mark iic+ & studio preamp

[carloc80]

is studio preamp similar to mark iic+,expecially regarding the lead channel? what are the differences? is the circuit similar?

 

[Aart]

The Studio is based on the the IIC, not on the IIC+.

 

[schnarf]

Both the Quad and Studio are based off the IIC+ and not the IIC. Mike B told me this.

this is an answer from marcus daniel from mesa:

The studio pre and the quad pre are both pretty different in tone from the MK II C+. They still have similar Mark Series characteristics and similar tonal nuances, but they'll never sound exactly like a C+. Neither to my knowledge were built with the C+ in mind.

To me the Studio Pre is in the same tone family as the IIC+ and any discernning ear will pick out the nuances between the two for better or worse but to say they are pretty different I think is a great overstatement. This is the type of comment I would expect someone to make about a Recto vs. a Mark amp but I guess it is all symantics.

anyone has compared studio pre with mark iic+ or another mark series amp?

Studio preamp versus Mark IVA:


Mark IVA: More gain, both new preamptubes so that won't be the cause. The Mark IV was also somewhat fatter and the studio was more raw, more mids.

Poweramp used: Mark IVA poweramp section.

My Studio Pre compared to my Mark IIIC+ is VERY similar in the tone character but I find the Studio Pre to be a bit less uncompressed and articulate with just a tad more gain on tap. The clean on the Studio is one of the most beautiful I have heard and beats the IIIC+.

today i tweaked with the eq of my studio pre and i have obtained a heavy scooped sound very similar (if not identical) to the sound of Master of Puppets and justice for all. i also use a mesa 20/20 and a Hot Plate..
Master...master....

Settings?

I now have my studio paired up with a 50/50. Killer!

I have done a few mods to my Studio pre amp added some caps and resistors and even swapped a couple around as per c+ schematic and also have put the bass shift and deep control on switches as they were on all the time I found great improvement of sound switching out the bass shift as my sound doesn't sound as boomy. I do not own a c+ so I cant compare but the improvement from stock is a world apart IMO

i am actually going to mod my studio pre to c+ specs and i suspected that bass shift cap was there all the time to its not so tight.

where did you add the deep cap? the one before the eq?

 

[JD]

cap 302 15uf removed from ground and joined to a 15k resistor to ground switch goes across 15k resistor and put a .47uf cap across resistor 207 1.5k same as cap 302 originally was.
