Recently acquired a white tolex simul GEQ combo. Swapped in a full set of Mesa tubes, working my way towards that blooming saturated overdrive I hear in my head. But I sure do miss the 'verb like I have on the Lonestar! What are my options? There are a couple different descriptions of the Mike...

I've done fairly well working from the Pass the Sauce factory setting for Channel 2 -- mids are completely off. I'm going for overdrive that's sweet and sustainy but not lacking in bite for my McCarty with57/08s, which I think you could say is in the same ballpark as a LP with traditional Gibbo...

Thanks plan-x. I was considering Mullard 12AX7s from Voodoo ("warm on the top end and lush in the mids with excellent lows. Works well in classic Fender, Marshall & Mesa amps"). Any idea if that would be darker/smoother than the JJ Gold pin ECC83S's? I'm trying to remove some upper mid harshness...

Thanks for the link! Eurotubes' "Mesa Lone Star 6L6GC Gold Pin Oprion (Option)" sure sounds like what I'm looking for: JJ 6L6GC's for power, a JJ 5U4 rectifier, along with two Gold pin ECC83S's for V1 and V2, two standard ECC83S for V3 and V4 along with a balanced Gold pin ECC83S for the phase...

So, my understanding is that Tweed reduces power section headroom by reducing voltage -- does the tube rectifier result in the same effect or something different? It think I hear a greater difference switching from full AC to Tweed than from diodes to tube rectifier. Maybe Tweed effects the...

I'm a newbie to tubes as a life-long bassist, so I'm, you know, somewhat ignorant. I'm quite happy with what I'm getting out of My M1RI, but its going on the bench soon for maintenance/repair, so I thought I'd look into possible mods. A couple searches on the board turned up references to the...

So I just had both my input gains at 8, noodled for a while. Master at 1 1/2 as usual for the living room. Powered back down to 3 and 5 on the inputs. 3 minutes later, poof! No sound, no signal, and smoke rising out of the back of the amp. Two questions: 1) I bought this used from GC (a Mesa...

On #2: I've tried a good reverb and a Full-tone trem through the loop and it seems to muck up all the relative values I've staked out in 6 months of tweaking the gains & stack. A blanket thrown over them is about right. I've thought that maybe you need to crank the loop gain above unity to...

I have the same hum situation on my M1RI -- louder on input 1 also. Funny thing is it just started about a week ago. Also the Uninterruptible Power Supply its plugged into sometimes starts beeping until I go to standby or 60 watts for a few seconds. Then I can go back to 100 watts without the...

Anybody know where Carlos sets the tone controls? I can't make out what they're set to in the pic...

Who is Gil Ayrn and what are his mods? - A curious MK1RI owner

Oh my. Any idea when or where he used a Mark 1?

On the Dumble tip; isn't the Dumble topology broadly similar to the Mark 1? Solid state rectifier, cascading preamp stages, blackface tone stack, 6L6s? Probably with speakers that give up a little sooner...

Holy cow, that's cool. Can you confirm that he played the amp on the albums? It would be great to add some legit punk rock to my Mark 1 playlist. I started a MK1 ampography thread here: http://forum.grailtone.com/viewtopic.php?f=3&t=34904 Feel free to add to it. I'm a happy MK1 reissue (M1RI)...

Requesting per instructions on the settings thread. I'll post what I've got for my M1RI, but its a work in progress. Would love to get some suggestions.
