MosValve™ Real Tube Combo Amp 

Congratulations on purchasing the most innovative, unique and best performing combo amp in existence.   With 
world-renowned and patented MosValve circuitry for power coupled with a "new design" 4-stage TUBE front-end 
preamp, your new combo is truly a major advance in the art of guitar sound production.  
 
Please take some time to fully familiarize yourself with the many design features of this amp. It far exceeds the 
limits of comparably-priced conventional equipment.  
 

 

•

4-Stage TUBE preamp section. Tubes are individually hand and ear-checked for low microphonics and hum.  
We reject over 50% of the tubes we receive from our suppliers.      

 

•

DC filament operation of preamp tubes to eliminate the common tube hum caused by conventional (and 
cheaper) AC designs.    

   

•

Lower plate voltages insure greatly extended tube life. BK Butler is the pioneer of low-voltage designs for 
vacuum tubes. Tubes typically will not have to be replaced for 2-3 years under normal conditions.      

 

•

Continuous anti-feedback circuitry eliminates over 60% of the typical “squeal" or HF screech apparent in 
many amps. This allows higher volume levels at closer proximity to the cabinet, as well as a much "fatter" 
sound in close quarters.  

 

•

Two channel operation plus a foot-switchable "stack" function in Channel 1 gives versatility of 3 channels. 

 

•

Separate EQ sections for each channel. Channel 1 features a radically expanded range for overdrive incor-
porating true active response with passive musical tonality.  

 

•

MosValve power section. Identical to a single channel of our famous "RT-962" rack-mount MosValve power 
amplifier.  Since its introduction MosValve has become the new standard of musicality by which all other 
amps beg to be judged.  

 

•

MosValve powered full-sized Accutronics®  spring reverb system actually driven by a separate onboard 15 
watt MosValve power amp.  This reverb system is the closest thing to the classic Fender™ style reverbs 
from the past and utilizes the same specs and reverb tank.  

 

•

Special British-coned, USA assembled speakers or optional Celestions™ insure smooth classic response 
over the entire spectrum of guitar tonality and playing styles.  

 

•

Variable send-receive effects loop. Easily adjusts to virtually any signal level of floor or rack-mount device on 
the market regardless of input/output impedance.  

 

•

Front panel "Mix" control allows mixing of processed signal ("wet") from the input of the effects loop and the 
original ("dry") pre-effect signal. This type of signal mixing is usually done via an outboard mixing console 
and adds dramatically to the flexibility of effects use.  

 

•

Rugged Ozite covered all-plywood enclosures for exceptionally long life and good acoustic isolation proper-
ties.
