they dont mention them in the manual because they dont want to be liable for people screwing up their pedals and not knowing how to fix it. take caution, and record your original settings.

you hit the nail on the head as far as the function goes.

Eh... Um... That's news to me. I think it's 'tommyboy27' you're thinking of.

That third hand thing looks useful for my studio simply because you can control any pot with it, you're not limited to what you mod. Hmmmm.


Pot values... On the back of the pot it'll say something like '1K B' or '500K A'

The '1K B' would be a 1 kilohm type B (linear gradient) pot. Linear means it works in linear steps as you turn it, e.g. 1,2,3,4,5,6,7,8,9, etc. The '500K A' would be a 500 kilohm type A (logarithmic gradient) pot. Log means it works in logarithmics steps, e.g. 10, 100, 1000, 10000, 100000, etc.

Now say, for example, your tremeo speed control was a 1K B type pot and you expression pedal was a 500K A type pot, you're going to get some very strange things going on.

This is part of the reason why doing this mod is harder than it appears. Not impossible though, and definitely worth it, done right

Hope that helps clear it up a bit.

Stu

Yeah sorry stu, I meant tommyboy. Anyway, The pot says 470 K. So I need to find an expression pedal with a similar pot in it. That seems the hard part. I looked on MF and saw 3. The Roland EV5, Line 6, and a Moog. It doesn't say what kind of pot they use though. Should I make one? Could I use a volume pedal too? thanks.

I think my EB volume pedal is 500K - that would be close enough to work.

You can use a volume pedal with a special lead.

What do you mean special lead? Could I use the EB VP junior. It is a passive vol. pedal. I only ask cause it's smaller than big EB. I do already have a Boss FV-300 volume pedal that I use for volume control (obviously). It has 2 sets of I/O for guitar. Could I use the other set to control the Tremolo. That would be ideal cause I wouldn't need to buy another pedal which saves space and money. Thumbs up to that.

Well on a vol. pedal the input is connected to one side of the internal pot and the output is connected to the otherside. Therefore you'd need a lead (stereo jack to two mono jacks) that joined either side of this to the one you've installed in your pedal. It should seem pretty logical when you look at it.

Hope that helps,

Stu

I'm not sure if I follow. I just opened the FV-300 and there isn't a pot in the conventional sense as I know it. There is a strip and when you rock the pedal, a piece of metal sides back and forth inside. I understand it works the same, just never saw one like that. Anyway, on the pot it read "250KCx2." does that mean it is two 250K pots in one or something making it 500K? Back to what you said about the leads...Do I need to replace a jack or connect something with wire? Will i need a toggle switch to switch between volume and expression settings? thanks for clarifying.

This is one of those annoying things that I could show you how to do in ten minutes if it was in front of me, but it's hard to explain in text format.

I'm in the middle of a recording session at the moment, but when I have five minutes I knock you up a quick drawing of what I mean and post it. Unless someone beats me to it Hope that's okay.

Oh thats great thanks. A diagram would be awesome, seeing is easier that reading I agree.

Okay this is really bad, but it's all I could draw quickly inbetween takes...

Bad Diag

See what I mean about this wiring and needing a stereo jack to two monojacks lead IF you use a vol pedal.

I think 250K x 2 may mean it's a dual pot - basically two pots in one case.

Hope this helps,

Stu

Well my trouble is that the volume pedal doesn't have that round pot. It looks like this:
http://community.webshots.com/user/fridgebuzzz

It's connected to the pcb and so are the jacks. Seems strange to me. Do you know about these pots? thanks.

DOH! It's just a slider pot instead of a rotary pot. Well the good news is you don't have to mod that bit at all, so don't worry about that one. All you need to know about the vol/exp pedal is what the inputs and outputs are... so

What are the ins/outs on. If it's a volume pedal - it should be a mono jack input and a mono jack output.

Now, all you need to do is wire that jack socket on the back of the speed pot on your tremelo. Then get a cable between the two and try it. It'll be weird because from what I gather the pot in you trem is a 470ohm and probably linear and the pot in you exp/vol pedal is 250K and most likely logarithmic. This is what makes it so annoying - as every pot you're likely to find in a pedal has a different value and response from 1K linear to 1M log, there's a vast number of different values available.

Now if someone developed an exp. pedal where you could select the value of the pot, that would be cool BUT there are issues with that also.
