Xcalibur saturation preamp

Many folks have been asking for a preamp that can push their music production “over the edge”. Well, here it is!

This dual pentode preamp has 2 tubes per channel, one for clean gain and the other for overdrive. You can go from pristine clean to even harmonic drenched sound thanks to the dual stage overdrive. A special combination of a JFET transistor and a pentode makes the breakup even smoother than the tube by itself. And a 3-position pre-overdrive filter helps clean up the muddiness that often results when too much bass hits an overdrive circuit. First, drive the second tube to your liking, then blend it in with the clean signal, and, voila!

Whether you use it with your microphone, instrument or line signal, Xcalibur cuts through where other swords break!

The Xcalibur JC was introduced in early 2018 in collaboration with Joe Chiccarelli, a Los Angeles based producer/engineer. He was checking out the original Xcalibur at his Sunset Studio in Hollywood and requested a few mods to make the unit more suitable for his way of work: A master pot replaces the 3-way attenuator switch, OD gain (marked OD+) now has 3 stages (mid/low/high), and there’s an additional 3-pos post-drive Low Pass filter (marked ODf2). All other functions and specs are the same as on the Xcalibur Standard. See manual for details.

Joe Chiccarelli always keeps one of these units patched into his console, and here’s why:


Here’s all the functions explained:
