The Bad Cat Black Cat 15 is dripping in three dimensional cleans. Go from soft chiming breakup to thick complex gain. Running in Class A, this amp oozes harmonics. Channel one is built on a 12AX7 treble, bass and cut tone stack for a warm and sweet tone with just the right amount of mid push to cut through the mix. Switch over to channel two for a more aggressive, hi-fi sounding EF86 preamp. The EF86 can be switched between the five-way tone selector or the bass and treble tone stack. The tone selector offers a selection of five-tone caps and enables you to adjust the amount of low end content to fit the guitar or situation. Global cut and separate master volumes for each channel can be switched in or out.
