It's almost 2025, who's using Diezel?

It was on Facebook.

It was just a NFB mod. I added a pot in one of the 4 ohm speaker jack holes.

I’ve never heard such a drastic difference in an amp than adding that NFB pot to a Diezel. I’ve done it on a Hagen and Herbert also. They open up and come alive. Easiest and best mod for them. Easily reversible with no drilling.

Wish I could see / hear that...This is interesting.

like this? (saw it on facebook)

Just add a 250 k pot in series with the NFB resistor between NFB resistor and depth cap and or the tap.
 
I have had a love/hate relationship with the Diezel stuff over the years. They have a very unique tonal signature and feel. Unique enough I often miss it when I don't have a Diezel, but when I have had one, they have never been my "go to" amp.

If I were grabbing one today, it would be a new VH4. All 4 channels on those new VH4's are great, so you end up with a pretty versatile rig.

This post also makes me reminisce about the early 00's when these were rare over in N.America and there was huge hype surrounding them. A Harmony Central post would read something like,"Just got my new VH4....absolutely destroys my 2 channel Triple Rec, Mark iii and Pittbull!" Funny how things change in guitar land....

What is "bounce" and "sag"?

Hard to explain in words, as it’s a feel as much as a sound. An amp expert could probably explain what’s happening in a technical sense, but the best non-technical description I’ve seen was that notes compress (sag) for a split second when you hit them before releasing. It creates a sense of “bounce”. Useless explanation, but the best I can do right now….

This is how I think of it:

Sag is an attribute of a tube power amp unable to deliver power / respond to a sudden increase in current draw when you hit the guitar, causing a sudden drop in the power supply voltage. So you hear a brief drop in volume and as the power amp recovers the notes sound like they're getting louder (bloom). The drop (sag) and the recovery (bloom) amount and duration combined are "bounce".

Some digital modelers let you control the sag. Some modern amps have overbuilt power supplies so they exhibit little or no sag; I'm sure some amps provide a way to adjust the sag too?

high sag makes an amp feel soft, or spongy, more open, as the power section can't keep up with demand; vs low or no sag where a power section can keep up with demand feels stiff or less dynamic, more compressed.
 
If this is how a NFB is done! Man this needs to be mandatory!!!

Btw mine is a 2005 with motherboard of a 2024. It slays!

If a proper Blueface reissue happened, or an original Blueface under 10k, I’d be all over it. After about 2 seconds of playing @braintheory ’s Blueface, I knew I wanted one
 
I love Diezel. I have the Hagen and will never let it go. I had a Hagen for about 10 years, sold it and instantly regretted. Bought another one earlier this year and it’s a keeper. I also have the 4x12 FL Diezel cab, but rarely use that these days.

I also had a Herbert for a while but prefer the Hagen.

vh4's always have a processed kind of thing going on i never really dug, ive heard herbert and einstein clips that sound good but not enough for me to want to pull the trigger on one without trying first

My vh4 sounds very unprocessed
Like a sledgehammer . Most Diezel clips I’ve heard don’t sound like my diezels

I have heard Diezels described as "processed" as well on a number of occasions. I think this commentary may be semantic to some degree. Having owned a VH4, D-Moll, Hagen and Herbert...None sounded like what I would described as processed, but in my opinion they do sound somewhat "produced". Almost like some studio magic in post had already been applied. This is particularly true of the Herbert in my experience. George Lynch once recorded some tracks with Bob Kulick (RIP) in Van Nuys using my Herbert MK I and Bob told me that neither he or George could believe how little had to be done to make the basic rhythm tracks to sound "perfect" in the mix. That said, Diezels certainly do not present as "raw" sounding the way most would describe a vintage Marshall, but also not cold or digital feeling the way most ENGL amps have sounded to my ears. Not certain if this makes sense.
 
Oh forgot, I do have the Diezel VH4 and Herbert Synergy modules as well as the Hagen amp, but not sure if that is the spirit of the OP question though.

My Herbert is a keeper. Dug it hard the first time I plugged into it. Much like the Ultralead, it makes me grin every time. I have the perfect speaker setups for that amp...for me anyway.

I can make any Diezel raw af . Noise gate,boost. Mid gain on the amp
 
Thanks for the ideas, thoughts and input.


Found a good deal on a mint VHX.

Looks like it covers the range of Diezels, jack-of-all-Diezels, master of none...with direct out, effects, IRs and more; my guess is it will sound "processed" or "produced" compared to the other Diezels.

It's the JVM410H of Diezel, but I like my JVM so...
