The perfect musical balance of the amp accentuates the unique characteristics of these wonderful tubes.
No need for matched tubes or rebiasing!

Raising the quality level even higher, the Midnight Special has a transformerless Reverb design with 'True Bypass'.

Tone Quest Report - January 2003

Midnight Special Combo excerpt from the article Under 20 Watts of Whoop-Ass

Chris Siegmund is another visionary whose work transcends the ordinary, and the Midnight Special is no exception.
Rated at 4-15W, the Special is meticulously built using premium capacitors and resistors, including many classic NOS components.
Siegmund also uses octal preamp tubes, along with a vintage NOS rectifier and single output tube.
Features include a transformer less reverb circuit that can be bypassed for extra gain, plus Volume, Mid, Treble and Bass controls, a series FX loop, high and normal power switch, Mercury Magnetics transformer and a Tone Tubby hemp cone speaker.
The Midnight Special is a great midnight-hour amp, but it also passes the test as a terrific small club amp. Its voice is deep, articulate and sophisticated.
The Special wasn't intended to be a high gain amp with intense distortion characteristics, but it excels brilliantly with overdrive pedals, and the reverb bypass does kick an extra level of crystalline gain while beautifully preserving string definition and harmonics.
The combination of P90's and the Special is absolutely orgasmic, and there is a lot of magic to be discovered in this magnificently built amp.

User Feedback:

After 15 years of owning it, I can't tell you how many people I had asking me about that little MS amp when I used to play out more than I do now.
That thing has been put through the paces and I have rarely had to mic it up. I am not sure if the stars aligned when this amp was built but something about it is amazing.

Everywhere I take it people comment on how amazing it sounds and the volume that I am able to get with it. I think I told you before that I played the MS at an outdoor venue one time and didn't have to mic up. It was amazing.
I couldn't imagine changing a thing on it, not even the wear marks on the chrome and covering. Something about that amp just floors me.
I have run it hard over the years in a lot of different situations and it never once failed.
I also played it in an iso box that got pretty hot and cranked it up. It didn't mush out one bit.

It's like I always said, that little MS amp has to be one of the best things out there in the entire world of amp building. I keep tabs on amps and what is around and there isn't much that really excites me.
Everyone seems to use the same designs with minor tweaks to components and values. There does not seem to be too much original thought going on out there.

Believe me. I have tried a lot of different amps and played a lot of different circuits. I had about 30 amps at one point before I started selling stuff off for whatever reason so I have a good base on which to judge things.
Nothing excites me like the Sound King and the MS amps. I have a couple keepers but the Siegmund amps are staying put.

This amp is the most amazing thing I have ever laid my ears on!
Its the gigantic, immersive, 3D ocean of tone! I actual feel like I have found what has been missing all these years as a guitar player.
I have been constantly let down and frustrated because my ear was never satisfied and I knew it wasn't my playing that was bad, it was the amps!

Thanks again,

I've had a LOT of tube amps since my first Ampeg Gemini 1 in 1967.
The Midnight Special has the very best lower volume clean-to-the-edge-of-break up tones of any amp I've ever had.

Wayne Reno

WOW! I'm amazed at how all the controls interact and how an infinite variety of tones can be generated. I have much to learn and experience, but I can't wait.
I'm hearing tonal differences out of my guitar (Myka 104) that cannot be heard on my other amps. I can really dig out all the tonal nuances from the guitar at any setting, and this guitar has a ton of tonal flexibility. Absolutely amazing! Without a doubt the MS is head and shoulders above any amp I have played.

Just wanted to let you know how happy I am with the amp. As much as I knew it was a very special amp when I ordered it, to be able to experience it and experiment with it has revealed much more than I ever expected.
I have never heard these tones from any other guitar amp!! Again -- Thanks so much. I feel very fortunate and blessed to have joined the Siegmund amp community!!

Bruce Basler

I have quite a few amps, but if I could only take one to Heaven it would be the Midnight Special.

Mel Bernhard

Chris, I want to thank you for this wonderful tone machine. While I have had only limited use of it thus far with my stratocaster, I am amazed at the different tonal qualities of the amp, and the warmth and dimension it possesses.
It is only when you compare it to other amps that you really learn of its capabilities. I'm sure as I experiment more with it there will be more surprises that are in store.
I love the reverb and the control one has over it. It is different than my other boutique amps, perhaps more subtle but again you can get the depth you want out of it without it being overbearing or shrill.
I am not a virtuoso on guitar but the better you sound, the better you sound and this amp gets me there, and that is all that really matters.
