FRENZEL  FM-5E3SDX "Super Deluxe" Guitar Amplifier  


The  FM-5E3SDX "Super Deluxe" is the latest version of our dual channel - dual voice "flagship" super amp platform with all the goodies that our customers were asking for...including the Dual Solid-State or Tube Rectifier, Buffered Effects Loop, EL34/6L6 Bias Switch, 4-8-16 ohm output transformer, Presence with NNFB boost, 50 watts of power with a 3 Level Power Switch. Since its introduction, 14 years ago, it has become our best selling amp.

The preamp voices are based on the Fender 5E3 Deluxe and Marshall Plexi which are the same as our Deluxe Plus which has rave reviews from all over the world. Each preamp has its own Input Jack and Gain control which allows you to use an AB-Y switch to select either channel or both to create your own unique tones! The preamps share a low impedance cathode follower which drives a custom three band tone stack  modeled after the vintage 5F6A Fender Bassman tone stack. A Master control sets the level for the phase inverter driver which allows you to set the point of output overdirve. By adjusting the setting of the Gain and Master controls you can generate a wide range of clean and overdrive tones.  Both preamps share the same Presence control which is part of the output circuitry. There is an Edge Boost pull-switch on the Presence control that cuts the negative feedback level to produce a boost in volume and a soaring uncompressed sound for dynamic leads. The combination of all these options generates a wide ranges of tones from Clapton warm to Van Halen hot! 

We changed the output stage design of the original Deluxe from cathode bias to fixed bias to give you a tighter sound and better pick attack...and we replaced  the 6V6's used in the original Deluxe with  6L6GC's to give more headroom and warmth.  For the output trannie we chose a vintage  Marshall 50 watt output for the original classic vintage sound. This trannie provides you with extended low-end warmth and those  incredible enhanced Marshall overtones. All the while, maintaining a perfect balance between the Fender highs, mids, and lows. The trannie  has  4, 8, and 16 ohm output taps which are selectable by a switch on the back of the amp. A three level output power switch was added to provide 1/4 - 1/2 or FULL power. A post output transformer Line Out with Line Out Level control is provided for recording or driving a power amp. The Line Out can be used without a speaker plugged in.  It has an auto switched internal load to simulate a speaker if a speaker is not plugged in. This allows you to produce true Cclean and overdrive distortion tones when recording without a speaker,

For the power supply section we used an oversized custom power transformer which provides great voltage regulation so that you don’t sag too much when you get on it hard. The high-voltage is filtered for very low hum by an equally large choke and 8 filter capacitors. We provde a switch to select between a 5AR4 rectifier  which gives a good compromise on pick attack and compression or a FRED  high voltage solid-state rectifier. 

The amp comes standard with a heavy duty retro vintage steel cage that provides protection and ventilation for the tubes. All the parts in the amp are top-of-the line including polypropylene coupling caps, precision mica tone stack caps, metal film resistors, Alpha pots, Neurik jacks, high voltage Micalex sockets, etc… It has military style tie wrapped cabling for rugged reliability.This is a rock solid point-to-point hand wired amp….a real one of kind collectors item designed to last for generations! 

If you like playing clean you will love this amp…but it will also kick and crunch and sing when you crank it up.  The sound is clean and crisp and develops three distinct types of  crunch and distortion depending on whether you are overdriving the preamp tubes, output tubes, or both.  It will give you the great high mids of the SLP Plexi and the warmth of the Deluxe….plus lot more! Works great with bass, keyboard and harp!


Standard Features:

Normal (Type F) Bright (Type M) inputs with separate preamps and Gain controls for the unique smooth Fender Deluxe warm tones or the Marshall Plexi great high mid-tones....or you can use an AB-Y switch and create your own distinct tones.

Classic Bassman 5F6A style 3-BAND TONE STACK for extended flexibility in shaping your tone.

Master level control so you can crank the GAIN's up and overdrive the preamp without overdriving the output tubes.

Presence control  - used to adjust the high-frequency response and damping factor of the power amp section.

Boost - Unique NNFB "Edge" boost switch on the PRESENCE control that transforms the power amp section into a No-Negative-FeedBack style amp for soaring dynamic leads. 

Effects Loop - pure tube buffered serial effects loop designed to perfectly match the low impedance solid-state pedal levels with high impedance tube levels.

Line Out - post output transformer LINE OUT with LINE OUT LEVEL control for recording or driving a power amp, Auto switched internal load to simulate speaker if speaker is  not plugged in. Inject great tone directly into the PA system with the Speaker Simulated Direct Interface.

Custom heavy duty output transformer for extended low frequency performance with 4 - 8 - 16 ohm outputs selectable by a rotary switch.

