The amp design is taking shape, and it is likely to be very controversial. I would appreciate feedback.
The basic idea is to take an Orange schematic, replace the pots with digital pots, and add an Arduino to allow control of the digital pots. The Arduino would read the pot settings for each preset from a text file present on an SD card. WiFi or bluetooth connectivity would also be implemented on the board, but I would not want to have to write an Android app for just one amp. There would be (say) 7 buttons to select one of 7 presets, plus a pot for reverb intensity, a pot for master volume, a pot for amount of lead boost, and a push button to enable/disable lead boost. Very few controls at all, and none of them related to a preset (although I suppose I could put the lead boost pot into the presets). All of the configuring would be done ahead of time by editing the text file and copying it onto the SD card in the amp. Provision for a foot board would also be made (preset selects, master volume, lead boost).
I have no idea how much I would like this level of increased flexibility coupled with increased inflexibility. That is, this would be an experiment.
Any reactions?
