Thanks for the input guys!
So when I go to order my new set, would it be worth it to get a Matched Pair? Balanced Triodes? High Gain?
Matched sets of tubes really matter only in Power Tubes. It's not really that kind of an issue with preamp tubes. In fact, there are many people here who use different pairs of tubes in their equipment to control the gain structures more to their liking.
Typically, in preamp tubes, it's important to have the mu rating on Triode 1 equal to or less than the mu rating on Triode 2, (Mutual Inductance). The preamp tube will just sound bad if Triode 1 is higher.
This is why many of the members here use different preamp tubes in their gear, they might use a medium gain tube in V1, and a higher gain tube in V2 for a smoother cascading gain structure. On the other hand, They might reverse that for a more abrasive gain structure. It's all subjective to taste. In stock preamps, I like to use strong gain rated tubes because it still produces good clean tones with slight differences in the EQ, (depending on the tubes I use), and still gives me good overdrive/distortion tones. The exception to that is the MP-2 since it has much higher distortion ratings as a stock unit.
Modded MP-1's are an open canvas as far as tube rolling goes. I only have a 3TM which I'm using with my stock MP-1 just to give me the extra gain when I go into a solo. It's a combination that works well for what I need.
