Hey All,
I've noticed that the ODS-101-HRM Relay wiring is different then the BrownNote ODS and the CierraTone layout shows.
Any idea whys Is there a prefered approach or do they both do the same in the end?
Cheers, Mike

Re: OD Relay Wiring
O.K. - I should have asked this in a little more detail!
I'm looking at the Clean / OD Relay.
The Brown Note D'Lite schematic shows the wiper of the Master Vol connected to the Pre-Amp out. In ODS-101 the wiper is going to the NC position on the relay.
Where did I go wrong?

Re: OD Relay Wiring
The difference is the HRM has master volume's for Clean and ODS where the 70's has a master and a "ratio" that controls the ODS volume with respect to the clean. The relay is wired differently.
Before you get any ideas about changing the non-hrm 70's style relay, the issue is that of loading on the output of the ODS as opposed to the input of the PI. The ODS output wants to see about 100K where the PI needs to see about 1M. The HRM itself provides a load of about 1M through the tone stack.
