Hey everyone
I've attempted to build this janglebox:
http://tagboardeffects.blogspot.com/2014/06/janglebox.html twice and have had the same issue both times. Instead of getting the desired compressor effect, I am getting an overdrive/distortion sound. Instead of using a trimmer, I used two 470R resistors which I thought would be similar to a 1k trimmer set at the center. I used a CA3080 for the IC (two separate ones for each build which were substituted for each other)
If anyone knows where to find the schematic for this layout, I think that would help me out a lot.
Here are the voltages I am getting
IC:
P1 0.06
P2 3.06
P3 3.08
P4 0
P5 0.08
P6 7.56
P7 9.67
P8 8.94
Q1 E 2.46
B 2.82
C 9.67
Q2 E 6.85
B 7.56
C 6.85
Q3 E 0
B 0
C 8.65
Q4 E 0
B 0
C 8.64
Q5 E 8.89
B 8.61
C 9.67
Here are some pictures:
I followed this thread
http://tagboardeffects.blogspot.com/p/forum.html and the issue was with the CA3080. Does anyone think that the chips would be causing my issues? Or would my transistors be causing the distortion?
Any help is greatly appreciated!
