Randall Warhead X2 Preamp (Celine2NAM) | Calibrated

[REUPLOAD + WITH CALIBRATION] Céline has been updated to v1.3.0 as of 10/29/2026 and it brought significant changes and improvements to its simulation engine. The biggest leap for this was with the op-amp and transistor models, as the clipping behavior is now preserved when trained and captured. As such, it's significant enough to warrant the reupload. Also, as you can infer from the title, all future uploads will be calibrated from now on. ・Send Level is +12dBu, as it is the expected value for the TONE3000 plugin. ・Return Levels 　。Clean Channel: +19.4 dBu 　。Overdrive Channel: -19.7 dBu 　。Overdrive Channel [Fry]: -33.8 dBu --- [IMPORTANT] ・These are new captures that use Céline, a new SPICE-based realtime circuit simulator. ・This upload supersedes the uncalibrated captures. --- Randall Warhead X2. As per @frozenmammoth's request. Very happy that this circuit is possible in Céline, although I had to substitute the TL072's and 2N5484's with Ideal op-amps and 2N5457's, respectively. Despite this amp being affiliated with Dimebag, I'm pleasantly surprised that it's much more versatile than what it would lead you to believe. The default settings make it sound more like a hard rock amp like the RG100, but the overall topology and controls are definitely more akin to Dimebag's RG100 setup with all the other rack units/effects, but in a single amp. Really cool design. ・Clean channel - Very clean. Can be shaped drastically and pushed to have a bit of dirt because it shares the same signal path with the Overdrive channel, sans the JFETs and clipping diodes. ・Overdrive channel - Lots of gain. Unique topology too with how it uses a combination of op-amps and JFETs for the buffers and gain stages - preamp saturation from the Furman PQ3, the RG100ES red channel JFET topology, and an active EQ section that's similar to using an EQ pedal in the FX loop. 　。Also has a "Fry" switch, which adds another JFET stage for additional gain boost and saturation. [LEGEND] ・CLN - Clean channel ・OD - Overdrive channel ・FRY - Fry [NOTES] ・All the models are captured with 4x oversampling for the highest quality possible. ・All the controls are flat so you can hear the amp as it is with neutral settings. I may add additional captures with "ideal" settings, but that's not a priority for now.. ・Should you wish to push more gain into the captures, use a separate gain utility/plugin and a clipper/waveshaper/limiter with a ceiling of -0.1dB or less before your NAM loader to prevent nuking the models if the input signal gets too hot. === Céline: https://celine-audio.github.io/CelineWebsite/ Céline .celsch schematic files: https://github.com/MARKTHERENCE/Celine-emy-Circuits === There has been some interest for me to have an option for people who'd like to donate for my work, so here's my PayPal link *only* if you feel generous: https://paypal.me/83ennui Making these captures take a lot of time, from researching the schematic diagrams (whether original or reproduced with certain degrees of verification), to cross-referencing from various gear presentations and demos, and several passes of training the captures to determine the adjustments needed with the Celine models/components for the most accurate/ideal simulation possible.
