Rangemaster set boost, control tone?

[msurdin]

I am trying to build something like the rangemaster on the rangemaster board from GGG. What I am wondering is if i can have the boost pre set inside but then have a outside tone. I just want it to go from bassy to glassy. 
I tried installing a tone control once but it had massive volume loss. Is there a way to do this and have no vol loss?

Thanks alot!

I used the obsidian tone control with little signal loss, I think that
1M resistor make it. So, take a look, After final .1uF capacitor:

I'm trying to make this more like the bsm or booster. How would I wire something like that to the GGG rangemaster board?

You could do the kind of tone control I've seen where you have a fixed small value input coupling cap and then a pot that lets you "sweep" in a larger cap in parallel with it. This would let you smoothly adjust it from a treble boost to a full boost. I forget which circuit it was I saw that had that, but I really like the idea.

I think that it will make things clear, dont remember where I got this
image and dont I dont find it again in layout gallery, but was there:

Just add at the end of circuit and play with values. You can use duncans tonestack
calc and see the tone curves before build: http://www.duncanamps.com/tsc/index.html

So, a lot of things to play with this sunday...
Thanks

do i have to have a board for that or can i just put the caps-resistors straight to the pot and on to the wires?

Can I jsut replace to tone pot with a internal trim pot? Do those have 3 solder points like reg pots? Can you reccomend a good kind?

Thanks!
