Overview

The FRENZEL JF- B45 SBB "Super Bassman Bluesbreaker" was "INSPIRED" by the Marshall JTM45 Bluesbreaker.and the Fender 5F6A Bassman, but we added a lot of goodies to make it even better. One of the unique features is that it comes with a pair of 6L6's for the Bassman output and a pair of EL34's for the Bluesbreaker output. The 6L6 or EL34 output tubes are automatically switched on when you plug into the F or M input jacks to give you the vintage Fender Bassman or Marshall Bluebreaker tones. The power supply also offers the option of either a tube rectifier for the warm compressed Bassman tones or a solid-state rectifier for the Bluesbreaker dynamic tones. It is truly one of a kind! 


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.   

 

Star ground system to reduce induced current chassis noise.   

 

F and M inputs with separate Gain controls and Bright switches. F Input voiced for the vintage smooth deep warm bass tones of the Fender 5F6A Bassman. M Input voiced for the great Marshall JTM45 Bluesbreaker high mid tones....or you can use an AB-Y switch and create your own distinct tones.   

 

Classic vintage 3-BAND TONE STACK for extended flexibility in shaping your tones!

Tube complement - The amp comes with  (3)12AX7,  (2)6L6. (1)5AR4. 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, KT77’s,KT88's, 6550's, or EL34's in the output stage for different sounds.

I get many compliments on "that Sound"  Keyboard player.  I now can keep up with the guitars when I'm not miked! Love this amp!!! It's great clean or gritty!!  Thanks for a great products Jim!!!!  Bob T. (Massachusetts)


Jim - I heard one of your JF-B45 amps and it sounded amazing!!!  Mark H. (Texas)

Hello Mr. Frenzel: Received the Super Bassman/Bluesbreaker a few hours ago.  Awesome packing job by the way.  I put the tubes in right away and let it warm up.  I have not stopped playing since.  Amazing sounds.  I can’t describe the tones I’m getting out of this.  Its putting my Marshall to shame.  And by the way a Marshall Class 5 Head is an awesome sounding amp.  But this does everything.  So many tones.  And tube options will make the tonal options infinite.  Thank you so much.  I need to get back to work but I can’t stop playing.  Thanks again. Steve E. ( Ontario, Canada) 

Hello: I’m just emailing you again to tell you how much I love this amp.  I’ve had it a couple months now and I can’t stop playing. One week I think the Bassman side is the greatest tone in the world and the next the Bluesbreaker.  Currently I am running KT66’s in it and the tone is unbelievable.  I crank the mids and it is the bluesiest tone ever.  I put a treble boost in front of the bluesbreaker channel and I have instant “Slash” tone.  Amazing.  Thank you so much. Steve E. (Ontario, Canada) 

 Jim - AMAZING AMP!!! GREAT TRANSACTION! - eBay Buyer   auctionsandsuch   7387016279 

Jim - The Super Bassman Bluesbreaker is an amazing sounding amp, and a fantastic pedal platform.  And I know that there's much more I have yet to find in it.  Great design and build quality! Marti K. (Vancouver,BC)
