Hey guys, just finished up my Boneyard build... everything seems to be working perfectly except that my Boost pops loudly when being both engaged and disengaged...

I installed the BOOST 3PDT switch under the 1590BB part of the docs.. I used a A100K pot with 22k resistors on the pot and the switch.

I installed the RPD @ 2.2M which did not remedy the issue.

This happens both in and out of the box... no part subs.

any clue what could be causing this?

I was coming here to create a thread on my FatPants issue, Saw Mike B's post.. started to list my issue in his thread because I have the same but moved it out here to a new one so to not hijack his thread.

i just finished my FatPants build and it seems that I dont even start to get a boost until both knobs are turned up quite a bit on the body setting and even more without the body switch...

here is what Im getting...

Q2 @ 8.9V - Q1 @ 17.8V

Body switch OFF - Unity is with Volume at max and Fat knob at 12 oclock.
Body switch ON -  Unity = Volume @ Noon and Fat @ 0, or Both knobs at 11 oclock

If I ignore voltage and dial in the trimpot pedal for max boost Q2 is at 3.8V with Fat knob at max and body switch off...  it goes to 16v when I turn the Fat knob all the way down.

Hey all,

Building a FatPants and seeing some things for the first time and want to make sure I understand.

I see a +9v hookup, and also see the 18v markings... the pedal is powered by 9v correct? and the 18v comes from the 1044?

and therefore i need to make sure that all my caps are 25v or higher capacity correct?

any help is appreciated..

Hey Guys,

Breadboarded a sabretooth for a bass player friend of mine and had him try it out last night... I noticed that with the Fuzz knob turned all the way down the pedal was producing quite a bit of fuzz based on the fact that he had the volume knob on his guitar turned all the way up.

This makes the pedal very extreme and im afraid that he either would rarely use it, or if he did would never be able to bring if off very low settings.

Instead of forcing him to keep his volume knob backed way down on his guitar, is there something I can change on the circuit to get more usable controls?

We really like the sound of the subtle fuzz that was produced when he kept his guitar volume rolled back... I would prefer that this is what the pedal would sound like on low fuzz and then be able to bring it up from there...

I noticed that the Fuzz pot is a 2k pot.. would increasing this be a place to start?

It just seems like the circuit gets flooded too easily by the guitar volume knob.

any help is appreciated.

he was playing with a passive bass.

Or is there another bass fuzz circuit that I should take a look at?

thanks

Rob

Love this pedal... made 1 change to C12 to bring up the low end and rolloff some from the treble knob. Sounds great!

Hey guys,

Wondering if someone can spot where Ive gone wrong... I'm stumped.

I just finished my test rig and can't figure out why this is happening... I feel like its a stupid simple issue that I'm looking right past..



OK... So I have a GREEN wire going from the ground of the DC jack to the sleeve of the jack to its right (output) and a RED wire on the outer lug of the DC jack that goes to my RED alligator clip. I have a BLACK wire along with my audio probe on the TIP of the jack to the right (output). I have my WHITE Alligator clip on the sleeve of the input jack and my YELLOW alligator clip on the tip of the input jack.






I rigged a 9v battery clip to a DC plug which seems to test out correctly.






However, when I plug in the battery, clip the red wire to my red multimeter probe and touch the black MM probe to the sleeve of the jack to the right I get negative voltage.



Yet, when I hookup my test rig backwards to my MM, I get positive voltage..



Please tell me I'm not as stupid as I feel right now...

thanks

Rob
