SOUND DESCRIPTION 

 
D50  was  born  from  the  demand  of  our  clients  to  modify  so  many  amps,  until  they 
recognized the unique style and sound in our work. This led us to take almost a year to 
develop this compact 50w all tube amplifier, the very first multi channel amplifier made 
by RedSeven Amplification.  
We are proud to say that this is not a clone of anything. You will not find any ingredients 
from any other builder inside. Like it or not. Here is the sonic features for this amplifier:


 

 

CH1 (CLEAN):

 The clean channel is something between an old ‘50s Fender and 

a late 

ʼ

60s Marshall Plexi. A sparkly and rich clean sound, something that is hard 

to  find  in  modern  multi  channel  amps.  It  can  crunch  with  some  aggressive 
pickups but it stays almost clean with any guitar with the volume set at 4. With a 
classic Strat type guitar it stays clean or an early breakup between 5 and 7, with a 
LP style guitar breakup is little earlier. Tone stack is way more effective than the 
vintage ‘50/

ʼ

60 mono channel amplifiers, you can obtain quite a lot of different 

sounds from this channel. The “Bright” switch also add some flexibility to it, B1 is 
a classic bright, and high shelf around 4KHz, B2 is way more effective and start 
around 1KHz, boosting some nice mids as well.

 

 

 CH2 (VINTAGE/MODERN):

 this channel is where you

ʼ

ll probably want to spend 

most of your time. Gain quantity can be set from a crunchy Marshall-esque sound 
(think  of  early  AC/DC)  to  ‘80s  hard  rock.  Vintage  mode  gives  you  that  sparkly, 
always  focused  and  authentic  crunch  sound.  We

ʼ

d  like  to  call  it  our  today

ʼ

version of the classic ‘70s distorted sound. Modern mode has quite a lot of gain 
and bass frequencies on top, this sound is set for your power chord progression 
and with gain at 10 you can actually start to play some solo parts. “Lead” boost 
adds  another  amplification  stage  by  giving  it  the  right  amount  of  gain  and 
compression to be ready to play solo parts in every moment of the show.
