So, anyone found out what is this mod is really all about?

About $300

Totally untrue. No offense


Diezels sound the way peter intended them to, if he wanted a more vintage quality they would have them. BUT, if You wanna mod your amp, do it, it's yours and life is short.
 
I LOVE my D-Moll stock. I probably enjoy the compression part too...that being said, having more options is always attractive!

Touché.
 
Just found this thread, seems to contain very valuable info for people thinking of buying a Diezel amp (fantastic amps with German quality).

So to sum things up, the "excessive compression" of Diezel amps some people have been complaining about pertains to amps made 2005 or earlier. It's only these amps that benefit from the Kruse "decompression mod" which involves changing the impedance value of a resistor. This change was already implemented at Diezel's sometime during 2005, this according to Peter himself? That is, on all post 2005 models (VH4, also Herberts?), there is no additional extra compression besides the inherent compression that follows from dialling in higher (preamp) gain in just about any amp, am I right?

Seems this is worth expanding on, especially since this compression thing seem to have been a deterrent for some people in the past.
 
I have no problem with modding an amp, but in this case, I liked the sound of the VH-4 better before the mod.
Mean, evil and more unique before the mod.
I love it!!
 
I wish my stock herbert sounded as good as my dekomped einstein..
 
I'd love a slightly less compressed diezel, but those modded clips sound way worse than the stock clips
the excessive compression was my only complaint about the einstein I had home for a couple months and the vh4s that I played a couple times
I can think of a few really simple mods to adjust those for my tastes, but I definitely wouldn't want them to sound like those clips
suppose the amps weren't readjusted to sound the best for the clips
:aww:
 
The mod sounds and feels better in person than the clips .

The mod sounds great in the clips, but a difference that big makes me pause. Are all the settings exactly the same? Same speakers/cab? mic?
As an outsider who is about to pull the trigger on a Diezel, the mod is very attractive, and sounds great in those clips, but I'd be worried that I made a mistake having it done. The website states that they do this mod on models up to 2016, which contradicts what the inventor has been saying. :confused:

Decisions decisions.....


P.S. sorry for the bump, couldn't help myself.....
 
just leave it stock. There is a YT clip with the compression mod for the herbert, i like it without. Just try your diezel with lower output pickups and let the amps gain do the rest.

Spend your money to homeless children.

So I can email you and you'll send me a VH4 and then I can send the money for the VH4 off to homeless children on your behalf with your blessing? Sounds very generous.

I don't really understand this topic, or why people care what others do with their amps. It got a bit like a catfight in some of the replies. And I wouldn't even bother to reply to an endless back and forth but I wanted to vent something.

I understand why Peter cares, the amp is his baby but for most the other replies.. it's probably either two things. One.. fear. Fear of warranty.. whatever. (I never believe in warranties because if I'm that scared something is going to break, I don't buy it. If it fails.. I don't buy another one in future and buy something else. Even if you get something repaired under warranty, it's a common thing that it can fail again.) Or scared that a mod might actually be useful and you are missing out by not having it or wanting to GAS for it. Fair enough, because we spend enough on gear already, don't we?

I'm not one to talk because I don't have much of that fear. I took apart a brand new amp recently, without even turning it on first. Drilling one hole? You don't want to know how many holes I've drilled in the last 6 months. Converted a combo into a head as well (and if nothing else, it's actually easy to carry to transport now). Most people could at least agree to that.

Same thing with buying a guitar and putting in new pickups before even trying the old ones. Sometimes you know what you want, but something else can be a nice platform for it, with some changes.

The most fun is doing the changes yourself. But I doubt many people in this topic would be doing that, either too scared or too busy riding on bandwagons of something else. Not wanting to change somebody else's idea of perfect.

I really have no comment about the VH4 itself, I've never used it and don't know anything about the mod. As far as I know, the VH4 is a great amp with lots of features, with or without any mods. But everyone has their own idea for tone, something that's individualised.. I don't see anything wrong with that. Sometimes things can be changed that make it unique and personal for you. Whether it's you who does it, or your tech, or the amp company itself. Nothing wrong with custom stuff, as long as you aren't the kind of person to impulsively change your mind on things, because it does hurt resale value. But who are you trying to please.. yourself or the person who will own it after you do? If you are worried about selling it, you're either not sure of what you are looking for in the first place or have already bought the wrong amp. If you own or have shaped something that fits you like a glove, why would you ever sell it?

I'm not saying everybody should mod their amp (or their guitar). I'm saying there shouldn't be any weirdness towards those that do. In any area of life, something that is more personalised is usually going to be more ideal, whether it's your car, food recipes, clothes, your phone or PC, your amp, guitar or whatever else. Other people might not like it, it might not have a big bandwagon of followers and they might not even understand who to use it properly. But they don't have to, as long as you do.
 
I think you misunderstood his post. He meant for you to contact him and he will give you schematics for the mod; do it yourself. Save your money.

Total Vent Fail

no Diezel, no Kruse mods, lots of venting to protect the guitarist who wishes to mod :lol: :LOL:
 
The mod is awesome wether you pay for it or do it yourself. Best part about it is the fact the stock tone is still available. You'll notice the people who've played a modded version love it. It may be a cheap and easy mod, but it's VERY effective.
