Because you own no dirt pedals, the JCM900's Lead channel is pushed to gain 7 to achieve the massive singing sustain originally generated by the Ram's Head Big Muff into a clean Hiwatt. The Marshall's aggressive upper midrange bite and the Telecaster bridge pickup are smoothed out by pulling the amp's treble to 5, presence to 4, and rolling the guitar tone back to 7. Adding a Big Muff clone later will let you switch to the clean channel with low amp gain for the authentic Gilmour fuzz texture.
