Hi! I would like to use one of my English Muffins as preamp, so i need to make it less distorted. On the product sheet it is recommended to “Substitute Electro-Harmonix 12AU7 for less gain/distortion”. Do i have to change both tubes or just one of them?

The Muff’n already has 12AY7’s which are pretty low gain. If you want it lower the AU7’s will do that!

Here is a guide to tube swapping and gain factors:

You can swap one or both…different combinations will generate different sounds.

Also to make it less distorted turn the gain down! or at least roll back the volume on your guitar!
