This is the one I have used. What I think would help is a boost on the clean side, I am thinking of the LPB-1, as I have the parts already, but I am not sure where to insert it. Can anyone help?

If I'm reading it correctly (I hope !), the transistor on the right is acting as a buffer for the clean signal, and the pot mixes the clean and effected sound.You could put your booster inbetween the board and the pot.
I'd be wary of using an LBP-1 as they invert the phase of your signal, which won't get on well with the effects loop.
Could you change the circuit slightly to get some variable gain out of the 2nd transistor ?
