Hello, I have already bought a Marshall code 25 (yesterday).
Unfortunately I overwritten the fx #49 on #15 an I don't know how re-obtain that fx 'cause I very like that.
You can completely reset all the presets on the CODE by holding the down the Amp button as you turn the amp on, and then hold Exit/Store to confirm reset.
So you need #15 Lead Tone?
Gain-10 Bass-2.3 Vol-4.2 Mid-10 Gate-4 Treb-10
Pre Dist "ODR" D-6.3 T-10 L-10
Delay "Multi" T-408 F-7.1 TAP -1- L-5.1
Reverb "Hall" D-4.5 Pre-5.1 T-7 L-4.6
If you go to the marshallcode.tools website there are a bunch of presets, including all the factory ones too.
