I too was looking for upgrades to do to my V181 and found this on a review:
"No problem with volume control but I'm a upgrader.. I think it would go better with a step resistance volume control.
This is the link for the one I would change.

I don't know which one.. I hope somebody can help me.
Thank you,
Matteo"
I am not sure of what resistance to order and how well it might fit into the case without significant mods.
