I'm just about to order the parts for my Sunnbeam, the PCB has been on the shelf for a few months.
Looking forward to finishing it.

I wonder, is there any chance of a dual channel Sunnbeam, like the Beta preamp?
Maybe something that would fit in a 1590D, two or three footswitches (A/B channel select, both channels and maybe a bypass footswitch).

I don't think it would require all the CMOS/JFET channel switching, that's just to enable remote control.

I think if R18 were replaced with two resistors, you could simply ground the point where they join to mute that channel.

Although the builder can choose whether to build as a Beta Bass or Beta Lead, it'd be cool if one of the channels had a switch to select Bass or Lead.

That with a tuner would be almost a perfect pedalboard by itself!
