That oscilloscope clip *finally* explained the chorus effect for me. Written descriptions always failed miserably. Thank you! Now I really want to see a phaser on the scope. People write about the “barber pole” effect, but I just don’t understand 😢

I used to work as a salesman in my local music store back some 8-9 years ago, & the description i've always given people who were dwelling in modulation for the first time was as follows: - Chorus sounds like water, gentle waves crashing softly. - Flanger takes the water & shifts into a storm/cyclone, where a plane is stuck in the eye of it trying to escape, but always falling & pulling up. - Phaser, depending on how many phases it has (2, 4, 6, 10), can either sound very subtle & warbly, to spaced out as if on some psychedelic trip. A vacuum sucking the air around, only to have it come back around for a duration of time (fast of slow).

Always good to see a non tube amp in the works. Especially grateful for demystifying the fabled chorus. 🤘

Replacing the op-amps had a huge improvement on the noise and bandwidth of the amp when I did it on mine. I used LM358s. Started off with NE5532s socketed but it caused a buzzing sound for about 5 seconds after start up. Not sure why. Love those little adapter boards

My repair shops have a decal with their contact information that they stick on the back panel. Some use paint markers and write on the tubes, I’m happy either way.

Roland Boss just loved using those SIP op amps. Those were a great, "howdy, fuck you tech", when you pulled the cover off and realized, "I don't have these in stock and I am not even sure where to find them". We had computer bulletin boards back in the 1980s but nothing remotely resembling the modern internet. I do have SIP 4558s & other op amps in stock, now. A typical non-modulated chorus effect is generally a delay of between about 45 milliseconds and maybe 75-90 milliseconds. If you have a digital display, digital delay, stay away from 60 MS. That delay will eat up most A notes' sustain with standing waves. Mathematically it makes no sense, but it still does it. Other chorus delay rates will kill other notes. Flanging is generally single digit up to 20 or 30 millisecond delay. Jimi Hendrix & Eddie Kramer used hand flanging which is where the term flanging comes from. Run your track on two synchronized RtR tape playback decks and drag your fingers on the pay out spool's flange of one of them. The flanging rate varies and it's a unique sound. Albums like Crash Landing & Cry of Love have more of the hand flanging. They also used a slinky in place of a spring reverb on one or two tracks. There is even a credit from whomever was shaking the slinky around.
