Hi,
Im an ex television technician (who hasn't look at anything electronic for 5 years) and Im trying to design a circuit for the following.
I have a guitar amplifier. It has 3 channels, clean, rhythm and lead. The channels are switched by footswitches that connect to the amp. These switches run on 12V and are SPST. At the moment, there are two switches which are able to switch between all 3 channels. These have leds to indicate the status as well.
What I want to do is design a box with 3 switches on it, so I can control each channel by pressing the appropriate switch. I was thinking this might need momentary switches & some sort of latching with IC's but to be honest I have no idea where to start. At the moment each switch has a 2 core cable to connect it to the amp. I was also thinking about replacing the 2 cable set up for a single multi-core cable.
This is how the switches combinations work at the moment:
Switch 1: led on = clean channel, led off = lead channel
Switch 2: if switch 1 has led off this switch has no effect, if switch one has led on then this switch will allow you to switch between the clean and rhythm channels.
So to some up what I'm trying to do, I want to replace the current switches with one box with 3 switches on it. You press one switch you get lead channel, you press another switch you get clean channel etc.
Any help or a point in the right direction would be good.
Thanks
