Earlier this year Electro-Harmonix made the pedal I’ve always wanted… the Freeze; instant-and-everlasting-sustain-in-a-box.
I don’t know how they did it (some kind of sample / loop / reverb trickery I guess) but I love it!
But there was a minor niggle from the word go; the footswitch is not a normal latching switch (press-to-start then press-again-to-stop) it’s a momentary action (press-and-hold-to-start and lift-foot-to-stop) …so why does it click every time you press it?
The constant click-click was a bit off-putting, especially if I was playing in an otherwise quiet setting but I decided to live with it… until this weekend when I started to have other problems with the footswitch.
I noticed that when I was pressing the switch down (and sustaining a note) if I inadvertently reduced the pressure on the switch a little, although the LED that shows the effect is operating stayed on, the sustained note stopped – as if I’d taken my foot off the switch altogether.
Bearing in mind the nature of this effect, that footswitch gets a lot of use, so it’s inevitable it would wear out eventually – but I confess I didn’t expect it to do so quite this soon!
I have done a little bit of soldering in the past, so I decided to take the base off the pedal to see if the footswitch looked like it would be easy to replace.
This is what I found inside the Freeze (see figure 1). It looked fairly complicated; the footswitch (which judging from the three connection points, appears to be an SPDT switch) is soldered onto a separate circuit board, which is, in turn, connected to the main board via a twin core white cable.
On closer inspection I found that only two of the three footswitch connections are actually part of a circuit, the other one IS soldered to the board but doesn’t seem to do anything else.
There’s also a strange contraption involving a spring on the left that doesn’t seem to be connected to anything – so I’m not quite sure what purpose it’s serving either…
At this point I had enough pictures and was confident enough that I could put things back how I found them if I needed to – and I decided to go head and try to replace the switch.
If you’re thinking of doing the same thing please note the disclaimer below before continuing.
I purchased a SPST* ‘Push-to-make’ switch from a local store and set about replacing my faulty footswitch.
Once I undid the nut that holds the switch in place it was fairly easy to lift the footswitch and board assembly free from the pedal (see figure 2).
I was then able to desolder the white cable from the footswitch assembly (see figure 3).
Detail (in figure 4) shows, in yellow, the point at which I de-soldered the white cable from the board. I’ve also circled, in red, the two points at which the footswitch is making electrical connections to the board).
It was then a simple matter of soldering the white cable onto the new footswitch and fitting that to the pedal (see figure 5).I’ve not taken this kind of ‘risk’ with pedals I’ve bought before, but having tested it out last night I was delighted that the new switch worked perfectly and, as a bonus, since it was a ‘softouch’ design, there’s no more click when I press it. Result!
Disclaimer: This post reports my experience. If you’re having problems with a Freeze pedal then you should contact the place you bought it from – I’m pretty sure that replacing the footswitch yourself voids your warranty! If, on the other hand, your warranty has already expired but you’re not confident making this mod yourself, I did find this US company who appear to offer a switch replacement service. If they’d been in the UK I’d almost certainly have gone to them.
Your article was a fantastic help – very much appreciated, thank you (own mod successfully completed based on your advice). For folks from the UK, the switch I used (which looks very similar to that used in your photo) is here:
Good luck all… Stay Frozen / Straight from the Fridge
John, that’s great – so glad it worked for you too – and thanks for taking the trouble to let me know.
Hi, I just did the same mod – works great! thanks for your help.
Great to hear it worked for you too Ben – thanks for letting me know! Mine’s still going strong – no problems at all.
I live in the US, where the part number/description for this switch is different.
But I just did the mod, and it’s super easy and works great! What a relief!! The switch I used was a momentary SPST Soft-Touch switch, normally open:
Thanks for pioneering this mod and posting Matt.
glad it worked OK for you too – thanks for letting me know (and for the info about the US part number, which may help others who wander into this little corner of the interweb – it certainly looks like the same switch to me).
All the best
Thanks very much for this, decided to bite the bullet and change mine out too, turned out to be a much easier job than I thought and the end result is brilliant. Finally no more clicks at intimate moments 🙂
(Can’t understand why they don’t come with this as standard!)
Wondered if you knew if I could do the same with the switches on the Deluxe Memory Boy?
thanks for your comments – glad it worked out well for you too!
Re the DMB – I’m afraid I’ve not got a DMB so have no personal experience on this one – I don’t know whether it’s possible or not, but I did do a bit of research for you and came across this conversation thread that seems to suggest that someone else has done something like this successfully with the tap tempo switch on the DMB. Obviously you try it at your own risk.
Sorry I can’t shed any more light on your question – good luck with your quest!
the spring is to ground the metal casing to the circuitboard
Thanks for your comment Tim – if that is the case I imagine it made perfect sense in the original design but my guess is the replacement switch I’ve used is grounded by being bolted direct to the chassis…
Matt, thanks for this work! Helped me and my faulty/used Freeze a lot. Works now quieter and fantastic, as I had the faulty footswitch thingy.
Best from Germany
Great – glad it helped. I still use and love my Freeze so it’s good to know this is still a useful mod / fix (and easy too!). Thanks for taking the time to let me know. All the best. Matt