EL34/6L6 Bias Selector Switch - Allows you to use either 6L6 or EL34 power output tubes.

Dual Rectifier Mode Switch -  Switch allows you to select 5AR4/GZ34 rectifier for classic Fender sag.or Solid-State rectifiers for Marshall tight no sag tones.  

Standby Switch - Protects tubes from cathode stripping during warm-up.  

Tube Complement: comes standard with 3 - 12AX7, 1 -12AU7, 2 - 6L6, 1 - 5AR4, but you can substitute 12AT7's or 12AU7's in the preamp and driver for different tones and overdrive sounds. You can also substitute 5881's, KT66's, KT88's, 6550's, or EL34's and KT77's when using the EL34/6L6 Bias Selector Switch  in the output stage for different sounds.

Featured Artist - Leon Taylor (Lead Guitarist Taylor's Crossing)

Hey Guys, - Just a note to say the amp wows em everywhere. Tone snobs, even the average listener comments on the great tone. Two sound engineers at live concerts said to me "perfect guitar tone"  I now own two other amps purchased from you after hearing the first one. I just finished building another cabinet/ stack for a friend of mine who bought one. One I bought for the wife is the Purple snake-skin with red Hollowbody- the other is Marshall Red Elephant Tolex...I just bought another FM-5E3SD Super Deluxe-this one off Ebay.(why would somebody get rid of one?) This makes 3 in my studio, 4 on stage as our other guitarist has one. The best tone machine on the planet - I know it is for me, and has made believers out of those in earshot. My original has been flawless on stage and studio since day one over 3 years ago. Thanks for making killer amps affordable. Leon Taylor (Oregon)

Featured Artist - Jim Roberts Video - "Hootchie Cootchie Man" 

I have two Frenzel Tube Amps.. One is a 25 watt 2008 Retro FM-5E3 Deluxe Plus and and the other a 40 watts 2011 FM-5E3 SD Super Deluxe. Jim Frenzel makes the real deal....and at fair prices that all can afford.. I used the 25 watt in the studio exclusively to record our "Devil on a Dirt Road CD." You can hear how I used my Frenzel at or   All the CD songs are there and free to listen to. I couldn't be happier!!! Thanks Jim! — Jim Roberts & The Resonants (California).

"Ultimate Guitar" Review by Robert Roy

Customer Reviews:

Hey Frenzel Team - Proud to say, as of yesterday, I now own an awesome, lightly used, FM-5E3SD  "Super Deluxe with the Quad of 6V6's and the 6SL7 Retro preamp upgrades. It sounds amazing; looking forward to rocking out with this amp for years to come... Ryan D. "RCD Media/The Scarecrow Project Band" (California)

FM-5E3SD  - Jim... I gotta tell you, I have never heard an amp that is better that the FM-5E3SD  you built for me several years ago. It has a three-dimensionality and complexity of sound that I have not heard elsewhere. That head, when paired with my open-backed 2x12 loaded with vintage alnicos, is my desert islander. Robert S. (IL) 

FM-5E3SD - I want to thank Mike Gee Kustoms for the amazing "Rivers Cuomo Strat-o-Master" Guitar and Frenzel Tube Amps for the amazing "Super Deluxe" all tube Guitar amp. Without affordable High quality instrumentation and Equipment like this I would not be where I am today. Dominic Antonelli 

FM-5E3SDR - Hi Jim!! How are you? Just writing to say that I've received the amp today, and I must say it Kills!! Really really sweet, warm, I love both inputs and the reverb also sounds great!! Really, Im very impressed! Its so much better than my expectations :) Thank you so much for the attention and fast shipping. Thank you very much! Regards!! Julia Brandao. (Brazil)

FM-5E3SDR -Thank You very much! This is by far the best amp I have ever owned (perhaps played thru?).My Carvin guitar with DiMarzio super 2’s thru a Keeley compressor, plugged into a Mesa 2/12 cab w/Celestion V30’s gives me all the tone  I need and then some. Again, Thanks.  Brian S. (California)

FM-5E3SD - Hi Jim, I made a combo cab (see 
Pictures page)for my Frenzel Super Deluxe head......I’m pleased with the results and the amp sounds great!! Lots of compliments on how good it sounds (and a few compliments on how good it I borrowed some design ideas from here and there and added some of my own as well. The speaker and amp are separated from each other by 3/4” plywood and there are deflectors that direct the sound coming off the back of the speaker out the side ports.  Glenn T.. (British Columbia, Canada)

