Current Lover trim pots

[hagcel]

I finished off a current lover tonight.

It has a really great sound but more subtle than I would like and more subtle than my electric mistress. Almost sounds more like my deluxe electric mistress.

To get a great / more extreme  flange tone I end up with noise at the bottom on the flange sweep.

Both trim and bias have a very small usable range. Only around extreame clockwise (1). Trim has a great sound in the middle of the trim pot but I can't bias out the sweep noise.

Does this all sound correct?

This is a 3007 version.

One other thing. I added D4, D5 and C5. I realized I shouldn't have and I just clipped them out of the board. I did jump C5 and I did jump IC2. Do I need to suck the solder out of D4 and D5 or is it fine as is?

I can change out the 4558 for a TL072 without issue? I had done that in my DMM and DEM with nice results but from some reading I had done that might have only been a good change because of the low input impedence, maybe it won't benifit this circuit?

Thanks!

try 12v adapter. You'll have to rebias but you'll get much more usable range.
