reverb idea for an express / liverpool

[zambo]

I dont know if this would work but i had a thought ( danger....DANGER!!!)

ok, could one take a lead from the speaker jack and run it into a series resistor ( unknown value. 100k ish?) and or voltage divider and then into a reverb tank and recovery stage then into the extra triode of an express/liverpool set up as a concertina style phase inverter and then put those signals right into the apropriate power tube grids? The idea being that the reverb would not be as distorted by the stock LTPPI and the signal path is pure all the way to the power tubes still. the dry signal and the reverb signal would mix at the power tube inputs. Does that make sense? Am I drinking the bong water again?

If this is all happening inside one amp with one output tranny, it would be a loop, which is bad. Similar to microphone feedback. You need to tap from a point that is before the point where you re-combine. Or send the speaker-tap signal to a separate amp or set of output tubes/tranny/speaker(s.)

yeah, i guess it would keep reverbing its prior reverb signal. oh well, back to the drawing board. Thanks for replying though

Zambo, are you looking into a foldback reverb concept?

[zambo]

I guess so. I didnt even know they existed. After some study I see this is an old concept with mixed results. I just figure since the express and liverpool seem to only like speaker driven effects etc. tha this is the way to start. It will work with this scenario, the signals just need to be reintroduced out of phase to the power tubes. since the concertina PI doesnt have any gain, their also needs to be a recovery amp. I was reading kevin oconners tut book that discusses this. It will work, I just dont know how well. Now to decide if its worth the hassel.

this just gives an idea of how it sounds. Not going to save the world with it or anything but its better than nothing. http://www.youtube.com/watch?v=wuX5CIzCVVo seems to have left the tone unchanged in the amp
