B-52 ATX-100 Guitar Amplifier and LS-412A Speaker Cabinet

The ATX-100 is a super powerful all tube guitar amplifier. The ATX100 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-resanance and reverb control.
