Rangemaster pot question

Krinor · September 30, 2007, 05:58:52 PM

Hi,

I just finished another Rangemaster. I built it on the GGG board and followed this layout:

Could someone please take a look at this file and tell me if something is wrong with it ?
Somehow it seems my potmeter is reversed. Full gain at far left. Turning clockwise lowers volume/gain.
Also 10k doesn't seem to be ideal for this circuit ? Any suggestions will be gratly appreciated.

Hi,

Don't forget this is a PNP circuit with the ground being 9volt so somethings will look a little weird

Just reverse the connections on the two outer lugs of the pot. It's just wired backwards, no big deal. 10K works fine and is the original value but lately I've been building them with 25K pots and I think they sound better (a little more gain maybe?).

I personally would leave the pot out altogether and just run at full boost all the time.

Now there's an idea!

That's how I roll.

Some stock RM have a 25k pot instead of the 10k for a more agressive sound.
One of my RM clones has a 25k pot and optional a 18k R that can be switched in (parallel with the pot) for that classic sound.

Whenever I hear that line I think of Jack Black from Anchorman after he punts Ron Burgundy's dog Baxter off a bridge.

Everything on 11!

That's the way I roll!

Rock on!
