M800 trimmers, can I use 50k?

I believe I know the answer to this, but thought no harm in asking. So excited about getting this build going, only to realise I forgot to order 100k trimmers. Would 50k’s have enough range to get the jfets to 4,5v?

Members have a hard time dialling this pedal in with 100k Trimmers so I would not use 50k at all.
Trimmer on bottom right is a Tone trimmer, It is critical in matching your amps overall tone.
I have alot of time invested doing this build & genuine J201 Jfet's must be in spec or it sounds like Crap!
If done Correctly, It is the BEST MIAB!!!

Cheers mate!
I definitely take your word for it! I’m getting pedalpcb’s own j201 smd-converts since I’ve heard so many horror stories about fakes from ebay. Suppose I’ll just have to get some 100k’s than. Luckily I’m getting more pcb’s on monday to keep me busy while waiting.
