@pelle:yeah ha ha...that'd be cool....   Wink


@ian: i like the look of that tonemender, with switching caps etc... i have a passive version on bread at the moment, but the mid lug1 has got me puzzled

because its passive....hmmmm...i'll mess around, the treble seems nice though as is, sounds a bit like satch/saraceno/ not harsh at all.....hmmmmm.....possibilities

may need a buffer on the end though...


edit: sussed it, i'm using the 'fender' stack from the calculator....its quite good actually.....i'll tweak some values and whack a clip up later...busy today...got to sort out a mates poxy pc.... Roll Eyes

Your original tone control has a Fenderish notch to it when rotated CCW.  I have thought about using the Marshal with the Bass and Mid either fixed, or with trim pots and using the Treble as the tone control on the outside of the box.   icon_cool

I can see where this is going...bass mid treb seems to work for most guitarists...it will fit in a 1590B, if not like this, then with all knobs on top. One and 2 knob eq's are a compromise IMO, so is a 3 knob, but much less so. The Marshall guvnor tone stack works well too (on a guvnor). The single tone and trimpot "presence" control on a crunch box work well, would like to give that a go this wkd too. I've found that with a 3 knob tone control, most of the parts can be mounted on the pots themselves and the rest air-wired if necessary, don't really need a PCB.

The Q5 is a buffer so it should drive the tone controls no worries, but a buffer or gain stage on the end might be needed, which you did mention Rob.

I'll see what I can build this wkd, speculating gets me nowhere.

@wgtp: cool, of course the xbananaanananananaov stuff.....where the whole thing started....full circle eh!... Wink

i'll give that  mid/hi/lo a go and see how it sounds....cheers!.


@ian: yeah BMT is ideal i guess, as long as there isn't too much interactivity with each pot affecting each other....which this fender one does somewhat....

but it has the foundation of a pretty good stack....if tweaked..

cool stuff guys!!!.... Smiley

If you've only got two controls that can both cut and boost, you can get the effect of boosting the third one by cutting the first two and adjusting the overall volume to fit and vice versa. Kind of like what you have to do to get mid scoop sound with a bandaxall tonestack -> boost the bass and treble and you're left with a smiley face.

Ok, this should be 1590A'able. Go for small pots and submini switches and place the jacks high and the stompswitch far down, watch for height of components (may I suggest going for multi layer ceramic caps?).

The layout follows version five quite well, wiring should be "easy" looking at that layout.

Some pics, progress has been made, despite missing some minor parts like a stereo input jack, knobs, paint job, etc...

I do like the 100K for tone control. Sound is very good, but I have a hum problem when not playing that I can look forward to in the morning. Nite all. Smiley

The Valve Jr. I play thru doens't have tone controls, so I simmed this one until I got this tone control to mimic the Treble control of the Marshall stack, as well as the mid-range dip.  It's a little flatter than the standard one, so it should have some more mid-range to it.

OK



Still unverified, and the extra solder pad still hasn't appeared on the layout (just on the transfer). Now D'Astro, go buy some 1590A's and start building  icon_twisted
