Today I took out C1 and put in a socket. I tried 100nF, 47nF, and 82nF. I settled on 82nF. The control is still subtle, but you can hear what it does better, and I think the low end is more in the normal TS range, instead of too much and fuzzy/wooly. Seems more usable now to me. I think it was too "flat", so it didn't really tighten up a high gain sound.
I would like to socket some of the other parts, but some of them are under the pots, so probably too much of a pain to worry about.
The more I listen to it though, I think that knob is misnamed. Instead of Tight, it should be called Clank. lol. It reminds me of the "Curve" control on my Green Rhino. It is very subtle also, but you can hear the clanky upper mids come in when you lower the knob. It basically sets the cutoff frequency of the upper mids. It don't really have much to do with lowering bass to tighten the sound.
Its just a weird take on that circuit, lol. C7 and R15 is the classic TS low cut filter, but those values only give a cutoff of 150hz, so much more bassy than a TS (which is set about 720hz). However, C1, R2, and the tight control are in parallel to that, which is kinda weird. The resistances will drop, and the capacitance will go up when you look at the combination of both paths. From my calculations, that means the highest low end cutoff you can get is about 360hz, which is much bassier than a TS. It is gonna be much muddier with that cutoff. The mod I made today should get it up to around 500hz for the cutoff which is still kinda high, but its not as muddy. Since I used a socket I might try something like 10nF or 1nF tomorrow just to see what happens. That should be about the right cutoff, but it might sound too thin because of the rest of the circuit.Hmmmmm ...... So is it the design of that PCB circuit then ?

I bought a parallel mixer. I hate how most effects pedals are a complete tone suck. This way I can add uneffected signal back in to taste.

I like this idea. Might have to try one of these in my fx loop. I run a multi fx box in there and regardless of how I set the mix in the individual patches it always seems too wet/processed to my ear.
I built myself a Parallel Mix pedal which I mostly built to run my rack effects in parallel in the loop. It works great, and I find it hard to run Chorus, Delay, and Reverb without it anymore!I like this idea. Might have to try one of these in my fx loop.

However, you need effects that can killdry or run at 100% wet. Not all units can do this, so you will have to see if yours will.
If not the unit will have a digital dry which is delayed a few milliseconds from your analog dry, so you will get a weird comb filter sound. It will sound like you always have a slight Flanger on.What's the reason for killdry or 100% wet? My current multi fx doesn't do that globally, but I can set the wet/dry level of each individual effect.
To my simple brain, if I can use a parallel mixer with individual pedals that don't have killdry, I could also use it with a multi fx. But I could be missing something.
Sorry dude, quoted you earlier by mistake and just caught it.
My above reply was meant for you. Looks like some mid late 70s Matsumoku deal. Similar to an Electra Wedge.

Many modulation, delay, and reverb pedals have an analog dry-through, like Boss CE-2, or Boss DD-3, etc.... so they don't have this issue.
Well, I tried 10nF today, and had the same, but opposite problem. The pedal was tighter and sounded good, but the tight control was back to doing nothing. It seems like there is a small window of usability. I think I am going to leave it at 82nF and call it done, lol. I don't think I have ever taken a pedal apart this many times. 82nF sounds pretty good, tightens up in a usable way, and the tight knob does a little bit in terms of bringing in, or taking away, a little bit of that upper mid clank.Its just a weird take on that circuit, lol.

For comparison, the 2nd click on the Dwarven Hammer is about 480hz cutoff, and the 3rd click is about 720hz, which should match the stock TS. More clicks cuts even more bass.
Just so you know, analog dry through is mostly only a concern (at least from a comb filtering perspective) when using a multiamp wet/dry or wet/dry/wet setup. It's not really a concern of you're using one amp or a stereo rig.Ah. Thank you for the explanation. Makes sense.

Yes, some people also prefer a parallel loop for effects on distorted tones since it seems to maintain a bit more clarity, so certainly worth taking a look into. My amps mostly have parallel and switchable loops, so I don't have to worry.Thanks for that. I was thinking of trying the mixer in the loop of my 5150 with a GSP1101 for FX. So a mono, single amp rig. I guess I like subtle FX when I do use them, so the idea of having some pure dry signal to mix in was appealing.
It will still happen with a single unit with a mono amp if you run a parallel mixer.Thanks for that. I was thinking of trying the mixer in the loop of my 5150 with a GSP1101 for FX.
