    Can I safely use 12V power supply with Phase II ?

    Hello, I am considering taking the Phase II circuit out of the enclosure, to put it somewhere inside a digital piano Korg SP170S running on 12V. Schems : https://www.manualslib.com/manual/1313552/Korg-Sp-170s.html https://www.pedalpcb.com/docs/PhaseII.pdf Do you think the phaser can take...

    What was your first PedalPCB build?

    Arkaim Fuzz. At first, the description on musikding got my attention ("wall of fuzz for bass and guitar"). The original circuit and its reviews convinced me to build it. It was in january 2020, and then, I only knew the Zvex Fuzz Factory, which is very special and raised my interest in fuzz...

    Flanger To DIY or not to DIY?

    I built the Flintlock, and the Flangelicious. I like them more than the BF-3 I bought. Both have some background noises at specific settings. Flangelicious has a "faucet/ water noise with Manual past 12'. You can get a perfectly clean modulation by changing the noise/signal ratio (increase...

    Mxr sub machine

    This effect is obviously really good, as usual with mxr. It is very different from the blue box (which is more synthy and glitchy), and I don't think there is a DIY clone available anywhere yet. Bassists and guitarists would be very excited ! I agree with this suggestion. I read it's based on...

    SOLVED Pacifier transistor voltage question

    This Pacifier sounds much better now. I'm going to spend some time playing with it. Thank you very much for your help !

    SOLVED Pacifier transistor voltage question

    Hello, I received both transistors today. here are my readings on Q2 : 2n2369a E = 0 B = 0.623 V C = 2.795 V 2n4401 (180 hFe) E = 0 B = 0.561 V C = 0.444 V I guess I should use 2n2369a for Q2 ?

    I placed an order for 2n4401 and 2n2369A at my local store. I should be able to give you my results by the end of next week. Thank you for your help !

    SOLVED Pacifier transistor voltage question

    Ok here it is (multimeter set on DC voltage) : E = 0V B= 0.575V C = 350 mV

    SOLVED Pacifier transistor voltage question

    I forgot to say that the first readings I posted were taken with the circuit powered and switched off. Here are my readings at Q2 when it is switched on, and all pots set on the middle of rotation : E = 0V B = 260 mV (0.5V with all pots fully CW except Tone) C =2.2 V

    SOLVED Pacifier transistor voltage question

    Yes I do, there is a plugging location on my DMM : I read Q1 = 0309 hfe Q2 = 0313 hfe Q3's leg are a bit too short to fit in the DMM, but it was OK if I read you correctly. I removed all transistors...

    Bypassing fuzz part in corduroy fuzz

    Did you try with some other effect (an other drive for exemple) placed before the Corduroy and powered on ? I have a noise that kills all the guitar signal. It disappears if the voicing switch is set down, or if I turn off the other effect, or if I switch on the regular fuzz mod.

    Bypassing fuzz part in corduroy fuzz

    Everything works fine, but when the pedal is on "Plexi mod", if there is an other effect engaged before the Corduroy, there is a big weird noise that appears when the tight/fat switch is set upward. Maybe an impedence issue? Does anybody else have this trouble ?

    SOLVED Pacifier transistor voltage question

    Hello, I've built a pacifier and I am wondering if my voltages are ok on the three transistors. https://www.pedalpcb.com/docs/Pacifier.pdf On my build I read Q1 C = 2.6V B = 0.647V E = 0 Q2 C= 360mV B= 0.5V E= 0 Q3 C = 9.19V B = 4.19V E = 3.6V Q1 & Q2 values seem strange, so I removed...
