The Drunk Beaver Bat V2 is a mutant Rat circuit, using NOS LM308 and OP07 op-amps as well as 6 different clipping modes to give 36 different iterations of the Rat circuit, enabling you to dial in your perfect sound!
Stefan Karlsson of the Guitar Pedal X blog calls Drunk Beaver founder Vitalii Bobrov 'the master of Rat Distortion', and it's easy to see why - Vitalii has crammed so much into a small chassis and it sounds phenomenal. And he hasn't stopped at just one Rat-based pedal: check out his Bat Cold War V2 for a slightly different take on the theme.
Bat V2 Clipping Modes
The Bat V2 has 6 clipping modes:
"Boost" - A very loud signal with tube-like response and break up
"Soft MOSFET" - BS170 MOSFETs give a crunchy character
"Soft Ge" - NOS AAP153 germanium diodes; great for bass
"Hard Si" - 1N914 silicon diodes as used in the classic Rat
"Hard LED" - Red LEDs as used in the Turbo Rat
"Hard Ge" - NOS Soviet D9 germanium diodes, similar to those used in You Dirty Rat
Bat V2 Op-amp Modes
The Bat V2 is loaded with 2 both NOS LM308 and OP07 op-amps. You can switch between them to dial in the voicing you're after.
"Vintage" - a NOS LM308 as found in the original Rat
"Modern" - the OP07 chip which was used in USA-made Rats in the early 2000s, before manufacture moved to China.
Bat V2 Controls
As well as the Clipping and Op-amp modes mentioned above, the Bat V2 introduces a three-way Fat switch to toggle between Fat, Stock and Low bass response. This is a new addition for the V2.
The Distortion, Filter and Volume controls work in the same way as a traditional Rat.
