So I just got a MKIIC+ head and have a couple of questions. First, I am trying to figure out what kind of speakers I should use. I am playing it through a Marshall 4X12 with Celestion G12H and the amp dosn't seem to like them too much. I am going to get a 2X12 and play lots of Country and rock. I'm looking for speakers that will give me a smooth, warm, woody tone but will compliment the C+ tone. Would mabey a pair of Jensen C12N or some Weber model be good. The amp seems to like single coils better than humbuckers..does anyone else find that. Next Pre-amp tubes..Right now I have JJ ECC83 in V1 and V4 and a mullard in V3. What may be better choices? One thing I really like about this amp is that even on the lead channel it cleans up very good with the volume knob!! Any help or tone tricks would be very cool!! Thanks- John
