looks like theirs already a blue 3pdt.
i'm pretty sure all electro harmonix are true bypass as of 2007

Hallo, I can confirm that the pedal is true bypass. The switch is a 3pdt and, if you take off the battery, the signal pass trough in bypass mode.
I recently opened mine to take some pics of the circuit: a guy in the request folder asked for it. Right now I don't know were the tread has gone, probably I will post here.

This pedal looks like a real gem, man. True bypass out of the box?
I play bass, and I'd like to use this pedal more without taking out all of the mids and lows. Are there any mods I can do to give this pedal more life for the bass? I've heard that swapping out the input cap would be great. What else could I change?

I got some pics.... they are very bad (it can be me or my camera, I suspect me ), hope to be helpful to someone.
I really like this pedal, at first I thought it had too much treble (using it at home) but with the band I find that it just has the ability to cut through.
About modding the thing for bass.... well the idea about the input cap can be a good one; it would be easy if it was not smd, you just can solder a cap in parallel with the existing one (in this way the mod would be easy to undo). being smd I really can't tell.... By the way, which one is the input cap?

Damn. I've never cracked mine open. It looks pretty dismal. Thanks for the pictures.

You know what, though? Why exactly don't people want to deal with SMD? I mean... all it means is that we use lots of flux and a few different techniques, right?
If I had the schematic, I would give it a shot.

I'll try my hand at it. All I need is the schematic. Has anyone got a redrawn schematic of this particular circuit? (Or is it similar enough to the Micro MM or Original MM to get by?)CHEEZOR wrote: For me, I don't want to deal with it because I would have to buy a whole bunch of new parts just to try my hand at it.

Smd components looks difficult to deal with from a diyer point of view.
The pedal works very good though, better than a modern chinese rat for my taste; it has got a lot of basses and with the gain at a minimum it is a good overdrive too.
The last position of the mid switch is really useless (personally I would leave this completely out).
Is there a schemo for the standard metal muff? probably it is the same with just a fixed eq.

It's not bassy enough for me, but I like what it does with mids (with the scoop turned off).allesz wrote:Smd components looks difficult to deal with from a diyer point of view.

I'm probably going to swap out C1 with a higher value cap. I'm not good at understanding schematics, so I can't quite tell what else I should replace in the signal path. I'm sure that simple change will make a world of difference. I'll report back with the results.

in a circuit this complicated, simply replacing an input cap could have a lot less effect than compared to something like a 2 transistor fuzz. you have to take all of the following coupling caps into consideration as well. in a fuzz face, you only have input and output caps, so it will have a huge difference. with a TB, you have one more in between the two. I haven't seen this schematic, but I'm sure there are several.

This is a link to a schemo to start with.

I prefer to spend the damn 40 Euros to buy a factory built one, but it is interesting to look (understand is a big word in my case) how they do it.
Anyway it seems that I should buy a bigger breadboard to try to build this one .
