Reverb in humble clones

So I'm wondering for those of you out there who have tried to build humble clones, how exactly did you couple in the reverb? (if you did) I am psyching myself up to build one and I was wondering how to mix in the reverb signal. (cause I'm a reverb nut)

Does the 3.3 M resistor and bypass cap (ala AB763) work? can you just take the input to reverb from one side and then couple the wet signal to the other side? The othe rapproach I'm considering is the Chieftan approach where you mix in the wetsginal to the other input of the PI.

Mike D.	Matthew, Wouldn't that be something similar to a Boogie Mark II, sort of? Mike D.

Matthew:

I'm not crazy about what the 3M3/10pF reverb splitter does to a finely-tweaked OD signal so I would vote for the Chieftan approach (although that would eliminate the standard D'Presence control). Here's an idea— why not have a switch to select the signal going to the reverb tank? A nicely distorted signal doesn't really need to be reverberated, but it might be cool to mix in some 'verbed Clean channel with the OD sounds...

BTW there is a neat way of adding Reverb to a 5F6A or Marshall amp over at the Hoffman site. As I recall it uses the second channel for reverb and mixes the two signals through the typical 270k mixer resistors. So the reverb is ahead of the overdrive when you crank up the amp...

Basically , what I want to build (I'll have to practice on some DIY tweeds first) is a BF Twin clean (more accurately a Pro Reverb, since only one pair of power tubes) for clean and a humble ODS clone for dirty. I'm trying to figure out some way to do this without building two complete preamps. I also don't really want to mess around with relay switching.

So this brings me to some sort of bridged channel approach. Maybe the mixing resistors are the way to go and then use a pan pedal to switch channels externally.
