I agree that 8 on the post master is too hot, I've always used 5. Beyond that I dial mine in pretty much the same as all my other C+, III and IVs. Only subtle differences are amp to amp differences in the honkiness of the mids & the presence.
I stopped worrying about tubes when I realized that...
Have you actually compared running the FX send to your power amp vs. running the slave out to it? Power amps are designed to be colorless, and IMO running the FX send to a power amp thereby removing the power section from the tone sounds far inferior. To each their own, though.
That said in...
"bias point 36" doesn't really mean anything in Mesa speak since different tube vendors use different test machines. If you're going to buy non-Mesa tubes and you care enough to do it right (eg. get the bias in a safe acceptable range) you'll want to get your own tester to check bias on your...
In Mark II, III and V Simul amps the Class A pair is biased hotter & you want a 6L6 pair that runs a max of around 45 mA. The easiest way to deal with this is just use mesa RED, or maybe YEL.
For the Mark IVs they were biased colder in general and YEL or maybe GRN is good to go for the Class A...
Most likely that's the speakers. V30s from around 2005 through around 2019 are harsh & fizzy. Find you an older set from 2003 or earlier & prepare to be amazed.
Plus, the 16 ohm speakers in the 2x12s are generally more top endy & cutting than the 8 ohm version which are smoother.
The early one came stock with 440s and the later one came stock with 443s. I did do this test just playing live. however as time went on & I got into reamping & testing using reamps where you can change literally just one thing at a time and close mic record in a controlled setup, I've come to...
I've had both a very early JP2C as well as a recent one with the new iron, though not at the same time. Take it with a grain of salt but I did feel like the new one had better tone. The old one was a little more squished and had pretty bad feedback under high gain.
The old one- (audio quality...
V30s generally aren't ideal for combos. That said, Mark combos generally aren't any good for anything resembling high gain.
Personally I like G12T-75 for Mark IIIs, however in a combo I'd recommend checking out a 75W Creamback (assuming metal is not what you're after). Or, a Black Shadow C90..
Fundamentally the only difference between blue & green is triode vs pentode (respectively) on the Class A section. Guys tend to prefer one vs the other, I've always been a pentode guy.
*Sold* I just converted my 1998 Mark IV wide combo into a head, so I'm looking to rehome the combo shell with the stock 8 ohm Black Shadow MC90 speaker. Comes with the Mesa Trac Loc plates. Condition & everything you'll get as seen in pics. Should fit any Mark II, III or IV wide head with a...
Looks like it was downgraded! hehe Must have been a customer that specifically wanted a not-plus. Well, the parts are there if one could ask Mike to re+ it, however I'm not sure if he's doing mods anymore...
Yes, some Cs had a dot or a stripe above the power cord. I agree, do a loop test & see what preamp board is living in there.
Personally I think the no-EQ 60s are great. If it goes up for sale let me know.
If you're going to test this, IMO the correct way to do it is to first start with recording a reamped a track that you can reamp to each iteration with fixed settings, a separate speaker & mic that's not touched so that the tests are truly ceterus paribus. Otherwise all you're testing is your...
Aah to edit what I said- I missed the "KDRG" part in the title partially because the verbiage called out the PT105, which the Colis do not have.
In the last 6-12 months, Mesa serviced MkIII Colis have been selling in the $3500 range (3 of them that I know about personally), IIB Colis in the...
