Volume Pedal Question

Last weekend I snagged a cool little piece of gear from the local craigslist. A Rupert Neve Designs DI box.

It may not look like much, but holy crap does it ever make my guitars sound nice. And warm.

So now I'm looking to change my rig. The one that I use to connect to the PA. The new box replaces the Fishman box
I had been using, which had a volume boost switch. I'm thinking I want a volume pedal this time around. Something
that adds absolutely nothing but louder when I need to be louder. But do I get a 250k or 500k pedal?

Can anybody recommend one?

Hello


First two questions:
- what kind guitar are you connecting - electric - acoustic w/wo preamp etc?
- do you wish the volume pedal to have effect on PA-send, too - or only to your stage amp?


Assumption #1 - you're pluggin an acoustic guitar w pietzo in it:

That nifty DI-box seems to have exceptionally high input impedance of 2,2M - ( Megaohm ) - which probably is the reason of that nice and warm sound.

If you put the pedal between the guitar and the box - your guitar will see the impedance of the pedal - which is low compared to DI-box - and you will loose that sound.

If you put the pedal to the parallel output - you will again load the guitar output with that impedance because the jacks are parallel.


Assumption #2 - you're pluggin electric guitar in it: 250k & 500k are both high enough not to ruin the output of electric ( or acoustic w preamp ) - I would still go w 500k to keep damping factor as high as possible.

After all it can well be, that the great sound is mostly due to fine circuitry design - not that much impedance related. In which case any pedal will do.

Thanks for the thoughtful response!

I am plugging in piezo-equipped acoustic/electric guitars. Usually my Guilds (Doyle Dykes or Peregine) and both have built-in preamps. This is
the home-based rig and goes into the PA only.

I have a buddy who plays through volume pedals all the time. I'm thinking I may try to borrow one or two and see what happens.
