Hi
1 The Orange Drops are OD 6ps/225P. Read earlier in this post plz (no idea about this, just trusted my ears)

2/3 I run everything in series, OTS-->Rollator-->Dynacord --->Rocktron-->Rollator-->OTS (the whole signal goes though the Rollator)
But!
The Dynacord is moddified and is now true bypass
The Rochtron (only used for Reverb, Delay, Tremelo and Chorus) has an internal mixer. The dry signal stays analog and you mix in the (digital) effect. So only the wet singnal goes through an A/D converter. I feel this is very important. In a sense the Rocktron is almost parralel

I would have preferd Verdumulator myself, but this was Erwins choise

You're welcome
LOL that's all beyond me. Luckily Erwin knows what he's talking about. We just did some A/B/C testing and agreed the OD sounded best. I think if you listen to the clips it gives a pretty good idea.
