Howdy Y'all. Upon cleaning the in and outs of my 3210s and my 3315, I can't help but wonder how much ( if any) of the tone in these amps relies on these old Drakes. I must add that all my models (3210s) do tonally have a little bit of different feel in each one - a few a little bit tighter, a few feeling a little bit of a sag. I always find it interesting in these models. Anyhow, for you pros out here, what's the consensus on this? Thank you in advance.
