Hello, I have two FX pedals (9V DC) in loop of my guitar amp which I control using switches on my floor pedal board. I control amp's reverb and its channels too. I used 3 m long ethernet patch cable and couple of female JR45 adopters. (There are 8 leads in cable, I'm currently using 7 of them) PROBLEM No 1. It looks like I pushed my system to its limits because it wouldn't work with 5 m cable when I play on bigger stages. (I know there are different type of ethernet patch cables standard/crossed etc, but I double checked my cable to be sure wiring was correct) I intend to put couple of mosfets in my circuit. I understand the principle but I don't know how to select the right components. I'll place them in same box with my pedals so signal would have very short way to go. Now, I am afraid that mosfet wouldn't function because of cable length. I need a mosfet (hopefully 9V DC) which would function with this cable (5 m long patch, I don't know excaly its square area but it should be easy to find out) Can I compensate the cable length with higher voltage? PROBLEM No 2. I would like to implement light diodes on my floor pedal board but I don't know how to do that since some of my pedals are controlled by momentary switches. I tried to find "hybrid" double switches ( Latch + momentary) but I couldn't find them. This has been done before but I just can't find it. Problem No 3 How can I order 9V mosfet? All shops offer3V, 4.5V, 5V, 12V, 24V... Data sheet says there are 9V mosfets.
