Retro Micro-Head...............$495.00


The FRENZEL  "Little Jessie" uses the same Fender/Marshall circuit that we use in our FM-DP1 Dual Pro One preamp which has rave reviews from around the world. The power amp uses a Class A single-ended cathode-biased EL84 with a Pentode - Triode mode switch for either 5 watts or 2 watts output which allows you to produce smooth warm blues tones or rockin' overdrive tones at low volumes. Perfect for late night practice sessions at home and small venues or you can use the post output transformer Line Out jack to drive higher power solid-state or tube amps or PA's for larger venues! Little in size....huge in tone! You will be amazed at the tones this amp will produce!

I have a Heritage 335 whose sound I had never been 100% happy with. I think that What was lacking was the perfect "amp partner." For reasons I cannot explain, Lil Jess and the Heritage sound just about perfect together. Bottom line: I am doubly happy, now that my Heritage has met its match.  Robert S. (Illinois) 

Hello Frenzel, Just a note to say how happy I am with the Little Jesse. It has a lot of character. Very nice job on the amp & it does just what your company said it would.  I am still overwhelmed by the sounds that come out of this amp. Doug T.(New York)

Dear Jim - The amp arrived fine (two weeks a go) but i was not able to test it until yesterday…I am very happy! It is a great machine! I plugged to a Marshall 4 cone cabinet as amp (not as a preamp) and it is really great! Mostly, I used the M channel, but this is the sound I was looking for!...I don't need any pedal anymore!  Thanks and it has been a pleasure to make business with you! Roger M. (Hong Kong)

I received the amp and it is absolutely wonderful. PBass, acoustic with pickups, and Les Paul! Plenty of volume, various tones for each of the guitars and great as a preamp to my big tube amp. It is light and portable and going to Thailand with me soon. Quite sweet. Thank you! Axel B. (Colorado)

Greetings to Frenzel Amps!!I just wanted to send some feedback on my Little Jessie order.  After a short delay I was finally able to sit down with this amp and put it through some tests.  I also had a chance to perform with it last week and I am extremely happy with the Little Jessie!! After testing the amp out with a Gibson Les Paul and custom Telecaster, I can say this is one of the finest most toneful amps I've ever owned.  All options functioned perfectly, the pentode/triode switch and line outputs and custom preamp voices I requested give me a very wide range of tones out of a single device.  The treble & bass boost on the tone stack really add to this versatility.  The F input is warm and deep with a great overdrive, giving me some great jazz & blues tones.  The M input is outstanding - bright and punchy, with a more aggressive crunch, very much the tone of early 80's punk and metal.  I have tried this amp with all manner of pedals, and in every test I was able to get a huge range of excellent recognizable tones with very little noise and a stunning 3-dimensional presence.  The amp was everything that was promised and so much more, a real awesome addition to my studio that will be my main amp from now on - at least until I can buy a higher wattage Frenzel!! Thanks very much for all your work.  This amp is fantastic and I am very happy!!   Carlos G. (New Jersey)
