I think the entire second clipping stage is taken out, and the input caps are higher that cause the aformentioned inherent slight clean blending

The diodes are removed from the feedback of the second stage, and the recovery/4th stage is missing...there are minor value changes as well

Close enough I suppose

So if the recovery stage is taken how does the circuit not lose tons of volume? Cause of it only going thru only one pair of diodes rather than 2 in a regular big muff?

Cause clipping reduces volume, so taking the diodes out brings it up enough that the tone stack recovery stage is no longer necessary.

Here's the schematic:

It's almost identical to the Tall Font or Civil War Big Muffs (although some places on line have the 500pF caps marked different to the ones I've seen in the flesh) bar the aforementioned removed clipping diodes and tone recovery stage.

I do clones of them as is and my Dobsky Fuzz is a cross between both with a few extras such as clipping choices on the second clipping stage and a mid control. My favourite setting on bass is in the Jumbo mode with the tone just below 12 and the mids a touch above 12. Run an overdrive into that and you're on to a winner.

So....can you mod a standard issue NYC muff into one of these things by ripping out a couple of components and jumpering the pads?

Pretty much, some component values are different (in the tone stack for example) but u could definatly get more or less the same idea as other jumbo tone bender clones

And you can pretty much get a Colorsound Bass Fuzz by keeping the stage and just removing the clipping diodes of the second stage.

and then upping the in/out and coupling caps to .22

this thread is fun

Taking out the first set of clipping diodes will get you close, just think of the extra gain stage as an lpb 1 tagged on after the effect. But really you need to change the feedback caps across the transistors to 500pF. Can't remember off hand what the coupling caps are in the reissue but if they're less than 100nF/.1uF then might be less bass but most the bass is controlled with those feedback caps.

Just to add to what Jero said, you'd need to up the feedback caps to 1n (twice as big as what's in a super/civil war/tall font) as well as the coupling caps to 220n:

If anyone cares, I started this thread because I was putting in an order for some components and was trying to decide what pedlol I'd like to build next. Jumbo TB seemed interesting, but I decided to buy some stuff to make a brassmaster instead .

Good info nonetheless, gentleman.

I built the Colorsound Bass Fuzz for my friend but it sounded a little too flubby. Per skreddy's input on that circuit, I reverted it back to the Jumbo values, changing the coupling caps to .1uf's taking out the 2.2uf's. Through my friend's rig the Jumbo circuit sounds way better for bass. It's pretty tight and full and fuzzy and heavy. I etched two of these boards and stuffed one for myself last night for use with guitar because that shit sounds so good...

I agree. Though, even still, it's a bit redundant if you've got a good muff, IMO.

And that's exactly what I don't have!
