Exporting BUNDLES & PRESETS from Spider IV 75 to Spider IV 150 (back and forth)

[EarthSuburb]

The BUNDLES and PRESETS files which can be saved and loaded to and from your computer using "Spider IV Edit", have the exact same parameters structure (that I won't detail here), at the EXCEPTION of ONE SINGLE DIGIT in both BUNDLES files (.s4b as file extension) and PRESET files (.s4e as file extension).
The BUNDLES files for the Spider IV 75 have "02" as exadecimal value in the 12th position from the beginning of the file, and the BUNDLES files for the Spider IV 150 have "04" as exadecimal value in the 12th position from the beginning of the file, as shown in the scre en copy about BUNDLES.
The PRESETS files for the Spider IV 75 have "02" as exadecimal value in the 20th position from the beginning of the file, and the PRESETS files for the Spider IV 150 have "04" as exadecimal value in the 20th position from the beginning of the file, as shown in the screen copy about PRESETS.
You can export a PRESET or a BUNDLE from on amp to the other, BUT, you have to edit the PRESET or the BUNDLE  file in order to have the appropriate value in the position previously mentioned.
After exporting, you will have to edit the "volumes" of the presets, because both amps have a different responses in terms of "balance of volume" between different amp models.

Right, and that would require the presets already be in the amp and then off-loaded using Spider Edit.

I far as I know, those files were never made available to end users as separate item.
