Re: Is my MKIII Combo overheating?

I played a gig with the amp on the weekend just gone and had no issues at all. I did put a fan in behind it though just in case heat was the issue, but it ran like a dream all night long... Does your combo not have a fan built in? Mine has a hardwired one by the speaker, pointing right at the power...

Re: NAD: IIB "300 Series" Coliseum... As a bass amp?

So does that mean it is safe for a 200W speaker or is that 'bit more' going to be a problem? You have to be more careful with bass rigs, because at low frequencies you can blow speakers without even exceeding their power handling. When I put a 5 string bass through my D-180 into two EVM-15Ls, I cou...

Re: NAD: IIB "300 Series" Coliseum... As a bass amp?

So I am reading this as "I doubt the EVM-15L would last", or "I doubt it would be a problem" ??? Haha, I'm sorry! I meant to say "I doubt a single EVM-15L will last if you're playing bass through it, unless you're consistently keeping it below medium-loud volumes." The couple times I used just a si...

Re: NAD: IIB "300 Series" Coliseum... As a bass amp?

One challenge there is it would be a single 15" EVM-15L taking the full power of the Coliseum. I doubt it, even if it's the higher-wattage version. I had a D-180 (also 180 watts with 6x 6L6 power tubes) and when I ran that through a 1x15 I could see the speaker working pretty hard even before I got...

Re: What do you use your Mark II for.

Only half on-topic, but I use a Studio Preamp in a bass rack rig. Driving a 2:90 simulclass power amp, so I guess adding up to something like a supercharged Coliseum?

Re: EL34s in 2:90 (class A sockets)?

Followup: Mesa tech support says you can do it safely but they don't think it'll sound particularly good because the amp will be running the EL34s colder than they like.

Anyone actually try this, or mod a 2:90 so you can tweak the bias to be more EL34-friendly?

EL34s in 2:90 (class A sockets)?

Has anyone tried running EL34s in the class A sockets of a 2:90 power amp? I was reading that you can supposedly do that, and I can imagine it sounding cool...but I don't have any EL34s on hand and thought I'd ask around before ordering a quad of them.

Re: Mesa Cab Clone VS Studio preamp

The main style i'm using it for is modern rock / punk. As I've only used a rectifier, I'm not sure how the studio would compare as like you say its the mark preamp. Would the recto sound work better for me or is that something the studio could sound good for? I think the Mark 2/Mark 3 family (inclu...

Re: First steps into Studio Pre + 2:90 rig

Played my first show with this (using a pair of 1x15s, because I didn't want to drag a vintage 8x10 to this one). Sounded pretty good, tons of low end for a guitar preamp. At this point I have the outputs on 5, power amp volumes halfway, presences zeroed, and just use the master to set my volume. Th...

Re: First steps into Studio Pre + 2:90 rig

Power amp arrived last night, sounded good at home testing volumes. I still need to make a couple of shorting plugs and bring the whole thing down to the practice space though.

And, of course, re-wire my 8x10 in stereo so I can use both power sections. It never ends.

Re: First steps into Studio Pre + 2:90 rig

The stereo functionality is useful if you're using stereo effects, but otherwise, your guitar is a mono signal, and unless you genuinely need 180 watts, there's not much to gain by using both channels of the amp. No kidding?! I was thinking there must be some obvious solution I was missing since it...

Re: First steps into Studio Pre + 2:90 rig

I also just realized that on a SP or Mark 3 the lead "channel" (i.e. boost and master) comes before the rhythm volume, not after as the tube and knob layout had led me to believe.

Re: First steps into Studio Pre + 2:90 rig

I should point out that I have been using the effects send of my SP in place of the main out for years. I've seen a lot of people say that. How do you connect a 2:90 so that it runs both sides off the same mono signal? This seems like a super obvious thing but there's nothing in the manual and I ca...

Re: First steps into Studio Pre + 2:90 rig

1. Good question. Probably the most convenient thing to do would be to set-and-forget your power amp's levels somewhere louder than what you ever expect to need, then adjust the SP's master volume from there. This was my instinct. What do you do with the SP's "output level" knobs? Glancing at the t...

Re: First steps into Studio Pre + 2:90 rig

Awesome, thanks! I played with it more seriously today in the practice space. The volume/gain thing is so weird compared to the Mark 3s! It kind of seems like: With a Mark 3 if you set the rhythm channel to overdrive, you can hear it start to make the lead channel a bit fuzzy, loose, eventually nois...
