The Scrambler - Octave Fuzz kit

    To answer the question about diodes without desoldering them:
    D2: 1.127 - 0.583
    D5: 1.086 - 0.573

    Everything is ok after 3 hours of playing with my buddies.
    No more background noise.
    It's very fat, less precise than the Scrambler Bass Overdrive, but with a lot more overdrive and reserve. In the mix, it's great. :thumbup:
    I'm going to do some more tuning with the R12 which has a huge influence on the sound, attack and sustain.

    Very cool of you for all your advice, the problem is solved, probably from re-soldering the 3 pots as smellslikebleach had indicated... :thumbup:

    Hi,
    It was short lived, back to square one.
    The high pitched noise (distant hiss) is back, it's messy with no definition even with R12 set.

    I can't see what to do about it except to hit it with a hammer!

    I can't answer the question regarding C10, but the other rewiring will result in the same circuit with a different layout ;)

    Hi,
    I'm going to remove C10, D6 (what is its function???) R12 + R15 from the circuit and replace them with a 4.7K and shunt the volume.
    Another idea, recommend all the components to install them on turrets which will be more practical for possible modifications.

    D6 is the only protective function if the power supply is incorrectly connected.
    This is especially important for users who really have no idea what they are doing.^^

    Hi,
    I'm trying to get closer to the original circuit by eliminating Volume, C10 and replacing R12 and R15 with R4.7K.
    D6 remains for safety as it has no influence.
    Since I'm not satisfied with this module at the moment, I might as well try to find out what's wrong with it.

    What do you expect by replacing a resistance between 0,47k and 5,47k with a static one of 4,7k?
    C10 will smooth out the power-supply, so I wouldn't recommend to remove it. Just remember, that at the time the original circuit was designed, no digital effects or Buck-Converters where used on the same circuit which may backfire noise into the supply.
    If you want to get closer to the original you need to make sure to find exactly the same transistors and diodes.

    I don't understand anything anymore:
    R17, R19 disconnected from +9v, C8 and T5 removed, Shunt between volume centre point and balance going fine on OUT.
    The volume works and if at zero, no sound....
    It's like before by disconnecting the volume circuit.
    Did I forget an episode?

    To repeat Simon: What do you expect?

    We suggested you to try out different Transistors and Diodes.

    But you decided to remove parts from a working pedal with a improved circuit without the knowledge of the functionality of the removed parts.

    I’m expecting that you aren’t going to reach your aim of a good / original sounding pedal with this.

    You have two choices. Build it like it’s planed.
    Or buy or build yourself a original or non improved clone of pedal.

    I just wanted to remove the volume of the circuit which, as shown on the diagram, is added.
    As it is very violent, it is not possible to dose correctly, hence its removal (at first) to understand why the sound is rotten.
    Even disconnected, it still works !!!!! ?(
    There is a problem...

    This kit should work without this volume, just look at the diagram.

    You don’t get the point. There is a reason for every part in this kit. If you want a non volume original, go and build it on you own with strip grid board. ;)

    But don’t ask why it’s not working because this kit is intended to work with the hole circuit and parts.

    Well, I have to admit that the schematic does not match the PCB from what you tell me.
    We'll stop now, we're going in circles anyway.
    I'll do it another way, thanks for reading.

    I have a different idea: maybe the pedal kit doesn't sound right to you, because there is a bad contact or an additional unwanted connection. A really nasty thing that I might have in some own builds is, that having a problem in the build doesn't necessarily mean that the pedal isn't working. It might just not sound as it should.
    For example I still have trouble with my vu-tron pedal. I guess it works but not entirely correctly.
