Re: Adding effect loop
I've never added an FX loop to an amp (internally) and am not familiar with the model you mentioned but ... the "basic" idea is to interupt the signal at the input to the power amp. The preamp signal is then routed through the FX and back into the power amp.  
 
There are problems with this (and someone else here could better explain why), like too much signal loss, so it needs to be boosted in some way.  
 
Thats why another tube is usually added.  
I wonder if a clean level boosting device, like the MXR micro amp, could be added as the last FX (?)  
I have never tried it tho. :)  
 
also Stew Mac makes a kit (tube FX loop) I think.
