FM-5F6MB - Jim and Team Frenzel, et al...Privileged to own three of your guitar amps. Started with a Deluxe Plus
Vibe...I picked up on ebay...using KT66's  du Tung Sol.  Best amp I've heard.  I've built amps, fixed amps and modded amps since the 60's.  Got pretty much THE amps. My vote is to award JIM the Western Electric Emeritus. I now have his Mini Bassman (which I dig in the Jim Marshall mode) and another Frenzel Deluxe Plus Vibe (which I dig in the F mode)...all with KT66's...Genalex and Tung Sol.  I play with a cord. A wood tele and two 12" Marshalls,  stacked.  Weber Alnico and Jensen Ceramic. JF, From one old radio guy to another...hey, good job.   yo ron  - Ron J. (Oklahoma)


I received my Mini Bassman last week and I am thrilled with it!  It sounds wonderful with guitar and Rhodes through 2 JBL D120Fs.  Such a natural transition from clean to overdrive, rich, shimmery sparkly tone with great clarity, just what I've been dreaming of.  It sounds so pure with bass through a 15" cab.  Even with 6v6s in it I get a stout sound.  It's everything I hoped it would be and I can't wait to hear it in the mix on stage! Thanks, you guys did great work with this one. Kenny H. (California)  

Dear Frenzel Amplification, I received the Mini Bassman Very well packed and built like a tank. After trying different combinations of tubes I found the three 12AX7 tubes, two 6L6GC power tubes and a 5U4 rectifier tube for a little more sag. The 5F6A Bassman input sounds excellent, the Marshall Plexi input sounds excellent also. When I use an AB switch to combine the inputs I discovered Tube Amp Nirvana, absolutely stellar tone to my ear. I added the Attenuator switch which comes in very handy. At the full 40 watts, this little amp is really loud. I am playing the amp through a close 2X12 enclosure with 2 Celestion Vintage 30 (16 ohm) speakers in Parallel. The amp sound great with Semi-Hollow guitars, Fender Strats, Gibson SG, Fender Telecasters. Single coils, humbuckers, P90s, Seymour Duncan rails. The amp responds very well to all types of pedals. If you are looking for a compact head, with a lot of versatility, look no further. Thanks Frenzel - Joe V.  (Ohio)

Hey Frenzel Team - Purchased a FM-5F6MB Mini-Bassman about 4 months ago. Since then I've gigged indoors and outdoors - sounds great with my 1x12 cab, LesPaul, drive pedal and touch of delay. Clean on F-channel with bright-pull engaged was pure&smooth at the blues festival yesterday. An outdoor venue - set master at 3/4, gain at 10:00, bass down & presence up - exactly what I was looking for. Surprisingly loud, fit in the mix with full 'Fendr' tone + sparkle. My thanks to Jim and the Frenzel crew - this light-weight amp is affordable quality. Robert O. (Oregon)

FM-5F6MB  - Played my first gig with the 5F6MB last night, blues&rock - what an improvement over my last amp! Sent it thru a 112 Weber spkr, I use 2 pedals:  EH echo + overdrive. Using a single-coil guitar (strat), F input is the place - Using my Les Paul, it's a mix of F and M. The M circuit removes some of the bass frequencies that come with humbucker PU's + bassman circuit, reducing the 'boomy-factor.' Tone is still there, I like the balance by setting them half & half F&M - sounds great. - Regarding  tubes in V1 preamp position...12AU7/ECC82 delivers less clip at high gain/master settings, good for jazz or anything clean - 12AT7/ECC81 or 12AX7 delivers more clip, better for blues/rock. - Seems like the 12AT7 is just right for me, at this point.  Robert O. (Oregon)

FM-5F6MB This is a fantastic little amp, really special and incredibly versatile, just wanted to let you know.  I think I'm going to build a bracket for it to mount to the fliptop, by the way.  Thanks so much!  Best, Kevin B. (New Jersey) 

FM-5F6MB  - Man, this thing is AMAZING!   Does everything I want it to, and then some.  The low end response is amazing.  Completely Satisfied, and looking forward to taking it out on gigs.  Amazing work, folks!   Amazing!  Best, Brad R. (California)

Hi Jim, "Just a little plug for Jim and the fine folks at Frenzel. My experience with them and the Frenzel Mini Bassman has been great. Out of the box it was a little too hot for pedal steel, but all I had to do was some tube swapping (a 12AT7 in V1, and a Weber Copper Top solid state rectifier) to make a great clean tube machine for pedal steel. It's got a lot of tone-tweaking features, 2 channels with different voicings, and with the way the tone stack works I can even shift the curve to put the mid scoop where it needs to be. I could not justify one of the high-end boutique amps, but this will keep me smiling for a long time!" (Built the head cabinet myself, don't blame that on the Frenzel folks!) Tommy B. (Virginia)
 
You guys did good!! - The Mini-bassman arrived yesterday in excellent condition while I was at worship practice.  I built the cab for it over a month ago and was able to install the amp today and it sounds great!  This is my fourth Frenzel and never a disappointment with any of them. Many thanks, John W.(Indiana)
