The 333XL/333XL-212 is the big brother to the 333 Series, with four key additions:
Overall active Presence control.
Comes loaded with EL34 power tubes for a more compressed, tighter midrange.
Noise Gate on Lead channel. This is an ANALOGUE gate that will never close or shut you off in a clean passage. It is designed to decrease high frequency noise and hiss without changing your tone and it works loads better than a lot of competitors' gates.
XL switch on Crunch and Lead channels. The XL function will add more "chunk" to your sound. You can add some thunder to the combo version to more closely emulate a 412 cab, thicken the sound of single coil pickups or add sustain to single-note melodic passages.
Like the 333, the 333XL also features 3 fully independent channels: Clean, Crunch and Lead, each with its own volume feeding the overall master volume.
XL switches on the Lead and Crunch channels for killer low end control
Adjustable Noise Gate available on Lead channel
Fully independent Equalizer sections for each channel with dedicated Bass, Mid and Treble control
Classic Presence control for efficient midrange sound shaping
