Series V RangeMaster 

Owner’s Manual

 

 

April 2020 

The RangeMaster should be the only device between your guitar and your amp.  
Because it is a PNP device, and because of circuit peculiarities, it doesn't do well 
when connected to other boxes.  You won't hurt anything if you try multiple devices, 
but you probably won't like it. 

The RangeMaster likes tube amps.  It is not so fond of solid-state amps, and you won't 
get the best performance out of the unit when plugged into a solid-state amp.  This is 
true of hybrid amps as well, like the Crate Palomino, or the Peavey Classic 

 

I hope you have many years of enjoyment with your RangeMaster.

 Thanks again, and 

Best Regards,
