A new and improved Cub, with even more amazing boutique tone.

Bad Cat raises the bar and offers an update on the classic Cub circuit. The all-new Cub III features a switchable A or B valve in the first position pre-amp. You can select between 12AX7 or EF86 pre-amp tube by a toggle or foot switch. This feature is drastically different sonically in gain structure, and character from any previous Cub models.

Bad Cat added a selectable gain on the bass and treble tone stack to run hotter, or choose to stay in standard Cub mode. This feature can be used as a classic gain boost. Combine this with the EF86 pre-amp and now you're in territory previously unavailable from older Bad Cat Cub models.

The engineers at Bad Cat refined the reverb circuit to get a deeper, fuller and more plate-like reverb. A two-button footswitch is included. Button one controls the selection of the EF86 or 12AX7 pre-amp. The second button offers the ability to punch in the added gain on the tone stack. With the footswitch, you can go from chiming clean to crunch, and all the way to the wide open.

Patent-Pending K Master
Gain up the power amp section while leaving the pre-amp sparkling clean? Yes. Imagine getting a full 15 watts of clean headroom out of a 15-watt amp, or a full 30 out of a 30. Turn down the master volume to bedroom low all while maintaining your tone intact. Not only is this possible it's also useful for guitar players.

Power amp gain is different from pre-amp gain. It feels, sounds and even looks different. Master volume has always been misnamed. It should have been called master attenuation. Until now master volumes were unable to do anything, but attenuate. The drive to the power section was always dependent on the drive coming from the pre-amp.

Now Bad Cat has figured out a way to separate the pre-amp from the power amp gain, and calling it the K Master. Before this you couldn't drive the power amp hard without pushing the pre-amp into saturation. The K Master patent-pending technology has allowed us to re-invent the concept of the master volume. Bad Cat is now offering the K Master in the Cub III Series.

    Comments about Bad Cat Cub III 15w 1x12 Guitar Combo Amp with Reverb:

    Been playing for over 30 years. Had a Bad Cat Cub 1, this is so much more versatile, so many more tonal variations. These amps are overbuilt! The best quality money can buy! MF was very helpful and gave great service! Thanks MF!
