Hi fellas, I'm replacing the footswitch on an older Cry Baby for a friend. After googling, the suggestion that seemed the best was to de-solder, and then clip the leads off where they come through the board, and then finish applying a little heat to wiggle the switch out. Anything else I should know?
This looks to be a simple ST Carling switch, similar to what Doug sells, except the leads/solder tabs are on the bottom instead of coming out on the one end. The only switch I've been able to find that will fit is a TP kind; 1 set of leads on bottom, 1 set coming out on each end.
Anything at all you think I should know would be much appreciated!

Why do you need to mess with the board? My old Thomas Organ Crybaby has a SPDT push on/off switch that simply has 3 wires connected. Simply unsolder the wires at the switch. Is yours different from this pic???

Hi Sluckey, yes it is. There is a small PCB with just a few components on it - 2 LEDs and a tiny resistor or two - and that is attached to the bottom of the footswitch. The switch then mounts to the metal housing as normal, but the LED's come through the 2 little holes near the front to indicate on/off and whether boost is activated (IIRC).
I did remove the solder, when I get back home I'll take a pic and post it.
Almost forgot, it is a Dunlop, model CH 11040, rev. 3 .... according to the bottom plate. Thanks for the reply!

Sorry I haven't followed up on this sooner, but that danged work got in the way. Anywho. Attached is a pic of the board and switch. Arrow points to the solder points on the bottom where the leads poke through.
After more googling, I dismantled the switch (carefully) so I could heat up each lead individually and wiggle it out. Everything is waiting for the new switch to arrive. Ended up ordering from Banzai over in the UK. Dunlop is "temporarily out of stock".
It is a Crybaby 535, not the Q series. No idea what the model # at the bottom of the plate means.
And there ya have it. :smiley:
