I guess there's my confusion. I thought biasing was setting the voltage to 4.5 (VREF) in the power section. Why does it need the additional biasing resistor (beyond setting impedance)? I also just realized that is a different op-amp in the photo i linked. Since it's using the same pins and the...

Ok i'll try lowering the 1M, that's just how the stock Expandora is. For my own understanding, what is the resistor to VREF doing? I know it's common to have to set up 4.5v for op-amps to work, but what is the extra resistor doing in this case? Along the same line, why are the bias resistors...

I tried putting a 100nf cap in between the filter, before the 22k resistor and i fixed the dying sound. BUT it screwed with the overall tone quite a bit. It also introduced a weird fizz that pulses in an out.

I'm trying to add an active treble control to an Expandora but when I do and turn the tone knob fully CCW it kills the sound and gets almost gated. There's no other modifications made to the pedal at this time. Position of the treble knob doesn't seem to change anything. I'm using the same...

Bump for wondering if this exists

I'm curious what is the benefit of using the newly added rotary order switch vs the old 3pdt one? Thanks!

And you don't even need a 3PDT right? A DPDT has enough lugs

What is the benefit/reason to use 18v over 9v?

Hey ya'll i have a quick question about gain wiring and adjusting the minimum gain. I'm loving the expandora, but i don't like how when the gain is at 0 the effect volume goes to 0. So instead i want to essentially limit the gain knob so that fully CCW is equivalent to like 5% rotation of the...

People smarter than me. If this is the case, is there anything design-wise in a pedal we can do to avoid it? Like are certain designs more or less likely to be affected by this? Or is it 100% the amps fault?

I'm wanting to have a tremolo pedal where the rate can either be controlled by a preset knob or an expression pedal. Switchable by a footswitch. Does this wiring look correct to you? Thanks!

I build a warden for a friend and he's having some weird issues. It seems to work fine if he's playing regularly, but times where there's a lot of space in between notes or after taking a break he gets this issue: "If I stop playing for a bit while the pedal is on, the initial attack of the...

Maybe sort of how the Boss OC-3 can only effect lower strings if you want. Can you do something similar with gain? So maybe i want my higher or lower notes to clip and distort a bit, but not the others? Just spitballing here. I've haven't built the pedal yet, but is the Dunwich - Volt Thrower...

Missed out on the first run of them! Also is there any news on the 'Aqueduct' board. Would love that 8-in-1 vibrato and have been dying for it ever since it was announced

Is the full size Equinox drill template available anywhere? I've searched the threads and can't find it. Thanks!

Thanks for all the help, here's the final final one

Thanks again! For anyone else that pops in here and prefers visual aides here's the corrected wiring Still incorrect, see next post!

Although these days whenever I look up a guitarist's tone I really like they're using the SD-1.....

Oh I love the OD-3 way more! Never could gel with BD-2. It may be one of my fav bass drives though (Less I Know the Better anyone?) This is a commission for a friend, but he wanted some extra options outside of stock.
