The SOS50 Back To The 80s pack contains 11 captures of a 1981 Inventions LVL in each of the ToneX, NAM Standard and NAM Nano formats. (Full details above.)
 
The second 1981 Inventions release, the LVL is, in the words of 1981 Inventions, ' a professional low-gain device, which achieves overdrive gain ranges with a new and unique circuit. A combination of light clipping and op-amp push gives the pedal a unique sound and gain structure. 
 
It works great on bass, which is what FULL-RANGE refers to. It also stacks with anything, makes most fuzz better if you put it after, makes most overdrives better if you put it before. It’s also great if you hit the front end with a little boost!'
 
Impressive!
