Yep, that's normal. Same trick with Extreme on the MKV which also drops the negative feedback.

Well, it sounds like that's the one going into Mike for the service & III+ upgrade! If you run it in Class A mode (outer pair only) does it work normally?

I should probably do an update now that I've been reamping, but yeah check this out. To me they have a similar aggression & mid character that I prefer to the mid character of the IIC+ and IIIs. Mark IV 2:46 Mark IIB 3:52 IV preamp w/ IIB power section 4:57

Early IIBs are very much classic rock an a bit loose, however the later IIBs with the RP9C preamp, especially once they're loop modded, are my favorite rhythm amp Mesa made. IMO it has more in common with the IV than with the C+ or the III. My personal Mark hierarchy for rhythm tones looks...

I've had an original Orange Valve tester for years now. It's definitely consumer grade, but it gets me some info without springing for a Maxi Matcher (which I'd rather have aside from the $$) Pros: - You can match sets of power tubes to within ~5% or so. If I'm in a hurry this is close enough...

Finally, a good reason to own a Single Rectifier! You can test 6L6 & EL34 for cheap! :LOL:

First rule I've learned the hard way, if it's not broke don't fix it. All amps that I loved stock, I loved less after they were modded. Blue vs green- the green is actually the one stripe I haven't had, and I'd still like to try one. Personally I'm a pentode guy & don't care for triode (soft &...

The CP1H is fantastic. My favorite III preamp.

There are reasons for this issuance of death. :) The IIB coli power section & the late IIB Colis with the limit knobs are the best there is.

There are aftermarket guys that make this.

I believe what those folks are saying is that after the + mod the circuit is the same regardless of stripe. Of course any native amp-to-amp differences (which can be significant) are still present. That said, I don't know if this is true or not. At any rate, the III+ amps I've had have all, to...

I agree with the first sentence. However, I sort of disagree with the second sentence. With a III, going III+ is always worth it unless you just want the harsh hair metal thing. However, with the exception of the IVb, for the sound I'm going for in my band there is no such thing as a Mark...

Just personal opinion, IMO the no/black stripe is the closest to a IIC+. Starting with red was a significant departure towards hair metal. This iPhone clip I did to my ears tells the story pretty well of what I think are the "closest to C+" amps. Here's a close mic reamp I did including a...

Boss GE10. Old school analog high voltage awesomeness, only pedal to compete with a Mark II/III GEQ.

IMO, with the red stripe I had ++ modded, the ++ took it too far. OTOH, all three of the other IIIs I've had + modded were PERFECT. FWIW...
