Description

[IMPORTANT] These are new captures that use Céline, a new SPICE-based realtime circuit simulator. This upload supersedes the old one that were made with LiveSPICE, but the latter will remain available for posterity. --- Ampeg VH-140C. A legend in the old school death metal scene. Higher ESR ratios than I expected, but at least the asymmetrical diode clipping is captured. ・Channel A - overdrive to high gain distortion. ・Channel B w/ Bright switch - very clean to low gain. [LEGEND] ・ChA - Channel A ・ChB - Channel B ・BR - Bright [NOTES] ・All the models are captured with 16x 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.

Hello ! Your project is really interesting and a very clever use of both Céline and NAM. Thank you for using Céline. Don't hesitate to reach out on reddit or GitHub, or even email, if you have any issues ! We have read about some issues on there, we plan on working on those ! We want to improve op-amp modeling as we know this is a weakness of Céline right now.

UPDATE [12/20/2026]: Celine was updated to v1.2.0 and I did some new captures to check if the transistor modeling has improved, and I can confirm that it does. Oversampling goes up to 16x now as well so that alone warrants the update. === UPDATE [10/16/2026]: Did some further experiments and fixed the biasing for the non-inverted 4558 op-amp stages to retain the intended behavior of the amp. The input response should be ACTUALLY fixed this time... === UPDATE [10/13/2026]: The input response was not accurately represented in the old NAM captures with higher input gain, so I replaced the first op-amp stage with a JRC4558 from the schematic file and retrained the amp channels/variations. This should be fixed now.

hi my friend, thanks for this one! any possibility to train one Victory V130 The Super Countess ?
