I'm considering adding the extra OT impedance switch to connect the brown-white transformer wire. The Tramp layout diagram shows the centre pole connecting to V2 pin 8. I have the feeling that this should be pin 3, not pin 8. Can anyone clarify?
Thanks, Iain

Hi Iain,

You are right. The center lug of the switch should go to V2 pin 3. It's shown correctly on the schematic.

Thanks Mitch

After scanning the builder's guide again I found a reference in the Tone Tweaking section. It also correctly shows the switch connected to V2 pin 3.
