JCM800 Hot Preamp - Marshall tube head emulation
JCM800 Hot Preamp is an emulation of a preamplifier stage of one of the famous Marshall tube head for guitar.

Made several modifications to the original JCM800 preamp circuit to improve its sound. Every single component on the signal path of the real analog circuit has been took into account and modeled in the best possible way to match the original sound, keeping an eye to CPU performances and real-time playability at the same time. JCM800 Hot Preamp is meant to be used as a guitar preamplifier for live playing and jamming, tracking or mixing.
  • Dynamic ECC83 / 12AX7 triode analog modeling.
  • Two different Dynamic ECC83 / 12AX7 triode models.
  • Tonestack full coupled with the gain stage.
  • Mono / Stereo processing support.
  • Selectable oversampling rate (up to 16x).
  • Global input / output level controls.
  • Double precision (64 bit) floating point mathematical model.
  • Fully automatable controls.

Buen crunch, similar a un clásico JCM 800

Whaou! en combinaison avec le Mercuriall Cab v3 c'est juste le meilleur son que j'ai réussi à obtenir de mes guitares, avec une attaque qui a VRAIMENT du punch. Toutes les distorsions sont précises, du rock vintage au métal. Même mes chers VST LePou me paraissent ternes ou brouillons maintenant... Et Mercuriall fait aussi deux pédales la TSC 1 et la Greed SMASHER qui sont toutes les deux très intéressantes. A essayer d'urgence si vous ne connaissez pas encore!

Cubase 9 blacklisted this on startup... Shame...

From mercuriall.com, download the zip that has all *.dat files ("JCM800 Hot Preamp v1.3.dll.dat"). Extract this path right under where you have "JCM800 Hot Preamp v1.3.dll". Now go back to Cubase 9, open Plug-In Manager and re-activate the blacklisted file. Run a re-scan - as you can see, Cubase will NOT re-list that plugin. That is it!

I think this is the bee's knees... I use it as a base for many of my sounds, combined with Boogex it's pretty awesome.

Runs too slow on my resource-poor PC and gives little distortion. Try Emissary, Doctor Crunch or another plugin with fewer Mb if you have a lower-end machine.

Cubase 5 won't even load it.

Great simulation JCM800 on steroids, takes everything from AC/DC to thrash metal!

It makes my DAW (Presonus Pro 64 Bits) crash at startup every time I try to use it. And I think it is a little bit strange, because 'Mercuriall' has also produced the other plugin (Harlequin-Preamp-WinVST-x64) which does exactly the same.
