The Boogie Board

I've owned both black dot and blue stripe Mark IIIs (both with EQ, the black dot was an HRG, the blue stripe, DRGX). I FAR preferred the blue stripe. When I am back in the market for another Mark III it's a blue stripe long head that I'll be looking for. It was WAY more aggressive and had more gain ...

Look around. They're here. Including photos of the internals of them. You just have to find them.

Oddly enough, I made 1x12 wedge cabinets that were a perfect match for a regular width (not widebody) Mark amp back in the early 80s. And bottoms as well. YEARS before Mesa did. I've made maybe eight to ten of the bottoms, which when compared side by side with a Mesa Thiele enclosure, both with EV s...

An oscilloscope and probes will quickly give you the answers you seek. Since I lack a Mark IIC+ at the present time, I only have half the solution. (The scope.)

No, not to Indonesia. Gibson isn't going to be moving Mesa. As I understand it, that's written into the contract.

Got an RCA tube manual?

Got the Mark IIC+ schematics?

Using the data in the schematics, and the study guides in the back of the RCA tube manual, you can determine the voltage gain of the stages.

Personally I'd like to see Mesa make a single channel preamp or amp that is nothing less than the lead circuit of the Mark IIC+, rendered in exacting detail so that it is the SAME circuit with the SAME component values as that of the original when in the lead mode.

The Rocket 44 kicks ass! Is the one you're looking at the 4x10 version or the 1x12 version? I had the 1x12 version and it's a simple, stripped down two channel amp that has a hell of a tone. Definitely I'd recommend it. I know of only one real flaw with them. One that, if the problem occurs, can be ...

Although I am of course concerned, consider these items: 1: Gibson under the leadership of J.C. Curleigh has made great strides in restoring quality to Gibson's products, and he and the management team seem to be taking quality of their products VERY seriously. But they've been at this for less than...

Eddie didn't use the variac to get distortion out of his superlead. They all get raunchy enough when cranked up. (I'd know, I have three Superleads.) But what does happen is, when you start lowering the line voltage, it does change the tone. Not so much the amount of distortion. Eddie didn't use a d...

As I understand it, a Mark IIB can have an RP11A revision PC board which makes it possible to get it upgraded to C+ specs.

It's only the RP11A board that allows this.

It'll be worth the wait! Congratulations on a bargain of a great amp!

I had one....and I want another one. Of every Mesa I've ever tried, it fits my tastes best. Looking for a very good clean condition used Mark III blue stripe head, DRGX configuration. (Simul-class, reverb, EQ, and I definitely prefer the long head chassis.) Let me know if you've got one you want to ...

Take it to a qualified amp tech. It is probably a mode switching problem.

As long as it's there, see how old the power supply capacitors are. Odds are that they've never been changed, which means THEY'RE DUE. Change them before they fail and take out a transformer.

EVM-12Ls for Mesas (and sometimes good for most any amp) and Celestion Greenbacks and (reissue) Creambacks for anything related to a Marshall for sure. My favorite cab setup is two Greenbacks and two Creambacks in a Marshall 1960A cabinet.
