Diezel Schmidt

As of today, I'm a new Schmidt owner! I sold my Einstein for it. Its serial number is 005/105 and to my surprise it has the centered nameplate.

I have only been able to play the Schmidt for approx. 1 1/2 hours and only in my bedroom through my Framus 2x12 cab. I have a Diezel RL 2x12 at the rehearsal space. I tried out two of my guitars, some pedals, guitar/cable only and played around with all channels, the loop and the reverb. However, there are few peculiarities I've noticed, and I'm not sure whether they are conditioned by the construction or may indicate possible faults (i.e. with tubes).

On Channel 1 when I completely turn down the volume knob, I can still clearly hear an amplified signal when I play with the guitar. It's not loud but it's definitely audible. This phenomenon is neither present on Channel 2 nor Channel 3.

I also noticed that the clean channel is audibly noisier than the the drive channels, regardless of whether a cable/guitar is connected (in which case the low-level hum and noise is louder) or not. It is nothing dramatic but clearly noticeable.

I didn't experience any of the above with the Einstein, which was equally quiet on all channels.


The next points are more like questions since the Einstein didn't have these features:

When engaging the loop, is it normal to have a slight volume drop which also sounds like the highs and lows are cut off a bit? This happens irrespective of how many and which pedals are in the loop, or if the loop has no pedals at all in it and is shortcut via a patch cable. This is using 100% wet. I haven't played around with the parallel side of things.

When engaging loop or reverb, there's a noticeable and audible lag while playing. Is this normal for this kind of amp design?

The Schmidt seems to get very hot at the back. More so than the Einstein ever did. When I unplugged the loop cables, the metal part of them (with the tip) was surprisingly hot.


Some of what I have described may be due to the Class A construction. I'm really not an expert and would be happy to be enlightened. I only wish to understand if the amp is functioning as it should be!

Uhhh.... Sounds weird!
Bump for a reply.

Bump indeed. I'm less than happy at the moment due to these unresolved questions. :( Just to be clear on this, since I haven't mentioned it before: This concerns the operation only. Regarding sound, anything I've heard so far has been PHENOMENAL! This is why I'm even more anxious to learn whether there are faulty parts or not.

Today I gave the amp another round of testing. Same results. I'm thinking that it may be one or more faulty (microphonic) tube(s). Would this also explain the fact that I still have sound on Channel 1 with the volume completely down? This channel also still has more background noise than the other two.

I'm also curious to learn if the lag when loop or reverb are engaged is normal for this amp (or this kind of amp design). There are songs in which I engage or disengage effects while playing. On the Schmidt, I get a lag and an audible "blop". This may be less than dramatic in live settings, if I manage to hit the switch during a loud passage or a drum kick but when recording live takes, changing anything on the amp would be impossible. I'm also still hearing a slight volume drop and/or a perceived change in sound (less highs). Again, nothing dramatic but noticeable to my ears.

Coming from the Einstein, I'm used to dead quiet operation on all channels and in the loop. The amp was bought new, by the way, so I can always benefit from the 30 days return policy. But what I've heard of it so far, has me lusting after its tone so much that it would be hard letting it go again (at least for some time).
 
You should email Peter. I'm sure that's what he'll ask you to do when he sees this thread.

I can gauantee you'll get an answer.

I need an email to peterdiezel (at) diezelamplification (dot) com
I think most of the problems can be solved.

Thanks,

Peter
 
Peter is Class A in customer support.... :thumbsup:
Keep rockin' guys, :rock:

Any chance of perhaps sharing the solutions peter may suggest to your problems? I've noticed my loop cables get quite hot and also noticed the aforementioned slight background noise on ch1 and super small tone change when the loop is engaged even with nothing plugged into the loop.

Still, couldn't be more satisfied with that amp. I second it's pedal taking ability; I've only tried a Zvex fuzz factory into it thus far but I've had AMAZING results!
 
Since the chassis is mounted reverse in the housing
get a bit hot from the hot tubes. No problem at all,
we use good components so please no concerns.