FM-5A3SD/6SL7 - Thanks Jim, Got the amp today. Picked it up at the post office, put the tubes in and used it on the gig. Sounds great! I'm really impressed with the fat, but still tight, compression of the 6SL7 tubes. Also the Lineout/powersoak/speak.sim is the best Lineout I've tested. I pulled back all the treble on the PA system and pushed the mid a bit to sound like the speaker I was on (marshall1912... which is dark in character). But then, the feel, which always is the thing that gets lost in the "line out" process, was identical to the speaker feel.   Kudos! Thomas D. (Norway) 

Hi Jim, I just want to drop a note of thanks for the FM-5A3SD amp you built me. It sounds better than I hoped for! My Super Retro Deluxe (6SL7 preamp) is gigging regularly and is a joy! Thanks again, I couldn't be happier! Christian S. (Washington)

Jim, just to let you know,  I am a 53 year old Blues Rocker that has played professionally for 35 years, I have owned, and still own Fenders Marshalls Mesas & Laneys, (just love the toys)  This is the most dynamic colourful amp I have ever used...  Brenton J. (Australia)

Jim, this is an astonishing amplifier. Thanks so much for your great work. Please pass my kudos on to everyone involved WOW.This amplifier is, for lack of a better term, lush and responsive.WOW. Thanks, Gary H. (Louisiana) 

FM-5E3SD - Hi Jim. Sorry it's taken me so long to let you know what I think of my amp. I received it last Tuesday and I wanted to do an unboxing video for YouTube at my friends studio. Well life happens and we weren't able to do it till Sunday. WOW! It's everything I had hoped for, and more.... My friend and I played and played. Thank you for putting out a solid product. I'm sure we will be doing business together again in the future. Bob P.  (Oregon)

Dear Jim and Company - A buddy of mine bought a second-hand FM-5E3SD from another player in our small Canadian town and we both agree that it is the best amp we've ever heard (I'm a young feller but he's been gigging professionally for decades and has owned virtually everything under the sun at one time or another). Finally, I've got to say that you guys are geniuses! I absolutely love the way that you nail the vintage tones of these amps, but build them to a modern standard that allows them to be tweaked almost infinitely Mmy friend was running 2 KT-88s in his and no matter how far to the right we turned the volume, the sound would not break up without a pedal. Truly astounding! The way that you run your business is also a breath of fresh air in these modern times. You don't brag because you don't have to; your work speaks for itself- and speaks loudly for that matter. You offer remarkable quality at prices that put any other manufacturer that I've ever seen to shame (on both fronts).Tone wizards and nice guys? What a combination?!? James M. (Canada)

Hi Jim - Holy yowza!Thank you and thank you again! It is unbelievable tone and craftsmanship. Looks great and sounds even better. The rich harmonics are amazing! And I can't believe the great tones it gets when you push it into overdrive. Simply stunning. You have earned a loyal fan and willing brand preacher and preach the love of Frenzel amps I will. Thank you again. Your newest admirer and fan, Mike D. (Texas)

Jim - When I turned it on... it was like a dream come true! Absolutely georgeus sound! Best amp I've ever had (I had Peavey, Marshall, Laney and many others) and ever played (played almost every amp on the planet)! You are a Tube Wizard! Love the sound, light weight and simplicity. Thank's God I had the opportunity to try your amp and became a believer. I am proud to have it and to use it. Thanks a lot for your help and for your amp. God Bless, Art - From Poland  

Hey Guys, - Just a note to say the amp wows em everywhere. Tone snobs, even the average listener comments on the great tone.

Hey Guys,  -  I just bought another FM-5E3SD Super Deluxe-this one off Ebay.(why would somebody get rid of one?) This makes 3 in my studio, 4 on stage as our other guitarist has one. The best tone machine on the planet - I know it is for me, and has made believers out of those in earshot. My original has been flawless on stage and studio since day one over 3 years ago.

Hi Jim, Love this amp - everyone who plays it is amazed at the touch and tone and all jaws drop at the price. Keep on building! Russ R. (Texas)

FM-5A3RSD/6SL7 - Everything arrived on time and in perfect shape.  Took longer to unpack the box than it did to get a killer Telecaster sound.  You guys done good...thanks!  Ken M.(Texas)

FM-5E3SD/100 - Hey Jim, Gotta say, this is one cool amp! I dig the tones I'm getting from it! I've recently had a few custom amps made that I just wasn't happy with, and then I went back to my trusty Frenzel DP3 that a bought several years ago and I just loved that sound!! My only problem was headroom, but tone was amazing! So I decided on the 100 watt version of the SD! I'll never have to worry about tone and/or headroom EVER!! I love what you do especially for folks like me on a budget. It's definitely great being part of the Frenzel family!!! Jarrett B. (Louisiana)
