Deliverance upgrade?

I have a Fryette Deliverance 60 II and love it.
Is it possible to have it upgraded to have the II+ feature which ‘decouples’ the 2 gain controls to allow a ‘separate clean channel’ (so to speak)?

Hi,

The DII cannot be changed into a DII+.
The faceplate is different, so there is no way to convert it.

I just used my DII 120 for a show and the clean up from the guitar vol worked beautifully.
