I didn't think his buffered loop was very good at all. Noisy with tone suckage.
But...
FX loops and pedal boards and signal paths are complicated things...
I think Bogner's loops suck too, so what the hell do I know :LOL:
The Friedman and Metro loops sound the most transparent to me.
The...
Yeah, ideally you want the second output on an amp splitter / switcher to be a transformer isolated out.
Prevents ground loops for sure, but the transformer isolation can also provide a margin of electrical safety when working with vintage amps.
Connect the sketchy old amp to the iso output...
Then you don't want either loop.
The Ceriatone "passive" loop is just an insert loop between the treble pot and Master Vol, and his buffered loop sucks donkey balls.
Order the amp without a loop, and put in a Metro loop after the fact.
And ask Nik not to drill the chassis for the loop, or make...
If you buy a 101b and don't dig the Red channel, look into the "Marvel" mod.
But I would suggest you use .680uf cap // with 10k vs the 1 uf cap for the "Cameron" side.
I found using .680uf cap // 10k gave the Red channel a tonality closer to Blue, but also seemed less congested and compressed...
Yup, I'd replace the tubes, but you'll have to check the bias. Even if it's cathode biased, you should still check where its at.
Also check the screen grid resistors, and replace if defective.
That's fukking great! :rock:
If we ever get live music again, I would love to see him put a bad together and tour. Wonder if he'd play guitar or bass in a touring band?
Edit: just went to the mammoth website, and it looks like he has a band, and performed on Kimmel.
Probably darker and smoother than the newer ones.
Filtering is different too, but that's where the magic is :D
Personally, I think this is the best version, but you HAVE to move the NFB connection from the speaker jack to the 4 ohm tap.
Don't sweat the Synergy vs Mallory cap thing, and the...
Yup, I'm thinking its the speakers as well.
Take the 2 v30's and 2 greenbacks out of the Helios cab and try 'em in the Marshall cabs, and you'll know for sure.
Cool :rock:
I hope you like the change.
Try it out before you put the amp back in the head shell.
If it doesn't work for you, then 2 minutes to put it back and it's all good ?
And make sure you get those channel volumes up and control the amp with the master vol's.
If you move the NFB wire from the 8 ohm tap to the 4 ohm tap, what is physically changing is you are sending LESS negative feedback signal back to the phase inverter. The result is less damping of the PI output ( less compressed ) and more harmonic distortion (perceived as more brightness). This...
Yeah, less compressed and a bit brighter overall.
I should also mention that running the channel vols at noon or higher makes a difference as well.
Try setting channel 3 volume @ 1 o'clock, get your desired output level going with the Master volume, and then go back and balance the other...
These are insanely good sounding mic pre's :rock:
Unless you're willing to pop for a vintage Neve 1073, this is as good as it gets for recording heavy guitars.

Dave Friedman has talked about Variac's and Eddies amp a couple times on Tonetalk.
I could have sworn he said the plate voltage was around 350V when the variac was set to 90V.
In any case, if ya want Variac tone, use a variac. :thumbsup:
TBH, if the SL68 is any indication, I'd just stick with your Variac set-up.
The Voltage selector on the SL68 should have been labeled "Tight" and "Mush"
Just saw this thread.
Holy shit!
Something always seemed a little off with this guy's vids and his amp flipping.
I'm guessing Bi-Polar and he somehow got off his meds and got on a wicked manic run.
If there was no one in his life to intervene and reel him back in, I'm not surprised this went...
The SL68 has a dual voltage secondary and a modified bias circuit with 2 bias trim pots.
I believe the dual secondary switching is done with a 3PDT power switch, with the 3rd pole switching the bias trimmers.
If a quality dual secondary power transformer could be sourced, a similar amp could be...
I could maybe see ch 1 being like the Princeton, and ch 2 like the JCM800.
Ch 3 has way more gain and bottom end than an 800.
Ch 4..... who knows????
The amp may have been designed to deliver 4 distinct tone types, but I doubt Peter actually based any of the channels on any particular amp.
