I found out about a nifty piece of software from an old forum post. It tells you how the bass, mid, & treble controls on a variety of amps affects the frequency response (http://www.duncanamps.com/tsc/ (http://www.duncanamps.com/tsc/)). Among the amps represented is the Fender which is essentially the Alembic F1X circuitry if the values of capacitors #2 and #3 are changed to the Alembic's values.
So, my question: What are the values for C2 and C3 for the F1X? I looked up the values on the info sheet for the F2B, but the value for C2 is hard to interpret. There isn't a comparable sheet for the F1X that I know of.
Even if you use the default values for the Fender amp, it does behave as you'd expect given the various posts on our forum: 2/10/2 (b/m/t) gives you a fairly flat response; 5/5/5 gives you a mid-scooped response.
From a previous post (http://club.alembicguitars.net/index.php?topic=15059):
Zsrc = 38k
R1 = 100k
C1 = 250p
C2 = 47n
C3 = 100n
R2 = 250k
R3 = 250k
R4 = 10k
R5 = 1M
From another previous post (http://club.alembicguitars.net/index.php?topic=3427):
When you first run the TSC, click on the Fender tab. Next you need to make two changes:
Double click on C2 and change its value from 100 to 47.
Double click on C3 and change its value from 47 to 100.
Hi Dave, and thank you. This was what I first thought, but when I looked at the values for the F2B, which I thought was a two-ch version of the F1X, I saw some different values. Anyway, your answer clarifies everything thanks!
