Thats brilliant thanks! I would bet many kit builders would prefer this to the 5 core with DIN or XLR connectors, its so much easier to use a simple stereo jack/mic cable arrangement. I think I might have to mod the amp to a Neutrik locking jack socket (the hole is too big now for standard jack socket). I think this should also be posted in the Mods and Tweaks forum and indeed Nik should have it available on his Mods page.

Don't thank me Nik, it was Pickmaster who did this layout.!!

Hi Hywel,

No I did not snip them.
Just using 3 conections.

Cheers

Dr Ika, I've just finished making the footswitch mods and it appears I have a problem with the LED's. I used the LED's of the original footswitch which were 12v LED's so I didn't put the resistor in series. Now it appears that they are drawing too much current since if I disconnect them the switching works fine.

So could you tell me the spec of those you used. I'd assume that a 5volt LED with a suitable resistor in series will draw a lot less current than the 12v.

Thanks for your help.

BTW I've just changed the mid cap to 50nF and the treble cap to 1nF with the intention of making it have a little more mid scoop when turning the mid pot down. Not had chance to try it yet, will report back later.

Thanks for the info, DrIka, I bought both types just to be sure just aswell really as the 'low current' types still drew too much. In fact the 2.7k was borderline for the high power LED's, the PAB relay would trip but the OD wouldn't. I ended up using 12k and now both work fine and the LED are plenty bright enough, in fact the green I'm using is still too bright.

Only problem is the way the switches are wired up, I get the PAB led light up when the PAB is OFF. I seem to recall a discussion a while back that suggested that the switch was wired wrong in the original. I'd think it was just a matter of switching a couple of wires at the relay but I'm not confident enough to know which.

150uf filters will make your bass tighter at higher volumes.

Quote from erwin_ve about the 100k-250k pot
"Od level pot 100K makes a smoother transition from light overdrive to a heavy overdrive. When the level pot is 250K the transition is less subtle."
...and also with 100K you will have smaller volume jump from clean to OD


something like that
 

mcinku, pickmaster, thanks. I'm not sure which 150K resistor to change.
It looks like one is right behind a 0.1uF cap, and the other is linked with a 220K resistor behind a 0.05uFcap. Thanks! 

Pickmaster,
    Thanks.
