Tube power section bad, me emulate it

[Leo Diezel]

I’m skeptical whatever is being designed on will move air and sound as big as tubes do just like a real tube amp. Randall made 400W solid state power amps and they sounded as cold and 1D as you’d expect even using actual OTs.

The only benefit I foresee is smaller footprint and less weight.

Everyone was skeptical and for a good reason, I get that and we knew that.

There's some video with AB test, but you need to play it firsthand to really get it!

 

[Leo Diezel]

Ok thanks for the clarification. In what products is not a full tube, and what replaces it?

So far none, but there are amps out there with cathodyne that only use half tube.
If we are going to make a module based on such amp we will use half tube as well!

Thanks again for that, I'm glad it's been useful! I should probably get back into it, but it's just so time consuming. But the rewards are now rolling in, we made $26 last month alone.

This made me laugh. Casting pearls before swine is unfortunately the only youtube gig out there.

Of course everyone is skeptical, all of the products that purport to simulate this have been complete and utter bullshit in the past Especially the software and amp sims.

I'm curious to try the wampler pedalhead or whatever it's called - i'm glad, at the least, people are trying to make inroads with this.

Sometimes it feels like guitar gear companies are run by people who don't even play guitar. And in many cases, I'm sure my feeling is probably correct.

I disagree. You don’t need to play it although that’s the best way to drive sales. My designs and others can shake cameras no problem with massive pants shaking low end. Either the designs can do the same thing or they fall short like modelers do too. Talk is REALLY cheap in the circuit design business for audio. The more clips and video recordings you can share the better.

Absolutely, but I was talking about the feel, how you share the feel in a video if you're not the one playing? How to you share the punch in the stomach when you are in the same room with a blasting 4*12?

Don't get me wrong, there will be PLENTY of video at release as usual!

So far you can search for Wampler Pedalhead on YouTube, Synergy or Wampler Facebook account, there are quite a lot available!

The only one I’m curious about is the 100W one Friedman is working on, which doesn’t have a clip though right?

Feel is subjective and dominantly a preamp tuned effect - I’ve not found a power amp design change the feel drastically but I have found many NFB loop designs that change amplifier to amplifier that affect the responses of preamp circuits drastically.

There's a Michael Nielsen video of the Friedman, however the design are the same but for the power, so the Pedalhead in Marshall mode is going to be the same.

Pete Thorn is also using it live since yesterday, you may find some video too!

Well NFB/phase inverter is part of the poweramp, so yes that's also what I'm talking about and the whole tech is based on (so to behave like a high impedance source)

Interesting. So you’re emulating tubes with a reactive feedback based circuit but there’s also active solid state amplification as well. I’m excited to see what you’ve come up with and how it responds.

I use a very complex reactive NFB design for my own designs but the preamp is also highly involved as another pole.

Aren't clips of the new Friedman worthless since it's only new feature is emulating "feel"? Maybe I've just never been good about noticing that kind of stuff in YouTube clips.

Kinda excited for it to replace my Boss Waza TAE but absolutely going to wait for some reviews. It's pricy as fuck and I don't need stereo or the BE100 power amp voicing.

 

[S̷͖͑m̵͎͂á̵̺s̸͚̈́h̴̬̑]

The only two amps i could feel the punch in are the clips by @glpg80 and hermansson

 

[S̷͖͑m̵͎͂á̵̺s̸͚̈́h̴̬̑]

But to be honest, i feel like we may be overthinking this whole situation..

 

[stratjacket]

I know the marketing folks have to give us something to get excited about, but it's getting increasingly weird out there. Interested to know if anyone has opinions or comments on these game-changers.

Synergy - we've incorporated an actual “0 watt power amp”, phase inverter and small transformer into the module design. This innovative approach faithfully captures the harmonic complexity and dynamic response of a cranked Marshall poweramp, delivering the rich tone and feel of a full-sized amp.

I’m confused by this. Is this for going direct out (using the DI Out) of the SYN2 or SYN1?
If I’m going out of the SYN2 to a KSR Power amp using the Main outs, does it bypass this 0 watt thing?

No, this zero watt is into the module, specifically JMP, Imperial and Zwreck.

Those amps poweramp saturation is what makes them special, so you want to have this in the module to get that sound!

@stratjacket makes a good point. Was it considered making this power section emulation bypassable?

Seems like for those using the module into an external power amp are getting double dosed - presumably turning down the volume on the dock helps some?

Not by passable and not an emulation, as said it's the real phase inverter!

On a non master volume amp (JMP, Imperial, ZWreck) that phase inverter is 100% part of the tone.

I know. I'm not sure I'm in the more phase inverters = more tone camp.

Anyway I hope to try it someday, just curious about your decision making in the meantime. Thanks.

 

[7704A]

I know. I'm not sure I'm in the more phase inverters = more tone camp.

I think I am, at least for this case, because presumably you're driving the module's phase inverter hard and running the stand-alone power amp's phase inverter clean, so it's similar in spirit to how you'd drive a whole power section hard into a Power Station and then cleanly amplify it with the PS's phase inverter and power tubes.

Exactly! Like on a Plexi, without the phase inverter driving it sounds nothing like a Plexi.
