would C1K still be the right pot if i go with the 100uF cap? i'd like to be able to dial in green russian big muff levels of low end at the extremes

hi @Chuck D. Bones, old thread i know but i had a quick question about this mod -- i get the basic idea of how it works, but i'm not clear on one thing -- does turning the C5K pot work by changing the series resistance to ground, which in conjunction with the 47uF cap changes the corner...

right, so i could increase the resistance to the LED portion of the optocoupler, thus decreasing the brightness of the LED, and increasing the resistance of the LDR. seems like a difficult way to try to increase the range though. i'd still like it to be as clean at the low end of the range as it...

what happens now when you turn the DRV knob all the way down, and what would you rather have happen?

hi all, i'm just about finished building my pandora's box with a couple of mods -- i added the CB bass mod, and borrowed the "drive knob" mod from the aion dynamo, which replaces the two switches with a B1K pot and 240R fixed resistor, for a variable resistance of 240R to 1.24K, a greater range...

can you explain a little more? if i had a switchable 2/4/6 stage phaser with a feedback control, would the feedback cause problems when switching it to 2 stages?

probably your best bet is to put these things on eBay and then use the money to buy the parts you need. fiat currency exists for a reason!

I believe centre-negative became the standard for guitar pedals because it made it easier to automatically switch the battery off when the DC jack was plugged in. now that batteries are practically obsolete in guitar pedals it doesn't make a lot of sense anymore, but it's the standard now and we...

i thought about it just a little harder and now i get why all of these have plastic exteriors. i thought the metal ones looked so great next to the input and output jacks, but... yeah, positive sleeve. makes sense.

hi all, i'm in the process of designing a phaser with switchable stages and from most of the circuit designs i've seen it seems like people generally try to avoid feedback for 2-stage phasers -- the MXR phase 95 and pedalPCB XC phase just put the feedback control after the 2/4 stage switch so...

okay i take it back, didn't see that. good thing you mentioned it before i hit checkout on my tayda order. anybody got a lead on some different externally-threaded DC jacks for a good price?

i recently made the decision to switch to these DC jacks since as far as i can tell they are the only affordable ones on tayda that are externally threaded. this allows me to mount and remove the whole circuit from the enclosure without having solder/desolder anything

what were your mods? or was that posted somewhere else?

So the version of the Expandora that I want to build is essentially the same as the Aion Effects Dynamo, with the two switches replaced by a "Drive" knob instead. And I think I want to add the Bass Pot described in this thread as well (instead of the bass switch on the Dynamo). Since I was...
