and that burns like 1 whole amp! This is also why I like not having internal batteries for the TS-2, it's actually helpful in that any outboard power solution is likely to be so much better/higher capacity than anything that would fit inside. Bring on the pretty lights, man!
Peace,
