Is the Jose Mod Just a Clean Boost?

[Lechmere]

So, is the Jose Mod just an internal clean boost, and if so, why not just run a clean boost pedal in front of your amp rather than getting it operated on?

No, it's not. If you're talking about an original Jose mod it's an extra tube gain stage in front of the bright channel of a 1959 with a switchable master pre or post ton stack, sometimes with diode clipping on the master.

There are also tons of variations by different modders with pre tone stack masters with diode clipping, sometimes with or without an extra gain stage and various other mods to the usual Marshall gain stages.

Are there lots of possible options to how the extra tube gain stage is added in front of the bright channel? Like some related parts values? It just seems hard to reconcile such a conceptually simple mod description to the vast number of Jose "style" mods out there. And I'm not talking about together with all the other mods, but just what various builders advertise as their basic Jose mod.
