Lowballer Twin Envelope question

[Stelloh42]

Hey all - this is not so much a troubleshooting question, as I haven't gotten around to building up my lowballer PCB just yet. I'm trying to understand the circuit schematic of this one and I'm wondering if anyone can explain that following: leg 3 of both the bass & the treble pot, as well as the 3k3 resistor that is on the emitter of Q3 are connected to "ENV" - what does this stand for?
I'll attach a screenshot. Thanks in advance to anyone who can clear this up for me!

And I meant Q1 not Q3

ENV - short for envelope (follower, detector or something similar..). There's a triangular symbol next to ENV - it's a label. All the wires on a schematic that have the same labels are connected. You can use labels instead of running long wires on a schematic. It's a common practice.

Thanks - I ended up staring at this and an original Bassballs schematic as well as a stripboard drawing of an original on the tagboard blog and I was pretty sure that those pot legs and Q1 emitter were all connected. Thanks again for the info!!!
