I remember reading something about an effect that would play the guitar part, but would also play the bass. What is this effect called? Is there a schem?
I don't know what you call it. I suppose it would be under the category of "automatic harmonizer".
I can't imagine anyone doing this with an analog circuit, so a schematic wouldn't do much good. This is most often accomplished as a digital signal processing trick. The closest you can get to this with a reasonable analog circuit is a pitch shifter, which is not as interesting as it simply plays exactly what you're playing, just one or two octaves down.
yeah, its called the boss oc2/oc3. It's got the regular volume, the volume of 1 octave lower, and the volume of 2 octaves lower (bass guitar)
just check out the 4013 flip flop in the blue bix scheme....and add it to any thing you want pretty much...

if you add a little drive before the boss pedal and some low pass filtering. like two notches it greatly hleps this unit out in tracking..
Also the Rocktave. Supposedly the best tracking of them all (and it is good, although still with quirks). The Bluebox is great fun, but mainly for it's mistakes: it gets this really wild thing going when you whack a low E and the pedal gets confused - skipping between octaves, other notes at times. It's cool, but not a clean octave. A microsynth also has octave down.
I'd go with the rocktave, or buy an OC2.
hih
the maestro octave box. it had a rudimentary non-adjustable attack/release vca controlling a deep bass thump, which was only applied to the beginning of any note or chord you played.
I have an OC-2 and it's amazing. Actually, a bass is only 1 octave lower than a guitar. Try playing an E on a bass's D string and play the low E on your guitar. It'll be the same ;) I find the 2nd octave on the OC-2 only usefull above about A, and usually it sounds best above B or C.
But I like the pedal, its tracking is amazing and keeps up, even with fast bits :)
I think what Matt is after is something like what Roland has. With a special pickup you can separate the lower strings (1,2 or 3) and apply an octave down only on them. The only way (I think) without a split pickup is RADICAL low-pass filtering, to cut off the higher notes. Maybe the first octave off a guitar would be good. Don't know if that would work in practise though...
Saber--OT, but I like your signature.
I'm one of the 10 people that understands binary...too bad for the other guy.
Thanks guys and I also like the binary sig. That's hilarious (well at least to geeks like us)
I'm sure I remember the guitarist from the Dirty 3 (they have no bass player) using a bass notes player kind of device in the early to mid 90s. I Don't think it was just and octave pedal and just used a regular pickup
