CON 67
The condenser "67" can be heard on the biggest pop and rock records of the '60s, '70s,
and '80s. This tube condenser mic has a wide frequency range without sounding harsh
or bottom heavy. It has a gentle upper midrange that's great for distorted rhythm guitars.
DIRECT
In direct mode you get the raw sound of your amp, without a guitar speaker, while still
responding as if the amp is driving a proper reactive speaker load.
