So about the EH Q-tron

[WimWalther]

I had one of the original (stainless case, wood box) EH QTron pedals back in the 90s. I'd like to get another but just don't know what to make of today's offerings..

How do the various new models (Q, Q+, Micro, Nano, etc) compare to the unit I once had? Are they any much good?

Also I noticed that one model, maybe the Micro, has a "Q" control that doesn't exist on the older or current full-size models. Is this the same as the "PEAK" control on others?

Thanks, I'd appreciate it if you could fill me in on these details.
