Boss BD-2 Blues Driver

it's kind of a one trick pony. but its a damn fine trick

Using for light gain with a Telecaster. Works great!
Quality BOSS build... as usual
(They even include a battery :)

Don't be fooled by the name 'Blues driver'!
It can deliver much more than just a blues sounds. Actually, it is a very useful stompbox for a wide range of styles - blues, blues-rock, rock and classic metal.
Technically it is not a classic overdrive or distortion with clipping diodes inside - it is a kind of fuzz. There is no op-amps inside!
I would recommend it for all levels of guitarists, harmonica players and people who want to add some power to synths.
It works perfectly alone or together with other overdrives (just place it after Screamer or another BD and you will hear tons of saturation).
BD-2 is a very uncommon pedal and one of the best Boss products ever made.
