Going through the Waza TAE--that is a great box. Waiting on one of those Eventide H90s myself, they look incredible

He's running the Suhr SL68 thru the Boss TAE. There goes his warranty! John does NOT recommend that device.
Same setup and all my SL68 did was blow fuses.

I've been running one with all my amps with no issues--thing works great. R u sure it wasn't an issue with your amp?
I'm pretty sure PT doesn't need a warrantee to get his amp repaired from Suhr haha

We had on RTer destroy his 5K Wizard using one of those. You couldn't pay me to even try one.

That sucks. I'd like to know more about how it destroyed a tube amp. I can only speak for myself, I was just running a KT88 loaded 100w Royal MSG through it and it sounds badass. Done the same with both Friedman SB and TS, a Helios 100 and about a half dozen older Marshalls.
Nothing out there can do what this thing does--it's great in a live situation. As long as my amps don't blow up--I will def report back if that happens!

He is really good with all the effects and processing, I hate his sound.

I forget the exact signs/symptoms but he lost his OT and a portion of the board components. Then it came out that more than 1 amp was going down due to a fault in the TAE. But Boss wouldn't return his calls so no dice on getting any help from them.
Any attenuator is a risky venture with a tube amp; there's always a chance that something fails.

Pete himself has a vid where he discusses the TAE and how it is questionable. I think he mentions the safe bet is to keep those presence and resonance knobs all the way to the left. I'll see if I can dig it up.
Edit - here is Pete quoted on TGP:
"Mr. Suhr has a method to measure impedance curves, I'm not sure how he does it/what equipment he uses but you end up with an accurate graphic representation of the curve. He can do cabs, loads, etc. Was part of the development of the Suhr Reactive Load. MANY loads on the market don't really perform like a speaker cab, m really. Some closer than others. He measured his fav 4-12" and copied that curve identically for the RL. I mean you can lay the graphs on top of one another and they are almost identical.
The results with the TAE were, if you've got the resonance control all the way left, the amp is basically seeing a 20 ohm load down low (resonance), the Boss doesn't make a sharp resonant peak and then fall off like a true speaker curve- it stays high. So then when you continue to move that resonance control to the right, yes you get resonance but the curve just sorta "goes up" below a certain point and never comes back down. So way down low with the knob all the way right- 200 ohms. basically unloaded. Think what a boosted low shelf eq looks like- that's what the impedance curve looks like.
Depending on your amp, you may be fine, or worst case you may have a failure/cook your OT. And I've been told it could be a slow death potentially, like after a few years, hey why's my amp sound like crap.. oh flyback voltages slowly turned my OT to mush.. once again this is amp dependent. Germino says hell no that will fry some of my amps because of the design, the way they run on the hairy edge as it is, as part of the old Marshall sound.
I'm using one on tour so hey I like it but I'm not turning that resonance thing up and risking fuse/tube and or component failure, my SL68 is the first one ever made Proto 01. I wanna keep it functioning and original."

Well Suhr pays him and I believe he also sells a load box? Anyway, he’s using the thing now—as I said, nothing else can do what this thing does.
Luckily I prefer the resonance all the way right so hopefully I’m good

Using the Waza TAE is risky because of how its impedance curve works. Basically instead of emulating a real impedance curve, it just uses a simple bathtub curve which can put too much stress on the output transformer because of the extended sub lows and high highs the WAE does not impede the amp from outputting.
Basically the TAE doesn’t provide the correct kind of impedance curve your amp wants to see. The curve presented to amps drives their output sections harder than they need to be driven. Think of it like letting your car rev it’s engine constantly and immediately without any tires attached to the axles. There's nothing holding the car back from going way too hard and blowing itself up.

Sounds awfully dramatic man. I’ve been using the thing daily for years with multiple amps. And now PT is touring with it. I find it hard to believe it is the ticking time bomb you describe but if I do have issues I’ll be happy to admit I wasn’t careful enough if it helps another rocker out

Per above all the way to the right is outlined as the highest risk.

The TAE has lots of documented design flaws. Lots of horror stories about destroyed OTs.
Quality control issues.
Bad solder joints, etc..

I use a reactive load I built, based on Randall Aiken's paper on the subject.
I run a JCM-800 master vol on 7 for about 3~4 hours a day for many years now.
