Hi, I built this monter recently. Noticed that on the schematic the capacitor below Q1 is 220nF instead of 100nF, I used the 100nF though.
ReplyDeleteMy build, worked partially. So the treble knob did work, the volume knob only the first 2/10 (I have to admit I used a 100kB, instead of 100kA; guess the logarithmic works better). This effect has a lot of sustain.
Unfortunately when I tried to check on my mistakes or shorts (the switch wiring is kind of a nightmare) I made it worse! Less is working. Need ta break on this one. Also in the schematic at the input the 1uF and 1k are in opposite sequence, I kept it the same way since it's easier to insert the parts, don't know if this influence the sound a lot.
Then I also omitted the mods, pF capacitor and trim pot.
Oh I I didn't had a 680k, used a 560k. I might add a 100k.
ReplyDeleteHey you can tag this one. I subbed all of the transistors to a bc183, some bc550b’s, and a bc184lc. I forgot to match the pair but the octave is not lacking. The volume could be a linear taper for a better spread and I suppose the gain could be too. Treble is pretty subtle but it does more with certain settings over others.
ReplyDeleteVery glad to find this layout, as Dead End FX is on pause due to a postal strike! I was about to snag his Zuperbee... :( I'd love to incorporate his mods into your layout - especially a switch to include the 6th transistor in the Starve function. Possibly the other additions too... I'd be incredibly grateful if you could give me some guidance on that - thanks SO much! Excellent, excellent blog.
