Re: The Mark IV thread....!!

When the Mid Gain / Harmonics switch is set to Mid Gain does it make the circuit similar to a IIC++ and III++ ????

Re: Who's the new C+ guru?

It's Randy's company and he does care about forums at all.

That has nothing to do with me.

Re: Who's the new C+ guru?

I've talked with Randy about forums....he doesn't look at them or care about them was the impression I got.
I would not be surprised if he never heard of this forum.

Mesa doesn't own this forum and there is nothing official about it.

Re: Mesa tremoverb combo.

The serial number is close to mine. I haven't had mine open in a decade. Now I'm curious what board is in mine.

I plan on changing out the capacitors on my Mark IV, Heartbreaker and Tremoverb later this year. I'll be looking then.

Re: Mark III power tube break up - doesn't seem possible

I'm not sure if you or most people understand how a tube amp works. Guitar tube amp or any other tube poweramp are running at 100% all the time. What makes them overdrive is how much you put into the poweramp from the preamp. Basically it requires to be very loud to get poweramp overdrive. The mast...

Bypass the preamp and run a hot enough signal into the effects return to overdrive the poweramp.

What's the serial number ?
I think I bought mine in October of 1993.....and over 3000. Production started in June of 1993. My understanding is revision F ended at 2500. Mine has the EIA-606 Schumacher transformer.

Re: Mark III power tube break up - doesn't seem possible

The power amp is always running at 100% output. What makes it overdrive is how much volume you put into it. With a Mark III I get poweramp overdrive with the master at 4 or 5. I'm running the preamp fairly hot also. I'm not going after vintage tones. Which version of Mark III do you have (ie what c...

Re: Triple Rectifier + Tubescreamer + Solo boost = No headroom... Please Help!!!

You can you use turning on and off the effects loop to get different volumes.

You can get as much volume cut or boost as you want with the effects loop method.

Are you using two channels ?
Set the channels similar with two Orange channels.... One set for Rhythm...the other set for Lead.
