I built a Germanium FF clone using Dragonflys layout in this thread. http://www.diystompboxes.com/smfforum/index.php?topic=30389.0
When I play through the pedal on my amp a Modded Valve Jr it sounds really good but its a little bass heavy. Well last night I decided to take it over to friends house we ran a Les Paul and a Strat into the FF hooked up to his Carvin V3 Amp needless to say niether of us where pleased with how bass heavy the thing was. So how can I tone the bass down? I t currently has a 1K pot for the Fuzz side but I have a 2K pot I can use to replace the 1K pot

The easiest solution would be to decrease the size of the Input and/or output caps.  You could put them on a spdt switch and select for lot's of bass, or not so much

Well I tried swapping out the 1K pot for a 2k pot seems to have helped so far it cleans up alot better now than before. I think I will try out your suggestion next Mike.
Thanks

  Pull the input wire from the switch on the board side.
 or, maybe you prefer or see it as a better way...to cut the input wire for this splice-in, at the input to board wire, then no soldering on the switch, I use 1meg Pulldowns right there just for this purpose and to pulldown [ie I solder on the Rleads instead of the switch lugs.
  But if the wire is very thin, perhaps just:
 Insert capacitor into cut wire, try the same value capacitor that is the input cap to change its value [ie series two caps there].
 Try + or - any value to arrive at a place near the bypass switch where an SPST switch can be fitted, solder the capacitor across this switch. When the switch jumpers the 'extra cap, the original value input cap is default value.
 You might want that original value sometime, or change it to about thin enough and use the second setting as 'a little thinner yet'.
 It's pretty easy to de-gain to thin-tone by way of bass cut with these circuits, another way is to have a guitar volume control or pickups that work differently, rolling off the GVolume may lift overall signal that the reduced bass swamping can allow better definition in the low registers, a treble-bleed across the volume pot of the guitar allowed me use of the VControl without mudding from treble loss.
 As the signal path resistance through the pot increases, the treble bleed capacitor starts looking like a lower impedance, so some brightening is possible, this can seem like 'passive-boost' of treble.
Convention creates following, following creates convention.
