Rump Roast Query

[Vivek_rc]

Hi All
I've just completed a Rump Roast Build (bought in around 2010  but forgot/misplaced it and then it appeared again a month ago in a toolbox!). I do get an output, a misted boost and tone control works, I've built it as a hybrid, switchable between a boost and overdrive. I am not getting a significant boost, it's On a similar level as the clean signal. Also when I bias to 4.5 V I get no sound, I've played with both trimmers and when I set Q1:1.3V and Q2:1.5V I then get an output. Any help and guidance would be greatly
appreciated, thank you -
