Re: Getting More Bass From Mesa Quad Preamp

Im curious.. are you a guitarist or a bass player? :lol: Just kidding.. Those settings must be shaking the walls! :shock: For me the Pull Deep is only useful at bedroom levels and not at full gigging volume, as the bass frequencies can become heavily exaggerated when volume is increased. I use a hig...

Re: Quad MarkIIC+ mod

I have found some info about the studio c+ mod. http://diy-fever.com/amps/mesa-mark-iic-preamp/ Are you planning to build your own C+?? :lol: It seems you misunderstand what is required here and Im worried your going to end up modding your Quad incorrectly. The Quad doesn't need any major alteratio...

Re: Help me! New tubes for Mesa Quad and placements question

Hey Friedmett,

Just in case its not a tube problem, I would inspect the capacitors for leaks when you have the lid off.


Good Luck!

Re: Quad preamp Ch. 1; = Mk.2C or Mk.2C+, or ???

Howdy, If anyone wants to understand the differences between the Mark series amps/preamps I highly recommend you learn how to read schematics, then all will become clear. Its funny that after 25 years these questions about "which amp is closer to this amp" still come up.. but it will forever remain ...

Re: Studio Preamp advice

Lastly I am thinking about doing the IIc+ mod found here http://www.rig-talk.com/forum/viewtopic ... 3&t=101252 and was wondering if it would be worth a damn since I am not going through a simulclass poweramp. Ive C+ modded my Quad preamp and MKIV and both were tonal improvements in my opinion, the...

Re: Quad pre, TC Electronics G-Force and Rocktron All Access ?'s

Howdy, I highly recommend using the FX send rather than the main outputs.. the difference will shock you! and with the main outputs the louder you turn it up the harsher it becomes. .If you have an early version quad,the output a and b will sound different(due to its ch a and b tone knobs working di...

Re: Studio pre input wiring question, might be missing resistor.

How would you describe the c+mod vs the non modded studio?, Shane you say the non modded is smother, does that mean that the c+mod gives more gain only?. I see that RectoStudioGuy says you've got to keep levels lower, Is it that you get that much more to adjust?, does the bass,mid section also see ...

Re: Studio pre input wiring question, might be missing resistor.

There's a few errors in that Studio Lead circuit diagram from what Ive researched. The 680k should already be a stock part before the 1M pot and the stock 214k is actually a 274k, which is the already the correct value. So both of these do not need to be done. Also the 500pf off the top of pin 6 (co...

Yep... :D And it only takes about 5mins to do it! :twisted:

Although the stock Studio tone is smoother than a C+ so its really just preference. Im planning a custom C+/Studio hybrid tone for my Quad's Lead 1 channel.

Re: Studio pre input wiring question, might be missing resistor.

Howdy Masher, Yes the 1M you found IS the one in the diagram, if your Studio works and sounds fine then all should be well. Although you might wanna inspect the electrolytic capacitors for leakage while you have it open. It's good that your willing to have a look inside and fix it yourself, its real...

Re: Studio pre input wiring question, might be missing resistor.

Masher, Follow the wires from the input to where it meets the pcb and you should find the 1M resistor mounted on the board, off pin 2 on that preamp tube. Resistor color code = brown black black yellow brown = 1M. If someone added another resistor to the input like in that pic, then they did it for ...

Re: Studio Premp w/ MKIIc+ mod

Forgive my ignorance, but does the deep mod and bass shift require a push/pull pot to be installed or is it a permanent "shift"? Hey Caligulus, yea the idea is to make the studio have switchable options so its more like a standard Mark Head. The 170k is indeed incorrect. I forgot to mention that. I...
