implementing presets

(1/2) > >>

I'm designing an amplifier based on the Orange Crush series.  The only problem I have with that amp is that there are only two presets (clean and dirty) and the tone controls are shared between the channels.  I want perhaps 5 or 10 presets, each of which uses a different set of values for the various pots.  I could use a huge switch and switch in a bank of pots, but that seems both unreliable and difficult to implement.

Has anyone on this board attempted to implement presets?  What approach did you take?

Hi Jon,, welcome :)
Not a simple project xP  You will need relays, dedicated foot control switches and a one off circuit which may require more power than the tiny 10 watt amp can deliver.
So in my observation it's *False economy* a whole lot of work for little return. :'(
When you can buy a nux pedal (or similar) with 100 user settings for under $100Au
then it's a no brainer. 8|
I'm aware that a lot of players like the idea of an *All in one* amp that does it all but it's rare to find and ones that are capable are likely to cost a small fortune. :-X

As much as I hate the idea of pedal boards they are extremely useful and cost effective.
Also allows for swap and go changes to get other capabilities. Dedicated *Do it all* Amps are not swap and go friendly.

Hi, Phil.  Thanks for your comments.

I found these

Seems that one can now setup a circuit board that usually uses a pot, and replace the pots with these circuits.  Should allow fairly straightforward presets.

I'm just playing around with this project.   And it could well evolve.


Programmable pots open up a lot of possibilities. You could even make some of your stompboxes programmable. Beware that many programmable pots don't like signals that go beyond the rails so you need +/- supplies when the pot has an AC signal on it.

Sounds like a fun project.

Although it will take a lot more than simple potentiometer changes to get useful presets.
