Which mods to the Complex overdrive did you end up with @Chuck D. Bones ?

Curious about differences and response of the Draco vs Boogie Monster. Read on the forum that it’s too mid scooped? Anyone try modding the mids behavior? And how do these compare to the Abasi Pathos and Wrectifier? Fet based vs opamp based. Also interested if someone build the around 20 years...

Indeed, but that was the printed value on the pcb already. ;)

R10 is 4k7 now so I will try a 3k3 as well. I don’t mind a little less bass boosting as there’s plenty of that already. EDIT: just replaced the R10 4k7 with a 3k3 resistor and it improved the treble a bit and also the response of the bass. Thanks @paulc!

R10 is a 4k7 now so I will lower that to 3k3 and give that a go! EDIT: for forum members that are going to build this I would advice them to use 3k3 instead of 4k7 for R10. ;)

I set the treble to full as well. I mentioned in my build report that it’s on the dark side otherwise. It’s mentioned as a passive treble at the end so I think it only cutting treble? For me the tone control switch also doesn’t work to my liking, would prefer a treble increase instead of a...

It helps if you can define what sounds weird?

I just posted a build report and quoted you in it. Did you build the PCB? I thought that it sounded quite cool. As a starting point set mids to off, bass to noon and treble to max. Volume to 2oc and gain to off for boost and higher for drive. Both switches in the middle position.

Cool build and great, amp like sounding pedal. Timmy on steroids. Boosts well with the gain to minimum and gradually adds overdrive up to quite some distortion when increasing the gain. The mids pot is where the zorks are. ;) With mids to minimum it’s flat but increasing it adds a very pleasant...

What influences the output of the pedal? More specially does Q4 influence the output? Unity now is around 12 oc or a little above.

I’ve used BF245A for now with an Idss around 5mA and VP around -1,9v. I used a 5k trimpot for R4 and had to increase 1,8k value to get the Q1 drain to 5v. Q2 drain was just above 5v with the 560r and Q3 above 8v. Used a 2n5088 for Q4 with HFE just below 500. It‘s already sounding pretty great...

@Chuck D. Bones lists 5x PF5102 in this post: https://forum.pedalpcb.com/threads/jfet-shootout.13363/post-149619 I will see which ones I have within that range and try how these work out after I finish the build, will also check the PF5102 when they arrive. EDIT: checked my JFET document and I...

It’s better to post my question about the transistors here: Does the Idss of the JFETs matter in this circuit? I have ones in stock like BF244a, BF245a, J113 which all have VP below 2v but Idss from 4mA to > 20mA. And the HFE for the 2n5089? I have 2n5088 here that have more gain then the...

I’ve build it and I think that it’s quite a cool alternative with a little more gain. Tone works a little better on this one. I would be curious about the Vemuram Butter Machine and TWA SH9 differences to the SD-9 @Robert ;)

Can you share a BOM for the Zorkmid @Robert?

I tried a Kliche buffer in front of the ElectroVibe (like the MBP Harbinger) and it improved the situation a little bit. Placement of the vibe is crucial and it’s best to experiment until you find what works best for you. Are you satisfied with the gain and bias settings?

This can help a bit: https://forum.pedalpcb.com/threads/this-univibe-schematic-what-part-would-you-change-to-brighten-up-the-tone.13496/

I remember reading that the brightness of the ElectroVibe can be influenced but I don't remember what you need to change then, I think others can chime in to give you some leads so you can experiment with some changes?

I just experimented a bit with a UAFX Lion 68 with the ElectroVibe Mini up front. I have different guitars with a treble bleed (HB, P90, single coils, HSS etc.) and on some I can switch the treble bleed in/out. There is a difference with the treble bleed active where it exaggerates the highs...
