What, if any, pedal components are currently hard to source?

Stompboxparts has 1044s. I grabbed a few in my last order just to make sure I wasn't completely out!

I am now lamenting the lack of Lumberg jacks.  None of the huge suppliers carry them, and they don't seem to have a distributor list on their page. I put my email address into the BLMS web page to be notified when they got them back in stock.  Got the email today, but I was too late to grab any!  They sold out again in just a couple hours!  I have two builds stalled on this.

They have Lumberg jacks at Tayda, but they are $2 a piece.  I was planning to order some from Lawrence, good to know they are in short supply.

Vacuum tubes are starting to get a little trickier to aquire.

Had.  They are out of stock as well, unfortunately. 


I have good news though!  Lawrence has tons of stereo Lumberg jacks.  The ring contact can be ignored or removed easily enough.  I just ordered 10 of them.

Charge pumps... TC1044SCPA has dried up and Mouser's expected restock is in January 2023!

MAX1044 and ICL7660 are a little easier to find, but quantities are low and dropping. Fortunately there seem to be plenty of LT1054s, though they're a bit more expensive.

Yep, the delivery date has gotten pushed out on those a couple of times.

We have had issues getting some of the Hirose headers that we use.  They are dust.  There currently isn't even a predicted ship date.

Stomp is parts has loads of TC1044 and LT1054.

If they had them at the time you posted this, they are gone now. 

Lawrence still has 1654 of the stereo ones in stock as of this minute.

Damn! They were in stock when I posted. I got an email about a week ago that they were back in stock.
