I'd like to do this one too.

I posted the vari-mid part of an ibanez onboard bass preamp and I amsure its almost identical. Save for the added fet.

Here you have already everything prepared:
schematic: http://www.hobby-hour.com/electronics/s ... l-zone.php
Just remove/bypass the distortion part.
Here you get everything needed too, for EUR 24,90 new:
http://www.thomann.de/de/harley_benton_ ... 20df97bda9
So we have:
$ 190,-- + $ 160,-- = $ 350,--
- EUR 24,90 ~ $ 30,--
--------------------
$ 320,-- ..... you can save by modding one of those.

I'm better at taking pictures than I am drawing schematics; so I'll still need some help on this, guys.

We can do the schema.
I never got the midrange switch cap values when I had mine.

Of what i can see we need a list of ALL the caps values. All that is needed iam not sure where your at in electronics. So forgive me if you know this allready. don't need to try and read the value with a meter or anything. Just the number written on each cap will be fine. Most here can decipher that. That way we can take that and put it against the traces and come up with a schematic. Thanks in advance. The resistor we should via the pics be able to get via the colour code although photos can be fun with that. is that red pink or blue??? Then hopefully all should be good.
What's the best thing about fat chicks and scooters? There both fun to ride around until your mates find out!

Did I miss any capacitors? I thought I wrote them all down (in a few places) on page three?pedalgrinder wrote:Of what i can see we need a list of ALL the caps values.

I think just the midrange switch caps. You got everything else.

You know it wasn't so bad...
but i forgot to make that damn list!
Plus I want to finish tracing this. it really is a great pedal.
Its also the same circuit in the Xotic basses.

You're absolutely correct. I have NO idea why I wrote green. It's obviously black. Thanks for catching that.

I wonder where you can get those little blue caps. everything else is standard fare.

As far as i can see they are just blue monolithic capacitors they come in blue and yellow. The electronics store i purchase from in adelaide sometimes has some blue ones and sometimes yellow never found any difference between them. Great for fitting and a small board where space is tight. If you type monolithic capacitors into evilbay they come up by the millions or so to speak.

Monolithic...ceramic right?

if you type into evilbay monolithic blue you'll get the exact one's. iam pretty sure the ceramic ones are higher value although they could be all ceramic i only knew them as monolithic. Might have to investigate to find out exactly.
