ATX-100: 100-watt all-tube three-channel amplifier

The ATX-100 is our newest and most powerful all-tube guitar amplifier. The three-channel ATX will take you from shimmering cleans with just the right touch of its lush spring reverb, to an all out metal assault. The clean channel is designed to stay clean all the way up unless you push the master volume to get that nice warm power tube break-up. The clean channel features a volume, responsive 3-band EQ as well as a bright switch. The overdrive section features 2 channels with separate volume and gain controls that share a 3-band EQ. The newly designed mid-cut feature is assignable to either of the overdrive channels giving you the ability for a brutal rhythm channel and a searing lead tone. All channels share a master volume, low-res (resonance) and reverb control.
