I have a Fender American Zone. The preamp has failed and I want to replace it with one of the Nordstrand 3B preamps. Since the EQ pots on my zone are smaller than normal pots I would like to just use them with the new preamp but I cannot find tech data about pot values on the Nordstrand. Does anyone know if the Nordstrand EQ pots are 100K linear? Also, I am new to this board and cannot figure out how to subscribe to a thread. I assume i can do that so I get email notification of new posts to the thread. Can anyone help me with that? Thanks to all.
