Model No. FM-5F6MB

The FRENZEL "Mini Bassman" was "INSPIRED" by one of the greatest Bass - Guitar amps ever built...the Fender 5F6A Bassman. 40 watts of audio dynamite on a small chasiss loaded with features not available in the original Bassman...including a Plexi preamp for the M channel. Smooth warm Fender blues and jazz tones out of the F channel or super soaring dynamic rock leads on the M channel.


FEATURES:

  • Input Jacks isolated from chassis for low noise, eddy currents, and hum.
  • DC on filaments for low 60 hz hum.
  • Star ground system to reduce induced current chassis noise.
  • Type F (Fender) and Type M (Marshall) inputs with separate preamps and Gain controls for the unique smooth Fender 5F6 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 60's JTM45 - Bassman 5F6 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.
  • Classic Type 5F6 Style Presence control for dynamic treble punch!
  • Unique NNFB "Edge" switch on the PRESENCE control that transforms the power amp section into a No-Negative-FeedBack style amp for more open, less compressed tones.
  • Post output transformer LINE OUT with LINE OUT LEVEL control for driving a PA or for recording. Has auto switching internal speaker simulated load if speaker is not plugged in to give you full range tone and loaded output distortion. 
  • Class AB fixed biased 6L6GC's in the output  to give you more power and headroom.The bias is optimized using FRENZEL MVD Bias (Multi-Valve Design)  which allows you to use octal based 6L6, 5881, KT66, KT88, 6550  in the output stage without adjusting the bias.  (Please note you can also use 6V6's but they will only give you about 20 watts output.)

  • Standard IEC three prong plug-in grounded power cord.
  • STANDBY switch to turn off the plate voltage during warm-up.
  • Rock solid point-to-point hand wiring using only the best of parts...low noise tubular polypropylenes caps, metal film resistors, ceramic sockets, switchcraft jacks...etc.

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)


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)


Hi, "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)
