Overview

The FRENZEL  "Retro Bassman 100"  was "INSPIRED" by one of the greatest Bass / Guitar amps ever built...the Fender 5F6A Bassman....but it is not a clone, It has more power ...and  other unique features.  You can play bass that will rattle the windows on the Normal channel...or super soaring leads on the  Marshall Plexi Bright channel.


Standard Features

Input Jacks isolated from chassis for low noise, eddy currents, and hum.

DC on preamp and driver filaments for low noise and hum.

Normal and  Bright inputs with separate Gains

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

Classic Type Bassman Presence control 

Unique NNFB "Edge Boost" switch on the PRESENCE control that transforms the power amp section into a No-Negative-FeedBack style amp for more open, less compressed tones.

 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 Microphone Simulated Direct Interface. 


Class AB fixed biased  Quad of 6L6GC's in the output for more power,  fantastic  headroom....and  smooth blues saturation sounds.

Reviews


Hi Jim, There were not a lot of reviews on the Retro Bassman 100 when I purchased it, so I wanted to share my experience. I have been using the Retro Bassman 100 for bass and guitar, and the tone has an incredible 3D quality.  As you might remember, while I was waiting for the RB-100,  I ended up purchasing a Eden 1200 bass amp because of a gig I had to do. The Eden 1200 (Minnesota made version) is at the high end of performing bass amps.  

When it comes to comparing the two I find them to be equal in sound abilities, in their own ways.  The Retro Bassman 100 with the tube rectifier gives a rounded sound that is very articulate in how it represents effects.  The Eden (which has a 2 tube preamp) can't even come close to giving the same tonal quality, in any way shape or form.  On the other hand the Eden has a punch the Bassman can't come close to, even with the solid state rectifier. 

The Eden 1200 is an 800 watt amp in stereo mode and 1000 watts in mono mode at $2400.  The Retro Bassman 100 is a 100 watts at $1400 with all the bells and whistles.  Both amps push both my bass cabs at the same time (Bergantino HD112 and a Bag End 112) equally well.  The bottom line is that between these two amp there is no tone I can not get, where for the price, the point to point and no circuit board construction the Retro Bassman 100 has been a far superior purchase.  There are no words I can use which can describe the varied tones I get out of this amp.

Then, there is using the Retro Bassman 100 as a guitar amp.  There is only one word that comes to mind, WOW.  All of the qualities which hold true for bass use go true guitar use.  

What I like most about it is that I get incredible feedback at any volume level.  Compared to Mesa Boogie, Fender and Orange guitar amps I have owned, the tonal qualities of the Retro Bassman 100 at lower volumes can't be beat, where the amp can still push really high volume levels.  It is like getting into a high performance car that drives really really fast on very curvy roads, compared to one that can only be driven fast in straight line.  

I am using a number of different effect units including the Zoom B3 and G3 multi stomp effect units, Line 6 Pod XT live, Sans Amp Tri-AC , Digitech Valve FX, among other dedicated effect units.  They all sound incredible through the amp.  Next I am setting up my iPad with Radial Reamp, an Apogee One, and Jam Up Pro, Ampkit, and Bias apps to see how they perform with the amp in live use.

All of my guitars electronic systems are customized to the max.  All copper shielded, elaborate ground systems with grounds going from the input jack to everything (including hard soldered to the pickups), and quality pots, caps and wire.  I do this to allow the pickups to hear better.   A guitar or bass setup this way allows a quality amp abilities to really shine, and the Retro Bassman 100 really takes it to the next level.  I have used other boutique amps that can perform equally at the guitar level, but not at the bass and guitar level and definitely not at the price.  Very happy with your product.   - Rick K.
