OK,

After doing some research I found that a 25 K log pot would do the trick.

Teemuk,

Thank you for your quick reply.

QuoteIs the volume potentiometer logarithmic or linear? Does it have FX loop where you could insert a volume pedal? Can you use it with an alternative, less efficient, speaker setup at home?

I don't know about the volume pot.
I don't have any other speaker / cabinet.

But my amp has an FX loop. As I already use a pedal volume for violoning effects I could fit a potentiometer in a little box connected to the send and return of the FX loop. Will this alter the quality of the sound? What do I need: 250K or 500 K logarithmic pot, resitors, caps?

Hello to everyone,

I've got a solid state Peavey Studio Pro 112 from 1995. It delivers 65 W which is useful for gigs and rehearsal but too loud when I want to play at home.
Even with the volume of the clean channel at 1 it's much too loud and it's very difficult to get the sweet volume spot between 0 and 1 by adjusting the knob.

So I would like to know if there's a way to lower the volume (using attenuator, master volume ) and how to do.

Thanks for your help.
